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 ofcompanies with several tiers of suppliers and intermediate customers, there are numerous presentingrisks to consider. 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. electronic companies are forced to manage their supply chains effectively to increase efficiencyand reactivity. this paper proposes a mathematical model for estimating the severity of interactionsbetween 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 ofsupply chains are considered in the model. the units, which are used to simulate the members of supplychains, produce appropriate products by intelligent choices. the relationships on units are connected bytheir activities ; then, the proposed model is applied to an experimental example. the model yields itsnumerical parameters and responses by means of lingo software.
