Firms developing new products must often make a trade-o¤ between production costs and product quality: higher quality products are more valued by consumers, but also more costly to manufacture. We analyze this trade-o¤ in the context of demand uncertainty and strategic consumer behavior. Before the release of a product to a heterogeneous market of unknown size, a …rm must choose product quality...

spurred by intensifying competition in global markets, most companies have been increasingly implementing supply chain management (scm) and information systems (is) practices. as well, globalization policies have created a more intensive competition amongst manufacturers; in additional the priority of supply over demand, market competition and importance of some factor such as quality, accounta...

Networks provide the physical and information structure of systems for transporting all food, water, people, information and goods within our modern life. Emergency Management (EM) organizations need to have highly functioning logistics networks as key towards supporting and aiding affected populations in disasters or conflicts. Optimization has made immense strides towards improving logistics ...

The paper presents a yield optimizing scheduling system (YOSS) in a decentralized supply chain management (DSCM) environment. For this purpose we employ a DSCM scenario in which each supplier, provides system parts by order of one or more customers. The supplier tries to optimize its return by searching the optimal schedule for the single machine he uses to manufacture the requested products. T...

The coordination problem of relief items’ distribution operations is essential in humanitarian relief chains. If the coordination is proper, it will improve the response phase to the crisis. In order to improve the coordination in humanitarian relief chains, distribution and warehousing operations of relief items were outsourced to the third-party logistics.

This paper describes how the new international standard series IEC 61850 is applied and extended to meet the requirements for almost the whole electrical energy supply chain, especially outside substations. Several activities are under way in the domains of power generation (wind power plants, hydro power plants, and decentralized energy resources), power transmission and distribution as well a...

This paper describes the impact of two different information sharing strategies – decentralized and centralized information – combined with two inventory control policies – min-max and stock-to-demand inventory control – on the bullwhip effect. To investigate and measure this impact, simulation models are developed using the Arena 5.0 software package for a four-stage supply chain, consisting o...
