Industrial convergence refers to the dynamic process in which different industries gradually form new industries through mutual penetration and cross. As an advanced form of industrial synergy, industrial convergence is crucial in building a modern economic system. Using a panel data set covering China's 30 provinces during 2006–2018, this study explores the impact of industrial convergence on regional high-quality development. The findings suggest that: (1) Industrial convergence is conducive to high-quality development, and this conclusion remains robust after a series of tests. (2) For heterogeneity, the positive impact of industrial convergence on high-quality development is greater in regions with optimized energy structure and high investment outward, as does the regions with reasonable financial structure and moderate economic agglomeration. (3) Productivity improvement and industrial upgrading are the mediating paths by which industrial convergence promotes high-quality development, and the former plays a greater role.

In today's fast-paced and dynamic work environment, stress management is key to creating a harmonious and productive workplace. Workplace stress is not only a challenge but also an opportunity to improve personal well-being and professionalism. This research aims to explore practical and proven stress management strategies that can improve the quality of the workday and work outcomes. Based on the Systematic Literature Review (SLR), practices such as mindfulness and programs such as Mindfulness-Based Stress Reduction (MBSR) are proven to reduce emotional exhaustion and improve employees' psychological wellbeing. In addition to individual stress management, these strategies also positively impact team dynamics by reducing interpersonal conflict and encouraging collaboration. However, implementation of stress management practices in the workplace often faces barriers such as resistance to cultural change and insufficient support from management. Overcoming these barriers requires a comprehensive approach that involves education, training, and the development of supportive policies. An organizational culture that prioritizes mental health and leadership that emphasizes employee well-being is critical to the long-term success of workplace stress management techniques. By integrating these strategies, this research aims to empower individuals and organizations to control stress, increase job satisfaction, and achieve professional goals more effectively.

Access to safe drinking water remains a global challenge, primarily due to the prevalence of water contamination in various regions. Numerous methods have been explored to address this issue and convert polluted water into potable sources. However, the cost associated with these methods often hinders their widespread adoption. Solar distillation, harnessed by abundant solar energy, emerges as a promising and sustainable solution. Although solar distillation technology has made significant advancements in recent years, the endeavor to boost its efficiency remains a substantial challenge. Typically, solar stills yield between 4 and 6 liters of fresh water per square meter of solar still per day under ideal circumstances. Notably, both single‐basin and double‐basin solar stills have been extensively researched to discover methods for enhancing their productivity. A notable innovation in this field, the tubular solar still (TSS), has gained recognition for its capacity to improve productivity. The present review article systematically examines the development of efficient and cost‐effective solar distillation systems on a global scale. It provides a comprehensive analysis of the literature pertaining to techniques employed to enhance TSS performance. The study categorizes these techniques, conducts in‐depth evaluations of both experimental and simulation studies, and offers a meticulous comparison of various strategies to optimize TSS functionality. Furthermore, the article identifies existing research gaps and puts forth prospective directions for advancing TSS efficiency. [ABSTRACT FROM AUTHOR]

The global steel industry is rapidly transitioning towards energy decarbonization to address the climate crisis. Sintering is one of the main sources of greenhouse gas emissions from steel mills. Traditional sintering processes use straight inclined chutes to feed raw materials into the sinter machine. However, this design suffers from insufficient horizontal momentum, resulting in poor segregation of the layered materials. This study proposes an improved charging chute design profile that uses a cycloid curve and rolls to enhance segregation, thus reducing coal consumption and increasing productivity. To achieve this, we first modeled a charging chute using the cycloid curve. Secondly, building upon the cycloid concept, we created a roll-type chute by strategically placing rollers along the cycloid trajectory. Finally, the cycloid roll-type charging chute, integrating the cycloid trajectory with the roll-shaped charging chute, was simulated. Pilot tests comparing the cycloid roll-type and straight chute models demonstrated a significant increase in dispersion for the cycloid roll-type design, with a 65% improvement in the Strand-ward segregation (Sw) index compared to the straight chute. Furthermore, actual filed implementation in a sintering process achieved a 2.9% increase in operational productivity and a 6% reduction in fuel consumption. This study is significant not only for proposing an optimal chute design, but also for successfully implementing it in a full-scale steel mill, contributing to a reduction in fuel consumption and carbon reduction in steel mills.

This paper proposes a data-driven procedure to improve productivity in make-to-stock manufacturing. By leveraging recent developments in information systems research, the paper addresses manufacturing systems with high process complexity and variety. Specifically, the proposed procedure draws upon process mining to dynamically map and analyse manufacturing processes in an automated manner. This way, manufacturers can leverage data to overcome the limitations of existing process mapping methods, which only provide static snapshots of process flows. By bridging data and process science, process mining can exploit hitherto untapped potential for productivity improvement. The proposed procedure is empirically validated at a leading manufacturer of sanitary products. The field test leads to three concrete improvement suggestions for the company. This research contributes to the literature on production research by demonstrating a novel use of process mining in manufacturing and by guiding practitioners in its implementation.

This research paper aims to use lean six sigma tools to handle milk in small Brazilian dairy estates. The search for efficiency in this process preponderates in all productive sectors. However, it is still not exploited in the dairy chain, specifically by small-scale producers, although milking is the main income for many of them. In Brazil, small producers are the main suppliers of the chain, and maintaining their competitiveness requires specific actions. Therefore, through the action-research method, four small producers in the center-west of the state of São Paulo, Brazil, were involved in identifying problems in their milking management process, investigating and implementing practical solutions. To this effect, lean tools such as flowcharts, Ishikawa diagrams, value stream mapping, and PDCA cycles were employed, and six feasible improvements were defined. The successful implementation of said improvements led to the acquisition of knowledge by small producers, who received financial returns, i.e., an increase in the amount paid per liter of milk. This research shows that, through interdisciplinarity, positive solutions to problems of different and complex natures, such as those in the dairy chain, can be obtained.

In today's era of digitalization and competitive market environment, organizations are more focused on manufacturing quality products at optimum cost to capture maximum business as a variety of options are available to customers for purchasing goods and services. In this scenario, the latest technologies-based productivity improvement can help organizations to achieve set targets of production and ensure the quality of products. In this study, the contactor manufacturing industry has been considered to demonstrate integrated Lean Six Sigma with the Internet of Things (IoT) approach for productivity improvement. A systematic literature survey was performed to understand the concept of Lean Six Sigma (LSS), Define Measure Analysis Improve Control approach and IoT technology. The implementation of the LSS approach reduced the rejection rate of contactors and saved the total production cost (Rs. 51,88,260/-) annually. The annual consumption of grinding wheels has been reduced by 8 quantities to produce the same quantity of contactors. The surface quality of magnets has been identified as a root cause for contactor rejections as it contributes 53.4% of total rejections. The improvement measures are recommended based on the expert's suggestions as grinding wheel dressing must be performed after the completion of a batch of 20,000 parts. The condition monitoring and IoT approach implementation are done by monitoring grinding speed (650–950 RPM), grinding wheel thickness reduction by 0.4–0.6 mm after dressing and dressing of grinding wheel after completion of 20,000 for reducing rejections. This study concluded that industries should implement the Lean Six Sigma approach with the latest technologies and appropriate tools at each stage to set processes to world-class standards and industries should identify opportunities for process and product improvement.

Introduction: Productivity is an important topic in knowledge management that plays an effective role in improving the optimal use of resources, services and employees. With knowledge management, economic, technical and cultural attitudes towards production and organizations in a competitive world, they are intelligently trying to get the best results with the least cost and time from their activities. In the meantime, university libraries, as "knowledge portals" and organizations active in the public sector are bound to improve the efficiency of financial resources, maintain information resources and knowledge forces and improve the efficiency of knowledge management is considered a necessity for libraries to maintain efficiency. Therefore, the present study was conducted to provide a model for improving productivity in academic libraries as a roadmap for their future. Methodology: The current research is based on the fundamental goal and qualitative nature and is a part of exploratory research that was carried out with the "grounded theory" approach. The statistical population of the research includes 16 experts and faculty members of universities in the fields of management, knowledge and information science, and information technology. The interviewees were selected based on having sufficient history and experience and being interested in the research subject and they were selected according to their expertise and skills using; the purposeful sampling method. Research data was collected using a semi-structured interview method with a systematic approach and using open questions. After each interview, to increase accuracy, the interviews were reviewed so that if there was any ambiguity in the understanding of the stated content, it couldbe corrected with the opinion of the interviewee. After performing the initial steps of analysis, to ensure the correctness of the interpretation, the content and their interpretation were again presented to the participants so that the content can be edited by the interviewees if needed. In the end, the data validity and reliability method with four criteria of credibility, transferability, dependability and confirmability of Lincoln and Guba was used to measure the reliability of the results. To analyze the data, a three-stage design of open, central and selective coding was used. Findings: In examining the categories, during the coding process of 281 open codes from the data obtained from the research interviews, 71 subcategories were coded and extracted. Then, axial coding was done based on the paradigm model. At this stage, the codes that had similar concepts were gathered in the form of a family under one concept. Finally, by using the selective coding of the conceptual model in the form of a paradigmatic model of the categories were outlined as: a) causal conditions؛ communication channels, management factors, organizational factors, individual factors, technical factors, b) the main phenomenon; Improving the productivity of knowledge management, c) Intervening conditions; external factors and internal factors, d) background conditions; motivational factors and internal organizational factors, e) strategies; Designing a creative and efficient system, designing an information economy system, designing an integrated content management system and designing an efficient system for supporting academic staff, f) consequences; Rapid shring of knowledge, cost reduction, accessibility of resources, improvement of the work of knowledge workers and tangible income generation from knowledge Conclusion: The drawing model showed that the extracted pattern of the research can be used as a roadmap to achieve the goal of improving the efficiency of knowledge management in university libraries, especially in the economic recession when libraries are in the purgatory of services; on the one hand, libraries are obliged to distribute information fairly and on the other hand, the staggering costs and the lack of facilities have reduced the ability to provide appropriate services. Therefore, it seems that the creative economy strategy, which is based on art, culture and sciences can lead to the information economy. Libraries earn money through digital information and services, production, distribution, marketing, pricing, sales, storage, and processing; of information compensate for part of the costs. Of course, it should be noted that the creation of knowledge management infrastructure for the development of new technology equipment and digital communication requires cost and investment. As a result, it is expected that library services will be effective and efficient against the costs it creates. Therefore, it seems that paying attention to the creative system, information economy, integrated content management system and the use of creative forces can be effective in improving productivity. Of course, on the condition that the evaluation of the effective factors of productivity, the examination of strengths and weaknesses, the use of creative methods, and scientific thinking in removing obstacles to improving productivity should not be forgotten.

Construction supervision is a crucial element in organisational/managerial practices, which provide blood circulation to the project operations by directing labour. Accordingly, this study aims to quantify the impacts of crucial organisational/managerial elements on the efficiency of labour in building construction projects based on the viewpoint of construction supervisors. Findings – A total of 28 factors were determined as critical, where lack of labour motivation, poor labour training facilities, poor performance evaluation practices, no labour rewarding mechanism and poor communication/cooperation between parties were judged to be the top five key issues in the list. The validity and reliability of the study findings were ensured through statistical tests and the experts' discussion outcomes. In view of the evolving challenges facing the industry, the results indicate that the organisational policies of construction enterprises in place addressing financial procedures, communication strategies, resource management and performance management practices must be enhanced. Research limitations/implications – The study findings will make a substantial contribution to reducing the disparity between organisation/management policies and labour practices towards changing how the sector operates to increase labour efficiency in construction projects. Originality/value – This study contributes to addressing the knowledge gap in the industry associated with the organisational protocols, especially to understand/predict how such elements are significant, how much they influence the efficiency of construction practices and what steps can be made to limit their effects on labour efficiency in construction. These could be crucial in modernising organisational policies and procedures for construction management.

Thailand’s government allocates part of its budget to supporting and promoting the international competitivenessof SMEs since SMEs in Thailand account for 42.2% of the GDP. However, the competence in Industry 4.0 technology seems to show only minor improvement. This study aims to extract the problems reported when conducting a project to promote digital technology for transforming SMEs’ manufacturing processes. The data were collected from 187 SMEs of all sizes across all sectors in the central region of Thailand during 2018–2019. In summary, Thailand’s SMEs are mostly categorized at level 2.0 in industrial technological advancement. The most frequently reported problem was the lacking systematic planning and control of the production process, leading to low-performance efficiency and waste in the process. This problem also caused barriers to the lean automation transformation scheme. Despite the support from the government in technology and investment consultancy, smart technology and techniques forperformance improvement and process standardization should be provided to facilitate SMEs’ leap towards Industry 4.0 sustainably.

The operation of a high-voltage distribution system is risky to workers in many respects, as it involves long hours of work and the need for postures that affect employees’ health, causing performance degradation. The aim of this research is to improve these aspects by studying the tasks, time required, and postures. This is combined with an ergonomic risk assessment in which we use rapid entire body assessment (REBA) to analyze the risk arising from employees’ postures when working with high-voltage distribution lines with mobile elevating work platforms (MEWPs). We examine 10 processes with the aim of increasing productivity and reducing the ergonomic impact on employee health. The results indicate that problems are caused by the equipment used and the work methods, which cause delays. In addition, most of the postures also involved ergonomic risk at the high to medium level. We therefore introduced improvements by modifying and designing equipment to make it suitable for operation according to the ECRS principles, established postures that posed the least risk, and verified that this improvement did not cause further impact. Following this, the Digital Human Model (DHM) was used with the CATIA V5 program to improve the working methods. After the improvement, the overall working time was reduced by 16.00%, a maximum efficiency increase of 31.85% was found, and the ergonomic risk at the very high to high level was reduced by 87.24%.

Recently, the reverse osmosis (RO) process is widely used in the field of desalinating brackish water and seawater to produce freshwater, but the disadvantage of using this technology is the increase in the rates of electrical energy consumption necessary to manage these units. To reduce the rates of electrical energy consumption in RO desalination plants, geothermal energy and photovoltaic/thermal panels were used as preheating units to heat the feed water before entering RO desalination plants. The proposed system in this study consists of an RO desalination plant with an energy recovery device, photovoltaic/thermal panels, and a geothermal energy extraction unit. To evaluate the system performance, three incorporated models were studied and validated by previous experimental data. The results indicated that incorporating the geothermal energy and photovoltaic/thermal panels with the RO desalination plants has positive effects in terms of increasing productivity and reducing the rates of specific power consumption in RO desalination plants. The average saving in the specific power consumption for utilizing the thermal recovery system of PV panels and geothermal energy as preheating units reached 29.1% and 40.75% for the treatment of seawater and brackish water, respectively. Additionally, the economic feasibility showed the saving in the cost of freshwater produced from the RO desalination plants for incorporating both geothermal energy and photovoltaic panels with a thermal recovery system with reverse osmosis desalination plants of up to 39.6%.

The most interesting themes worldwide are those relating to sustainable water and energy supplies. They have a significant impact on any society's economic wellbeing. Desalination of brackish water has proven to be a good solution to the freshwater issue that many regions of the world face. Solar stills (SSs) are a simple distillation technique for freshwater purification. From the conventional SSs to the modified SSs, several studies have been carried out to improve the effectiveness of this technique. Pyramid solar stills are effective and efficient, according to researches that have been done to develop several types of solar stills for increased distillate production. In this review, we aim to provide an extensive review of recent advancements in pyramid solar distillation techniques, including new technologies, methods, and best practices. Consequently, this paper helps researchers choose the optimal technique to get the best-optimized productivity from a pyramid solar still. This review highlights the efforts of researchers to improve the efficiency of solar distillation systems by exploring recent techniques and innovations in pyramid solar distillers up to 2023. Various results have demonstrated the significance of modifications or improvements to pyramid SSs, such as utilizing storage materials, which can significantly increase productivity by approximately 35%. Additionally, a v-corrugated absorber with PCM can enhance the yield by about 87.4%. Furthermore, the use of wick materials can increase freshwater production by up to 122%, with jute wick outperforming cotton wick. Integrating evacuated tubes and carbon black nanofluid into a pyramid solar still can also improve freshwater production by approximately 57.1%. Combining nano and wick materials can further boost pyramid distiller productivity by up to 176% and increase thermal efficiency to 60.44%. Moreover, using pyramid distillers with revolving cylinders and electrical heaters can result in a daily output increase of 214%, producing up to 9100 ml/m2/day.

Manual handling of hot and heavy workpiece in forging press industry increases the process time and causes safety risks to workers. To increase the productivity and optimise the use of manpower, manipulators are needed to be designed for supporting the workers handling the workpiece. Designing robots for such applications is challenging since the robot suffers from a heavy payload at the arm tip, and it operates at a high speed in a large workspace. This research addresses the design and implementation of a novel robot for handling workpiece for a given forging press cell. A novel robotic mechanism is designed with two key features: (i) the addition of parallel links in between serial links and (ii) the use of hydraulic actuators for driving robot's joints. The addition of parallel links and the use of hydraulic cylinders are to increase the structural rigidity. It is also to reduce the number of joint variables and restrict the end-effector moving parallel to the ground surface so that the robot grips and releases the workpiece in a more efficient and simplified manner. The effectiveness of the designed robot mechanism is demonstrated through functional tests, and experimental results are carried out on the implemented robot. [ABSTRACT FROM AUTHOR]

This paper explores how different routing techniques for the battery management of automated guided vehicles (AGVs) can affect the performance of a system. Four heuristics available in the literature were the basis of this study. Simulation models were developed to investigate how the routing of an AGV towards a battery station can affect the productivity of a manufacturing facility. Results show that the best productivity can be achieved when a routing heuristic tries to jointly minimise the total travel distance and waiting time at a battery station. The gain in productivity, when compared with the highest possible gain theoretically achievable, is quite substantial. It was also found that higher frequency of decision-making (i.e. decisions with smaller time interval) about battery swapping helps to increase the productivity of a system. [ABSTRACT FROM AUTHOR]

This paper introduces a case study to improve productivity of a multi-product transmission case machining line at a motorcycle manufacturing plant. First, the manufacturing process is introduced to characterise the production flow. Through structural modelling, such a process is simplified through aggregations and transformed into a two-stage Bernoulli line model with split dedicated machines and finite buffers. Using Markov chain analysis, the system throughput can be estimated. The results are validated by plant data. To improve system productivity, through numerical experiments, we investigate the impacts of increasing machine efficiency, varying demands and implementing different loading policies. Such a study provides a quantitative tool for plant engineers and managers to improve production operations. [ABSTRACT FROM AUTHOR]

Thailand's government allocates part of its budget to supporting and promoting the international competitiveness of SMEs since SMEs in Thailand account for 42.2% of the GDP. However, the competence in Industry 4.0 technology seems to show only minor improvement. This study aims to extract the problems reported when conducting a project to promote digital technology for transforming SMEs' manufacturing processes. The data were collected from 187 SMEs of all sizes across all sectors in the central region of Thailand during 2018-2019. In summary, Thailand's SMEs are mostly categorized at level 2.0 in industrial technological advancement. The most frequently reported problem was the lacking systematic planning and control of the production process, leading to low-performance efficiency and waste in the process. This problem also caused barriers to the lean automation transformation scheme. Despite the support from the government in technology and investment consultancy, smart technology and techniques for performance improvement and process standardization should be provided to facilitate SMEs' leap towards Industry 4.0 sustainably.

Introduction and purpose: Job performance is the most critical organizational issue determining the survival or dissolution of an organization. Professional ethics are among the major factors promoting job performance. Since professional ethics and job performance contribute greatly to the enhancement of productivity, the present study aimed to assess the relationship between professional ethics and job performance of staff in selected hospitals of Shahid Sadoughi University of Medical Sciences in 2021. Methods: This applied research was conducted based on a descriptive cross-sectional design conducted on 180 employees of selected hospitals in 2022. The subjects were randomly selected and administered the Work Ethic Questionnaire of Gregory, C., Petty, and Job Performance Questionnaire by Patterson. Data were analyzed in SPSS software (version 16) using Kruskal-Wallis and Mann-Whitney tests. Results: The results pointed to a positive and significant relationship between professional ethics and job performance. The correlation coefficients of "interest in work', "perseverance", "healthy relationships", "collective spirit and participation in work" were reported as 0.355, 0.551, 0.483), and 0.386, respectively. Demographic variables (marriage, education, age, and professional experience) showed a significant relationship with professional ethics, and demographic variables (gender, marriage, age, and work experience) were correlated with job performance. Conclusion: As evidenced by the findings of this study, the promotion of ethics can increase employees' job performance. Since job performance directly improves organizational productivity, these two variables deserve assiduous attention.

This study aims to identify the factors affecting productivity management and rank its improvements within government service organizations. In terms of the type of data, this is a descriptive, applied, and inferential survey, and it is both qualitative and quantitative. This paper follows a three-step process. The theoretical sampling method was thus used to select a sample of 15 productivity experts from within the university and managers from government organizations in Tehran province for semi-structured interviews. It is a specialized sampling method. The interviews were analyzed using NVivo Plus software. Additionally, 102 items were derived from the interviews, based upon open coding, and classified into 21 sub-indexes and two main indices. As part of the second stage, the quantitative aspect of the research, Shannon Entropy, was used to determine the importance of various factors affecting productivity management. The third stage of ranking productivity improvement strategies in public service organizations utilized the MABAC method. The results showed that the indices of accountability, work experience, interdepartmental challenge, expertise and skill, flexibility, interdepartmental communication, training, workload, structure transparency, information and communication technology, organizational culture, safety and health, research and development, leadership style, innovation, and creativity, respectively, gained the highest degree of importance among the factors affecting the productivity management of government service organizations. Further, research findings indicate that improving service efficiency, improving service standards, improving service effectiveness, developing a program to improve service productivity, encouraging leadership involvement, and establishing periodic monitoring are the most effective strategies for improving productivity in government service organizations.

The aim of this study is to define a robust estimation model of the most dominant labour productivity measurement, Hours per Vehicle (HPV), in the auto industry. Data utilised in this study were from 10 different multinational North American carmakers from 1999 to 2007. Through a comprehensive literature review and practical consideration, 13 important variables that affect HPV were defined and developed. Several robust and advanced statistical methods were utilised to determine the best possible HPV regression equations. The MM estimator, multiple M-estimator, was defined as the best method to perform the data analysis and to derive the robust regression model to estimate HPV. Depending on the car class, the vehicle variety, model types, annual working days, car assembly utilisation and launching a new model penalise HPV; however, annual production volume, flexible manufacturing and year of production improve HPV. Moreover, Japanese plants are the benchmark regarding HPV followed by joint ventures, and American plants. [ABSTRACT FROM AUTHOR]

The operation of a high-voltage distribution system is risky to workers in many respects, as it involves long hours of work and the need for postures that affect employees health, causing performance degradation. The aim of this research is to improve these aspects by studying the tasks, time required, and postures. This is combined with an ergonomic risk assessment in which we use rapid entire body assessment (REBA) to analyze the risk arising from employees postures when working with high-voltage distribution lines with mobile elevating work platforms (MEWPs). We examine 10 processes with the aim of increasing productivity and reducing the ergonomic impact on employee health. The results indicate that problems are caused by the equipment used and the work methods, which cause delays. In addition, most of the postures also involved ergonomic risk at the high to medium level. We therefore introduced improvements by modifying and designing equipment to make it suitable for operation according to the ECRS principles, established postures that posed the least risk, and verified that this improvement did not cause further impact. Following this, the Digital Human Model (DHM) was used with the CATIA V5 program to improve the working methods. After the improvement, the overall working time was reduced by 16.00%, a maximum efficiency increase of 31.85% was found, and the ergonomic risk at the very high to high level was reduced by 87.24%.

The accumulation of process waste in the production line causes fluctuations, bottlenecks, and increased inventory in workstations disrupting process flow. In this paper, the optimal process flow that will improve productivity using simulated value stream mapping (SVSM) for decision-making to provide consistency, minimise errors and non-value adding times in the implementation phase of VSM in the truck manufacturing industry. The proposed methodology applied a discrete event simulation for production process operations improvement to eliminate non-value adding times and provide good quality products at the lowest cost and highest efficiency. The results are the analysis of the current state of the production system in a South African truck manufacturing industry as a potential solution for the production system's future state. The identified non-value adding times in the six most critical workstations were eliminated by SVSM resulting in a productivity improvement of 4%, most importantly bringing the productivity to 95% and total cycle time improvement to 451 for small units and 466 for large units. The results proposed combined VSM and simulation techniques based on empirical data from the observation during time measurement. The Yamazumi confirms the issues observed and the NVA recorded by showing how close the process cycle times are to the TAKT time, which enhance the LEAN application by DES to increase productivity and performance improvement to remain competitive in the global economy.

Japan is undergoing a social transition with a decreasing workforce in the construction industry; therefore, improving productivity is an urgent issue for sustaining social infrastructure. This paper presents a quality control system for road pavement construction, relying on non-destructive and automatic measurement for compaction quality control. The system’s applicability and measurement accuracy were verified in 2020 and 2021 for national highway pavement construction, commissioned by the Ministry of Land, Infrastructure, Transport and Tourism. The system is labor-saving and has equivalent accuracy to the currently used transmission RI for compaction quality control. This paper reports on an overview of the verification.

Large-scale public construction projects often become expensive white elephants requiring considerable postconstruction maintenance. Thus there is a pressing need to integrate construction and postconstruction stages into productivity measurement and analysis. However, previous studies of productivity measurement focused on the efficiency of the project delivery phase, but overlooked the utilization of the constructed facility. This paper developed a two-stage construction project productivity (CPP) measurement model by integrating site efficiency (SE) and utilization effectiveness to investigate strategies for improving the overall CPP. An as-usual setting, which delineates the measurement of CPP, was developed as the benchmark model. Given the relative nature of the productivity concept, two scenarios were considered for CPP improvement. The enhancement scenario was introduced by adding a requirement that CPP is enhanced compared with that in the benchmark model. Then a transcendence scenario was developed to ensure that CPP is better than SE. Strategies for CPP improvement were formulated and were analyzed using the analytical models developed. This study for the first time distinguished the substitutionarity and complementarity between facility occupation and facility management in the postconstruction stage, and claims that the opposite natures offer opposite strategies for CPP improvement. The empirical analysis revealed the law of diminishing marginal utility of facility management. This paper contributes to the body of knowledge by extending the productivity measurement model from the construction stage only to the integration of the construction and postconstruction stages, and by offering two productivity improvement scenarios for strategy formulation. Methodologically, this paper offers a two-stage productivity measurement model and its improvement models in a mathematical way. Managerially, based on the developed models, this work offers the evidence and quantitative guidance for the policy makers and public clients to strategically improve CPP of public projects.

This paper presents developments of traditional value stream mapping (VSM) related to enhancing system and method competencies of both individuals and organisations. Since systematic immersions in traditional VSM – a highly accepted technique for improving production systems – are necessary, this paper describes from a production research point of view approaches for systematic productivity increases, reduction of lead time and an approach to improve sustainability indicators of value streams. The introduced developments of VSM focus on the entire flow and on details, thus creating synergies for designing and improving value streams, processes and work systems both economically and ecologically. On the one hand, this paper shows how practical approaches respectively rationalisation concepts (Lean principles, VSM, Process Management, short-cyclic improvement routine, Methods-Time Measurement) are used in industry in order to manage and improve processes and value streams. On the other hand, sustainability management can be supported on shop floor with utilisation of VSM. It aims to extend the view on value streams of both researchers and practitioners in sense of system and methods competencies. [ABSTRACT FROM AUTHOR]

Recently, the reverse osmosis (RO) process is widely used in the field of desalinating brackish water and seawater to produce freshwater, but the disadvantage of using this technology is the increase in the rates of electrical energy consumption necessary to manage these units. To reduce the rates of electrical energy consumption in RO desalination plants, geothermal energy and photovoltaic/thermal panels were used as preheating units to heat the feed water before entering RO desalination plants. The proposed system in this study consists of an RO desalination plant with an energy recovery device, photovoltaic/thermal panels, and a geothermal energy extraction unit. To evaluate the system performance, three incorporated models were studied and validated by previous experimental data. The results indicated that incorporating the geothermal energy and photovoltaic/thermal panels with the RO desalination plants has positive effects in terms of increasing productivity and reducing the rates of specific power consumption in RO desalination plants. The average saving in the specific power consumption for utilizing the thermal recovery system of PV panels and geothermal energy as preheating units reached 29.1% and 40.75% for the treatment of seawater and brackish water, respectively. Additionally, the economic feasibility showed the saving in the cost of freshwater produced from the RO desalination plants for incorporating both geothermal energy and photovoltaic panels with a thermal recovery system with reverse osmosis desalination plants of up to 39.6%.
