Business Process Analysis of Drug Sales Management Based on Modified Petri Net

Abstract

In this paper, taking the business process of drug sales management in enterprise A as an example, a method of modified Petri net is proposed. Cost and human are introduced into the transitions of time Petri net, and time-cost-human Petri net is constructed. Then, based on the modified Petri net, cost and Manpower Capacity are introduced into the reachability tree and a "Cost and Manpower Capacity State Reachable Tree" is proposed, and a strict mathematical definition is given. The cumulative cost and Manpower Capacity of each reachable path transition sequence in Petri net can be calculated by means of the analysis method of "Cost and Manpower Capacity State Reachable Tree", thus the maximum value of cost and Manpower Capacity in the process can be obtained, and the cost and human resource performance of the business process model can be further analyzed. It makes up for the shortage of time Petri net in analyzing business process. Keywords—sales management business process; time-costhuman Petri net; Cost and Manpower Capacity State Reachable Tree
