基于ExtendSim的直升机外场可更换部件需求仿真系统设计

Simulation System Design for Demand of Helicopter Line Replaceable Unit Based on ExtendSim

针对直升机外场可更换部件需求预测困难的问题,在分析直升机的使用及维修保障活动的基础上,采用了离散事件仿真方法,运用ExtendSim软件构建了模块化的维修保障仿真系统,实现了对直升机外场可更换部件需求的科学预测。该仿真系统能够为备件筹措、分配、储存、调拨等维修保障决策提供科学依据。

Aiming at the difficulty of demand forecasting for helicopter line replaceable unit,and based on the analysis of the use and maintenance support processes of helicopter,the discrete event method is used to simulate the processes.The modularization model of the maintenance support processes in the whole task phases is built using ExtendSim,and is able to forecast demand of line replaceable unit scientifically.This model can provide scientific basis for maintenance support deci sion making of raising,distribution,storage and transfer for spare parts.
