(S-K,S)补给策略下的两级备件保障效果评估模型
|
摘要
备件是影响装备战备完好能力及任务持续能力的重要因素。考虑备件的可靠性、价格等因素,根据多级供应模式,提出了(S-K,S)备件批量补给策略。基于该策略,依据离散事件仿真原理建立了备件保障效果评估的仿真模型;利用Gamma分布的特点,建立了对应的解析近似评估模型;通过实例对模型进行了验证与对比,结果表明:两种模型的计算结果具有一致性,且当实际使用可用度高或低时,近似模型与仿真模型结果更为接近,能用于定量评估。
Spares are one of the important factors of the operational readiness and the mission success. The(S-K, S) supply strategy is proposed based on the multi-level supply mode according to spares' reliability and price. Simulation model is established to evaluate the support effectiveness of spare parts by the principle of discrete event simulation. The analytical evaluation model is also established by Gamma distribution characteristics. An approximate model is verified and compared in an example; the results show that the calculation results of the two models are consistent; and the results of approximate model are more close to the results of simulation model whether the actual availability is high or low, which can be used for quantitative assessment.
