Study On Integrated Optimal Allocation Model Of Maintenance Manpower And Air Material For Civil Aircraft

With the rapid development of domestic civil aviation industry in recent years,the number of civil aircraft has increased rapidly,and the maintenance engineering of civil aircraft has attracted attention.Aircraft integrated logistics support analysis is an important part of aircraft maintenance engineering,and logistics product support service is the key link of civil aircraft operation and maintenance support.In this paper,the key problem of civil aircraft maintenance engineering-the integrated optimization of logistics resources allocation for civil aircraft maintenance tasks is studied.The problem of maintenance resource allocation based on civil aircraft maintenance task is studied.The optimization of comprehensive allocation of manpower and aviation material resources in maintenance task is mainly studied and a comprehensive optimization allocation model of maintenance personnel and aviation spare parts is proposed.Aiming at the complexity and diversity of maintenance tasks in civil aircraft maintenance planning and the different maintenance capabilities of maintenance units,this method aims at maximizing the overall maintenance benefit,introduces the difficulty coefficient of maintenance personnel cooperation and coordination,discusses the influence factors of maintenance staffing on spare parts of aviation materials,and establishes a comprehensive optimization allocation model of manpower and aviation materials for maintenance tasks with time windows.On this basis,this paper improves the chromosome coding form of genetic algorithm,with the mirror binary genome coding method.In order to accelerate the convergence speed,the crossover and mutation rates in the genetic process are adaptively changed according to the changes of chromosome fitness.Finally,the feasibility of the model and algorithm is verified by simulation experiments using the maintenance data of a maintenance unit,the corresponding interactive software is designed by Graphical User Interface.This provide a certain theoretical method for the comprehensive optimization of maintenance resources allocation and global control of maintenance cost in domestic civil aviation industry.
