In the electronic supply chain, the situation are even worse, for the characteristics ofthis supply chain: excessive lean management, global sourcing and the rather more uncertain marketdemand. E...

in this article, we estimate the vertical price transmission through the iranian rice marketing chain by usingmonthly data from march 2000 to february, 2009 and error correction model (ecm).the causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. inproducer-retail and wholesale-retail models, price transmission is asymmetric but i...

This paper describes an effort that involved development of a simulation model for evaluating the business processes and inventory control parameters of a logistics and distribution supply chain. A generic simulation tool, rather than a supply chain simulator, was developed for meeting customized needs of the effort. The paper describes the approaches used to model at the selected level of abst...

Understanding the formation of supply chain flexibility is important. We draw on the organizational learning perspective to examine how inter-organizational systems (IOS) enabled collaborative knowledge creation can enhance the supply chain flexibility. Empirical results from 141 supply chain enterprises support most of our hypotheses. The results show that, (1) IOS use for exploration has posi...

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

The main goal of the proposed model is to increase efficiency and effectiveness of the supply chain with respect to income increases and cost decreases. Using special objective funct...

The literature on the value of information sharing within a supply chain is extensive. The bulk of the literature has focused on two-level supply chains that supply a single product. However, modern supply chains often have more than two levels and supply many products. Because many of these products are variants of the same base product, they tend to be substitutes and their demands correlated...
