Abstract
To solve the impact of node enterprise behavior's uncertainty on supply chain system's performance, a stochastic analysis method for node enterprise behavior of supply chain by using Pi-calculus method was proposed. Interactive diagram was used to describe the uncertainty of node enterprise behavior. Through building the mapping relationship between interactive diagram and Pi-calculus, the Pi-calculus formal specification of node enterprise behavior was acquired. With the operational semantic rule of Pi-calculus, the state transition diagram of node enterprise behavior was formed, which was corresponded to a homogeneous Markov chain. The theory of Markov chain was applied to conduct quantitative analysis on randomness of node enterprise behavior. It was found that the relative impact of customer orders operation's success rate in overall supply chain was determined by order processing capability of each node enterprise. The simulation experiments showed that the proposed method could evaluate the node enterprises with maximum impact on supply chain operations, thus guide improvement of supply chain's operational efficiency.
