one of important problems in supply chains management is supplier selection. in a company, there are massive data from various departments so that extracting knowledge from the company’s data is too complicated. many researchers have solved this problem by some methods like fuzzy set theory, goal programming, multi objective programming, the liner programming, mixed integer programming, analyti...
In recent years, the green supply chain has become a key strategy for the competitiveness of organizations, where the reverse and closed-loop supply chains are one way to achieve it. In the current competitive environment, the closed-loop supply chain helps reduce costs by re-using recyclables and reducing environmental pollution by reducing waste and extending product life. In this study, a cl...
abstract regarding the imprecise or fuzzy data on the agriculture activities, applying models based on fuzzy data may be useful. in line with this condition this study tries to compare the ability of possiblistic programming approach in developing optimal solution with fuzzy and deterministic programming. to get this objective a data set obtained from 90 farmers of kohgilooye region, gathered i...
closed-loop supply chain network design is a critical issue due to its impact on both economic and environmental performances of the supply chain. in this paper, we address the problem of designing a multi-echelon, multi-product and capacitated closed-loop supply chain network. first, a mixed-integer linear programming formulation is developed to maximize the total profit. the main contribution...
This paper introduces a computational method of solving fully fuzzy multi objective linear programming problem through goal programming approach. Here we deal the imprecise parameters as fuzzy numbers with assumption that these fuzzy numbers have some possibility distribution associated with fuzzy variables. In the study, we extend the concept of conflict and non-conflict between objective func...
remanufacturing is an industrial process that makes used products reusable. remanufacturing is a way to establish a closed-loop supply chain. one of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. in addition, in this paper the researchers have tried to present a mathema...
The importance of social performance of corporate and business units has increasingly been emphasized by researchers and practitioners in recent years. Since green supply chains Play important roles in decreasing the pollution of business and corporate environments, social performance has a significant role in creating this supply chain; Therefore, in designing green supply chain social perform...
The main purpose of this paper is to develop a fuzzy multiple criteria decision-making (MCDM) model to select middle managers for the global shipping carrier-based logistics service providers (GSLPs). At first, some concepts and methods used to develop a fuzzy MCDM model are introduced. Secondly, to effectively select middle managers for GSLPs, five steps of fuzzy MCDM algorithms are proposed. ...
