Research On Optimization Problem Of Training Fleet Composition For Pilot Training School

With the rapid growth of air transportation production in volume,the number and scale of pilot training schools are significantly developing with the prosperity of airlines' demands for pilot human resource.Determining which types and number of training airplanes to introduce and to properly use for pilot training movements is one of the important strategic decision contents for enhancing the training safety and benefit of a pilot training school.Furthermore,this is also a vital way to resolve the bottleneck of pilot human resource in airline industry.One of the kernels of solving this problem is to find a rational methodology,in which the number and types of training airplanes for various level-based aircraft types must be accurately predicted.This kind of a methodology is also particularly important for various pilot training schools,airlines and civil aviation administration government departments.From the perspective of pilot training schools,this article attempts to present a methodology to forecast the number and types of training airplanes,and eventually aims to develop a system optimization methodology.The following two aspects are focused.(1)A comprehensive evaluation analysis of selecting training airplane's type.It uses a multi-level comprehensive evaluation framework.First,an indicator system of impacting the selection of training airplanes is presented.Second,three numbers in one interval is used to express indicators with the uncertainty characteristics in results.Finally,the entropy-weight TOPSIS(a simplified called on Technique for Order Preference by Similarity to an Ideal Solution)is employed to construct the training airplane selection model.Four primary-level training airplane types are used to verify the accurateness of the proposed model.The results show the model's feasibility.(2)An integrated model of optimizing the training airplanes' composition and their deployments to the training bases.According to CCAR 61 and CCAR 141,the pilot training process is abstracted to a weighted and directed graph by two dimensions of pilot training stage and training base.Then several limitations including the total number of aviation training students,the flowing balance conditions,the available flying hours of training fleetand the least number of deployed training airplanes on each training base are considered as constraints,an integrated model of optimizing fleet composition and its base deployment problem is constructed with objective of minimizing the total fleet training costs.A simulated analysis on a certain example in China is used to verify the feasibility of the proposed model.The results show the model could reduce the number and types of training airplanes,and decrease the types of training airplanes deployed to training bases.The training costs of training fleet could also significantly reduced.
