基于险度函数的无人机备件库存量风险损失度量

针对无人机备件库存量风险可能产生的潜在损失,在分析比较各种风险度量方法的基础上,利用险度函数构建了一种新的用于定量分析无人机备件库存量风险损失的函数模型,确立了模型满足险度函数的条件(线性风险度量公理系统),探讨了行为人在定常风险偏好特性和可变风险偏好特性时任意一型备件潜在损失的计算方法。最后,对3个仓库的无人机某型备件库存量风险进行了仿真实验。算例验证了函数模型合理有效,为各种仓储方案风险评估提供了量化参考。

Inventory risk loss measurement of spare parts on UAV based on risk measurement function

To deal with the potential losses of inventory risk about unmanned aerial vehicle(UAV)spare parts,risk measurement function was used to set up new function model of UAV spare parts used for quantification analysis,and the conditions of risk measurement function(linear risk measure axioms)given,and the calculation method of the potential losses with behavior having constant risk preference and diversifying risk preference presented,based on the analysis and comparison of all types of relevant risk measurement methods.Finally,simulation experiment was carried out concerning inventory risk of a certain type of UAV spare parts from three warehouses.The calculation example was presented to show that function model is rational and efficient,and can provide quantitative reference for risk evaluation of various storage scheme.
