Abstract: This paper aims at modeling and analyzing supply chain using TPN (Time Petri Nets). Some principles for modeling a supply chain are introduced, and a TPN based analysis method is discussed. Thus, people can optimize the use of resources both within and beyond the boundaries of enterprises, which is useful in management of electronic commerce, cooperate commerce, and virtual enterprise.
