Learning curves have been frequently applied in production/operations management and various logistics processes in many manufacturing and service organizations. However, studies on their integral use in the supply chain are recent. This paper contributes to filling this knowledge gap by measuring the impact of learning on lead time in logistics management systems. The empirical study was used as a methodological tool to demonstrate this. The logarithmic-linear models, with their terminology and calculation equations, were applied to three case studies representatives of the logistics systems proposed by the Supply Chain Operations Reference (SCOR) model: make-to-order, make-to-stock, and engineer-to-order. As a result, the first two were adjusted to the Stanford model and the third to De Jong's model. Their learning curve, mathematical equations, and a sensitivity analysis were determined. This approach demonstrated its relevance and difference compared to previous publications, which mainly analyze links or parts of the CS. [ABSTRACT FROM AUTHOR]

Biomass for energy generation is an attractive alternative to reduce dependence on fossil fuels and their environmental impact. Thus, the geographical location of the production and consumption sites, logistics, as well as the planning of the supply chain are crucial factors for the assessment and implementation of bioenergy projects. Although several studies have addressed these problems separately, there are few papers that integrate all these aspects. This study focuses on the integration of geographic information systems, transport modelling, and transportation costs optimization through the use of a web platform to determine biomass production and consumption sites for energy purposes. Through a case study and the analysis of different supply and demand scenarios, the operation of the optimization module is evaluated. The results allow optimally estimating the distribution of biomass from different supply centers (storage nodes), towards different users (demand nodes), taking the cost of transport as an objective function. The optimal distribution of biomass allows planning its use for different regions of interest at the national level. [ABSTRACT FROM AUTHOR]

Nowadays, stock management became a strategic decision used by organizations due to the high impact it has on the overall performance of supply chains. This paper evaluates the impact of the implementation of a R, S inventory policy in the finances of a distribution network. The research involves the functioning of a hardware supply chain conformed by a retailer and a manufacturer, which is simulated trough system dynamics. The main results of the study validate the positive impact that the policy about network liquidity have. Likewise, it is possible to determine the dominance of parameters such as demand, the review period and the maximum production capacity over the overall performance of the system.

This paper studies the levels of competitiveness and productivity of the Metalworking Sector of the city of Barranquilla, based on the design of an evaluation model for the supply chain of companies belonging to that sector. The model consists of five critical aspects: supply, storage, inventory management, distribution and transport, and reverse logistics. These factors include a set of variables that evaluate the planning, execution, measurement, and control of supply chain management. The model was validated in five companies of the Metalworking Sector of the city of Barranquilla. Solutions for integral logistics practices were established in the procurement processes, taking into account quality standards of processes and security of the supply chain. It is concluded that the sector has presented a great economic growth in the country and it is necessary the optimization and continuous improvement of the productive processes through the monitoring and control of appropriate indicators.

There are many tools to model the business processes of a supply chain (SC). However, they have a high degree of complexity that makes difficult the concatenation between conceptualization, structuring, and design. Colored Petri-Nets (CPN) is a powerful tool for modeling and specification of complex systems; however, these are still in a stage of development. This paper presents a methodology that integrates the capabilities of modeling, simulation, and analysis of the business processes of a SC with the purpose of reducing the complexity of modeling and analyzing results. The results obtained explain the levels of utilization of the resources; likewise, through the properties of the CPN, the behavior of the textile SC as a whole could be known. [ABSTRACT FROM AUTHOR]

This paper presents a Methodology of Inventory Management that determines the levels of integration and cooperation in a supply chain, so that policies and joint actions to improve the performance of the actors in the chain strategies are generated. It defined the five steps to implement collaborative planning between actors in the supply chain and integration of processes within the same processes as well as indicators to measure their performance as a result of a monitoring strategy. The methodology is validated in Wood sector companies of the city of Barranquilla, where weaknesses are evident in inventory management because they have not adopted best practices for managing inventories collaboratively between actors from different levels Supply Chain. The results show low levels of integration of inventory management processes within companies, which is the result of poor collaboration and integration process between actors from different levels of the supply chain of wood and furniture, allowing to define strategies to improve inventory management among companies that comprise it.

It is known the contribution of SMEs in the economy as well as its management problems. One solution is the use of performance metrics in order to quantitatively understand their behavior. For this purpose, is really helpful the operations reference model (SCOR) designed by the Supply Chain Council. The research methodology of this paper presents a mixed approach with a non-experimental method, whose design is descriptive transversal. The aim is to define the different parts that make up the SCOR model for metalworking SMEs from Olavarria, Argentina, in order to identify the supply chain and category of each process, as well as define indicators and best practices for each conFig. tion. The sector has been divided into four subgroups and it was found that all of them work with design products, except of the manufacturing of aluminum apertures that also makes customized products and stock products [ABSTRACT FROM AUTHOR]

The province of Chimborazo, in Ecuador, has optimal characteristics for planting and harvesting coffee plantations, such as: altitude, temperature, relative humidity, wind, topography, physical-chemical characteristics; known as high altitude coffee. The objective of the research is analysis of the circular supply chain in the coffee sector in the Lugmapata farm. The article is carried out under a quantitative approach for the use of documentary techniques and methods, which includes a bibliographic review of the state of the art and the analysis in the supply chain of circular economy variables. A plan was obtained to improve the position of the farm and the brand in the market. [ABSTRACT FROM AUTHOR]

The challenge of using renewable energy sources means that the production of biofuels and the design of their supply chains, should be pursue environmental and social benefits beyond the purely economic benefit. In this paper are revised some discussions about the impact of biofuels on sustainability and researching in the biofuel supply chains design of first and second generation via mathematical optimization, to analyze how environmental and social concerns have been considered in this problem. Finally, techniques most used optimization were identified and the review found that the concept of sustainability in the design of biofuel supply chains through modeling, is just beginning.
