摘　　要： 为了节约军用自动测试设备研制经费和全寿命周期费用,提升设备快速保障能力,达到效费比最大化目标,从测试保障整体角度,分析了被测对象需求、自动测试设备费用和测试设备服役寿命,对军用测试设备的更新问题建立了基于混合整数线性规划方法更新决策模型。针对某型军用飞机测试需求,分析不同基准费用条件下测试设备的更新决策问题,对比了更新决策结果对不同影响因素的灵敏度,得到了不同服役寿命设定条件下的更新决策结果,结果表明:5~7倍单台基准费是98%被测对象对应测试设备更新决策的临界点;更新决策结果对移植费用灵敏度最高;新设备使用寿命延长到20a时,可显著影响更新决策结果。 To save the developing and whole lifetime using cost of automatic test equipment,and attain the highest cost-effectiveness ratio,from the perspective of the whole test support system,a model is established for military automatic test equipment renewal based on mixed integer linear programming,which is grounded on analysis of unit under test demand,cost of automatic test equipment and lifetime of equipment on active service into consideration.According to the needs of a certain military plane in the test,this paper analyzes the renewing decision problem under different baseline costs.Compared the influence on the sensitivities of a variety of factors from the renewed outcomes,the outcomes of different lifetimes setting are also acquired.The outcomes show that 5to 7times of baseline cost are the critical renewing points of corresponding test equipment of 98% the number of units under test,the renewing decision is mostly effected by transplanting cost,and the outcome of renewing decision is obviously affected by prolonging the lifetime of new equipment to 20 years.
