Abstract

Sustainability in transportation is vital for lessening environmental effects and ensuring the long-term viability of the transportation industry. The aviation sector, a significant player in sustainable transport, has encountered obstacles in reducing its ecological footprint, especially in aircraft design and operation. Symmetry and asymmetry exist widely in the aviation sector, as in other industrial applications. Multicriteria decision making (MCDM) is an important research topic that is widely applied to practical decision-making problems and is considered a complex tool with which to balance the symmetry between goals and conflicting criteria. This research assesses different airplane models in order to pinpoint the most environmentally friendly options using the Bayesian best–worst (BWM) method for evaluating criteria and the consensus-based intuitionistic fuzzy evaluation based on distance from average solution (IF EDAS) method for assessing alternatives. The Bayesian BWM approach facilitates group decision making on criteria evaluation and systematically evaluates factors like fuel efficiency, emissions, and noise levels, offering a holistic view of each airplane model's sustainability performance. Conversely, consensus-based IF EDAS allows for the ranking of alternatives based on their distance to the average solution for a sustainable airplane model while concurrently considering multiple criteria, guiding decisionmakers to a consensus and eliminating the asymmetry between opinions before the final decision. This study reveals that technical features are the critical criteria for airplanes and significantly influence alternative rankings. The findings indicate that the chosen decision criteria greatly impact the selection of the most sustainable airplane model as part of a sustainable transportation system, potentially altering ranking orders.

21. An Integrated Fuzzy MCDM Method for the Evaluation of R&D Projects

Abstract

Research and development (R&D) activities are essential to guarantee continuity of firms, meet customer requirements and keep ahead in competition. R&D project selection constitutes a significant part of project management in order to achieve the desired results and outputs. In this study, an integrated fuzzy multi-criteria group decision making approach is developed for R&D project selection. The problem includes a hierarchical structure of the criteria, uncertainty in evaluating the relative importance of criteria/sub-criteria and rating of candidate projects. The method employs the ordered weighted average (OWA) operator as the aggregation operator, which helps to fully reflect the real behavior of the decision makers in group decision making problems. Fuzzy integral method, which does not require the assumption of the mutual independence of criteria, is used to rank the alternatives. The case study is conducted in a small-sized company in Turkey, which designs and produces special purpose machines. A R&D project selection model is developed to maximize the desired outputs. The results of the analysis show that technological, environmental, marketing, organizational, national and financial issues should be considered simultaneously in the evaluation process. The proposed method is shown to be efficient, generalizable and practical and it has several significant merits compared to the other methods.

32. Evaluating the Net Zero Policy Performances of European Countries Through DEA.

Author

Subjects
ENVIRONMENTAL impact analysis, CLIMATE change, GROSS domestic product
Abstract

Addressing climate change and its environmental impact is one of the greatest challenges of modern life. Most of today's sustainable strategies are essentially related to the intent of reducing overall carbon dioxide emissions. The net zero goal lays the foundation for a sustainable future. This study aims to measure the performance of European Countries based on carbon emissions. To measure performance, Pure Environmental Performance Index and Mixed Environmental Performance Index Data Envelopment Analysis (DEA) methods are used. Decision-making units (DMUs), inputs and outputs are determined. Input is identified as Primary Energy Consumption. Outputs are selected as Gross Domestic Product (GDP), Carbon dioxide (CO2) emission, Nitrous Oxide (N2O) emission. According to performance results, Albania, Lithonia, Malta, and Montenegro are classified as efficient countries via the two models. The results shows that the European Countries should take the required measures of the Paris Conference till 2050 to reduce the damage to the environment. [ABSTRACT FROM AUTHOR]

Abstract

In order to improve customer satisfaction and supply chain efficiency, supply chain management strategies began to shift toward to the first step of supply chain; which is demand planning. The automotive industry in the twenty-first century has created significant opportunities while also placing pressure on manufacturers to improve quality, improve styling, increase organizational efficiencies, and include innovative features in their products in order to attract customers and expand into new markets, thanks in large part to globalization. Because of these obstacles, car manufacturers must be adaptable and sensitive to client needs if they are to prosper. Therefore, this study focuses on demand forecasting. Demands in automotive sector in United Kingdom Market is forecasted employing multiple linear regression method. [ABSTRACT FROM AUTHOR]

Subjects
Engineering (General). Civil engineering (General), TA1-2040
Abstract

Energy is a basic need for achieving quality of life and the level of welfare. Chemical or nuclear energy are released as heat in the wake of a reaction between fuel and other substances. Heat is used for warming, cooking, or industrial processes. This paper presents an integrated multiple criteria decision making framework for fuel provider selection in food industry. Evaluation factors are named as lead time, reliability, sustainability, cost, service quality, location and warranties. To demonstrate the robustness of the application, a numerical illustration is provided by conducting a case study in food industry of Turkey.

Abstract

In project management, agility has been to deal with the shortcomings of traditional methodologies that are linear and sequential. An agile project contains both planned processes and iterations. In global competition, obtaining agile processes in outsourcing procedures allows the firms to keep up with the changes and dynamic issues. In this work, the factors that influence agile provider selection decision are evaluated, and their importance weights are determined through Decision Making Trial and Evaluation Laboratory (DEMATEL) technique. The application is illustrated through a case study, which is conducted in a white goods manufacturer that performs in Turkey. [ABSTRACT FROM AUTHOR]

Abstract

Performance management aligns individual aims with organizational aims. It is to obtain better organizational outcomes managing and understanding performance within an agreed framework of planned objectives, standards and requirements. The main elements of performance management are agreement, measurement, feedback, positive reinforcement and dialogue. The data envelopment analysis (DEA) model, also named as the CCR model, proposed by Charnes et al. (1978), computes the relative efficiency of a decision-making unit (DMU) by maximizing the ratio of its total weighted outputs to its total weighted inputs subject to the condition that the output to input ratio of every DMU be less than or equal to unity. However, conventional DEA model assigns unrealistic weights to the inputs and outputs to produce high efficiency score for the evaluated DMU and therefore the number of efficient DMUs can be quite high. To overcome that issue, common-weight DEA-based models are proposed by the scholars. In this study, performance evaluation of a technology company that performs in the retail sector is conducted and the results are analyzed. [ABSTRACT FROM AUTHOR]
