| 摘 要： | 维修费用估算是军用飞机寿命周期费用估算的重要组成部分。将三级维修体制简化为两级维修，可节省维修财力并提高战备完好性。引入灰色系统GM（1，1）模型理论，建立了转换维修体制后的财力节省预测模型，以美空军实际节省的财力数据为例进行预测，经多种精度检验表明，模型的可信性较高。

| Abstract: | Maintenance cost estimate is the important part of military aircraft LCC cost estimate. Predigesting maintenance system from level three to two level maintenance (TLM) could save maintenance cost, and improve readiness. Based on gray system GM(1,1) model theory, the cost forecast model was established for transforming maintenance system, and forecasting according to the practice save financial data of the USAAF. It was proved by multi-precision verification that the creditability of the forecast model was h... |
