The present study implements a generic methodology for describing and analyzing demand supply networks, that is, networks from a company’s suppliers to its customers. There can be many possible demand supply networks with different logistics costs for a product. Therefore, we introduce a Petri Net-based formalism, and a reachability analysis based algorithm that finds the optimum demand supply ...

We model a real-world case problem as a price competition model between two leader-follower supply chains that each of them consists of one manufacturer and one retailer. T he manufacturer produces partially differentiated products and sells to market through his retailer. The retailer sells the products of manufacturer to market by adding some values to the product and gains margin as a fracti...

this study deals with a two-level supply chain consisting of one manufacturer and one retailer. we consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. the retailer receives product and conducts a 100% inspection....

A key challenge in operations management is how to effectively design a supply chain structure that is in alignment with the company’s business model. The supply chain management literature provides a number of techniques and guidelines for developing effective supply chain strategies. Fisher’s (1997) famous article profoundly influenced the literature by suggesting a framework which matches pr...

The aim of this study is to propose a new model of the extended supply chain where design of new products is integrated into the process of designing the supply chain. The paper deals with a recent approach that tackles the product and the supply chain design issues at the same time and proposes a methodology of an optimal design of the product and its extended supply chain. We also propose UML...
