Modeling the Supply Chain Disruptions: A Study based on the Supply Chain Interdependencies

Abstract

With the advent of globalization, the number of geographically dispersed firms through the global supply chain increased. The partnership between those firms contributed to the supply chain interdependence among different levels of the supply chain. In a positive way, the interdependence of the supply chains encourages all players of the supply chains to engage in planning, forecasting, replenishment, information sharing, resource sharing and incentive sharing. In a negative way, if a disruption happens in any point of the chain and the firm doesn't have any contingence plan, the disruption effect easily propagates and amplifies through the others in the chain. In this sense, the supply chain interdependence must be modeled for a better understanding. Therefore, this paper has the aim to model the supply chain interdependence through the combination of Inoperability Input-output Modeling (IIM) and Petri net (PN) technique. From that point, it was created a place node and a transition node. One example demonstrated the proposed place-transition Petri net class, where it is more generic and easy to apply technique.
