Purchasing Process is the upstream part of a Supply Chain System. This paper proposes the modeling and performance evaluation of a Hospital Purchasing Process using Stochastic Petri Nets (SPN). SPN is a special type of Petri Nets, with timed transitions, whose firing time is exponentially distributed. The purchasing process is a “mix” of 2 hospital purchasing processes, in order to perform comprehensive simulation, using PIPEv4 Petri Net software. The simulation results and the calculated performance indices can be used to improve the purchasing process.

摘要

Purchasing Process is the upstream part of a Supply Chain System. This paper proposes the modeling and performance evaluation of a Hospital Purchasing Process using Stochastic Petri Nets (SPN). SPN is a special type of Petri Nets, with timed transitions, whose firing time is exponentially distributed. The purchasing process is a “mix” of 2 hospital purchasing processes, in order to perform comprehensive simulation, using PIPEv4 Petri Net software. The simulation results and the calculated performance indices can be used to improve the purchasing process.
