Performance evaluation of job operation flows in computer systems by timed Petri nets

Abstract

An automatic method for computing the expected execution time of jobs based on Petri nets is proposed. With this method a job operation flow is modeled using the timed Petri net, all operation cases for every fault are considered using the reachability tree of the Petri net, and the expected execution time is computed automatically. A support system that actualizes the proposed method on a workstation is described. This approach allows job operation flows to be planned without misunderstandings.<>
