The rapid advancements of Information Communications Technology (ICT) are leading to extreme improvements in computing power and to the design and development of innovative products and new improved versions of the existing ones. As a result, ICT products become obsolete more quickly and in increased quantities resulting to ever-increasing waste of electrical and electronic equipment (e-waste)....

Building a strong supply chain is essential for business success. But when it comes to improving their supply chains, few companies take the right approach. Many businesses work to make their chains faster or more cost-effective, assuming that those steps are the keys to competitive advantage. To the contrary: Supply chains that focus on speed and costs tend to deteriorate over time. The author...

in this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified. providing a measure for bullwhip effect that enables us to analyze and reduce this phenomenon in supply chains with two products is the basic purpose of this paper. demand of products is presented by the first order vector autoregr...

We overview some of the major advances in supply chains and transportation networks, with a focus on their common theoretical frameworks and underlying behavioral principles. We emphasize that the foundations of supply chains as network systems can be found in the regional science and spatial economics literature. In addition, transportation network concepts, models, and accompanying methodolog...

This study considers pricing, production and transportation decisions in a Stackelberg game between three-stage, multi-product, multi-source and single-period supply chains called leader and follower. These chains consist of; manufacturers, distribution centers (DCs) and retailers. Competition type is horizontal and SC vs. SC. The retailers in two chains try to maximize their profit through pri...

Evaluating the performance of supply chains is a difficult task due to the complexity inherent to the size and the structure of the supply chain. This paper presents a framework for evaluating and providing approximate dimensioning for supply chains. The framework is based on Data Envelopment Analysis (DEA) as a dynamic tool for measuring the relative technical, pure technical and scale efficie...

Firms are increasingly embracing integrated Web-based or e-supply chains because such chains are believed to enhance efficiency and competitiveness. The e-supply chain movement has received a boost from a variety of off-the-shelf supply chain software solutions that have appeared on the market. However, in the excitement about these software solutions, it is often overlooked that creation and i...
