Abstract:

In order to adjust and optimize resources in communication equipment maintenance support system,according DEVS(Discrete EVent System Specifications) and time petri net theory, a model for communication equipment maintenance support system based on hierarch structure is established. A model for communication equipment maintenance support system based on HTPN(Hierarchy Time Petri Net) is established. The method which applied complex place and sub-Petri net conquered to the shortage of modeling of communication equipment system based on Petri net, the model becomes directly perceptible and simple and is fit to be analyzed and simulated. The model can be used to analyze the shortest time for equipment maintenance. At last the application of the model is discussed. This conclusion can provide the decision-maker of equipment maintenance with support and also can improve the ability of equipment maintenance with support.

Key words: hierarchy time petri net（HTPN）, maintenance support system, discrete-event, model
