Developing a Model for Measuring Severity of Effects Caused by Interconnected Units in Electronic Supply Chains.

For many electronic supply chain networks in the world that can comprise hundreds of companies with several tiers of suppliers and intermediate customers, there are numerous presenting risks to consider. In the electronic supply chain, the situation are even worse, for the characteristics of this supply chain: excessive lean management, global sourcing and the rather more uncertain market demand. Electronic companies are forced to manage their supply chains effectively to increase efficiency and reactivity. This paper proposes a mathematical model for estimating the severity of interactions between supply chain’s units and how their affect on the entire supply chain. Based on the model, scholars can model supply chains easily with considering interconnected units. Basic characteristics of supply chains are considered in the model. The units, which are used to simulate the members of supply chains, produce appropriate products by intelligent choices. The relationships on units are connected by their activities ; then, the proposed model is applied to an experimental example. The model yields its numerical parameters and responses by means of Lingo software.
