Abstract:

Aiming at the problem of maintenance support resources allocation for aircraft in grass-roots level, an allocation method of maintenance support resources based on hierarchical timed colored Petri net (HTCPN) is proposed. Firstly, according to the content and process of aircraft maintenance support work in grass-roots level, the HTCPN simulation model of the whole process of aircraft maintenance support is constructed by using CPN Tools software, and a method of simulation clock conversion is designed. Secondly, the rule for the maintenance support resources allocation is proposed, and the model of maintenance support resources allocation based on the sortie rate of aircraft is established. Finally, the results of numerical example analysis show that the proposed method can quickly and accurately complete the allocation of maintenance support resources for aircraft in grass-roots level. The proposed method provides technical support for the scientific formulation of aircraft maintenance support allocation in grass-roots level, and has definite value to engineering application.

Key words: maintenance support, resource allocation, hierarchical timed colored Petri net (HTCPN)
