supplier selection is one of the most important activities of purchasing departments. this importance is increased even more by new strategies in a supply chain, because of the key role suppliers perform in terms of quality, costs and services which affect the outcome in the buyer’s company. supplier selection is a multiple criteria decision making problem in which the objectives are not equall...

Enterprise-wide supply chain planning problems inherently exhibit multi-level decision network structures, where for example, one level may correspond to a local plant control/scheduling/planning problem and another level to a plant-wide planning/distribution network problem. Such multi-level decision network structures can be mathematically represented using multi-level mathematical programmin...

Reverse supply chain is a process dealing with the backward flows of used/damaged products or materials. Reverse supply chain includes activities such as collection, inspection, reprocess, disposal and redistribution. A well-organized reverse supply chain can provide important advantages such as economic and environmental ones. In this study, we propose a general framework and formulate a m...

The complexity of the inter-organizational collaboration processes is one of the main concerns of the supply chain management. SCOR (Supply Chain Operation References) process reference model addresses those concerns by providing a process implementation roadmap, consisting of workflows, best practices, systems and performance metrics. In this paper, we use SCOR framework to develop knowledge-b...

Consider a multi-channel supply chain (hereafter SC) system, producing and distributing two substitutable products. Within this framework, we study the SC efficiency by comparing several decentralized SC configurations with a centralized one. Our result show that it is often possible to achieve 93.5% or more of the total profit of a centralized SC in a decentralized configuration, which suggest...

the health industry’s supply chain is full of uncertainty and unpredictability. thus, building an intelligent system to effectively capture the requirements of customers and help manage the supply chain is very important. despite artificial intelligence widespread acceptance as a decision-aid tool, ai has seen limited application in supply chain management. to fully exploit the potential benefi...

during recent years, determining appropriate strategy in the supply chain has become an important strategic issue. however, the nature of these decisions usually is complex and unstructured. to determine the best supply chain strategy, many quantitative and qualitative attributes such as cost, responsiveness and flexibility can be taken into account. in order to approximate the human subjective...

Supply chain management has gained renewed interest among researchers in recent years. This is primarily due to the availability of timely information across the various stages of the supply chain, and therefore the need to effectively utilize the information for improved performance. Although information plays a major role in effective functioning of supply chains, there is a paucity of studie...

Supply chain management (SCM) is a subject that has found so much attention among different commercial and industrial organizations due to competing environment of products. Therefore, integration of constituent element of this chain is a great deal. This paper proposes a multi objective production-allocation and distribution planning problem (PADPP) in a multi echelon supply chain network. We ...
