Petri network-based chemical leakage event emergency disposal process performance analysis method

Abstract

The invention discloses a Petri network-based chemical leakage event emergency disposal process performance analysis method. The method comprises the steps of 1) analyzing emergency tasks involved ina chemical leakage event emergency disposal process and associated time information and resource information; 2) performing formalized modeling on the whole emergency disposal process of the chemicalleakage event based on a Petri network; 3) under the condition of not considering resource factors, analyzing the time performance based on a Petri net model of a chemical leakage event emergency disposal process; 4) under the condition of considering resource factors, proposing a detection algorithm of potential resource conflicts; and 5) proposing a conflict resolution strategy based on the taskpriority, and analyzing the time performance of the emergency disposal process of the chemical leakage event after the strategy is applied. According to the invention, a conflict detection method anda strategy for eliminating resource conflicts are provided and applied to model construction of the emergency disposal process of the chemical leakage events, and actual application of time performance analysis of the emergency disposal process of the chemical leakage events is promoted.

Description

technical field [0001] The invention relates to the technical field of business process management, in particular to a Petri net-based method for analyzing the performance of an emergency disposal process for chemical leakage events. Background technique [0002] As an effective tool for modeling and analysis of discrete event systems, Petri nets are widely used in dealing with system concurrency and conflict problems. Therefore, Petri nets are also widely used in modeling, analysis, control and verification of workflow systems. , and the use of Petri net to model workflow has three advantages: 1. Petri net is a graphical language and has accurate semantic definition; 2. Petri net is based on state events, so the model based on Petri net can be detailed 3. The property analysis methods of Petri nets have been deeply studied, and these methods can be directly applied to actual projects. However, the existing workflow modeling and analysis methods cannot It is directly used t...
