Maintenance mission oriented number determination method of maintenance equipment for aircraft

Number identification of maintenance equipment is an emergent problem of support resources deployment for aircraft in design and development phase. Taking maintenance mission requirements as input, queuing model of batch arrival LRU (Line Replaceable Units) based on Queuing Theory is constructed. Effects of maintenance equipment failure on queuing model are analyzed. Being subjected to the constraint of average waiting time to repair, the number of maintenance equipment required is determined, which will provide a valid method to determine the number of maintenance equipment for aircraft being developed.
