The inventory cost is a primary component of the supply chain cost, and the method for multi-echelon inventory optimization and control must be adopted for the sake of the entire supply chain optimization and control, t present, papers on multi-echelon inventory systems have solved some problems, but they still have limitations. Firstly, they assumed that leadtime are constants. In practice, as the unknowable incidents exist in production, transportation and distribution processes, leadtime usually are uncertain. Secondly, there exist the hypotheses of totally back orders or completely lost sales under the condition of stockout in most literatures. Thirdly, the existing two-echelon inventory approximate model optimum always fixes one variable in the inventory strategy, and then seeks the optimal in the remained parameters, which makes the result can not be the best outcome.
目前有关两级库存优化控制的研究文献大多是假设提前期为常数的基础上建立模型,然而现实中由于供应链上各节点的库存不确定性以及运输、生产、交货等环节的不可预知性,使得提前期在多数情况下是不确定的;而且大部分文献都是假设缺货情况下要么完全延迟交货,要么完全损失销售,很少有考虑部分损失销售情况下库存优化控制的;另外,现有的两级库存近似模型的优化大都是固定一个库存策略中的变量,对余下变量寻优,其优化结果不可能是最优结果。

This paper has done a deeply research on the evaluative method, which focus on maintaining and ensuring the camion. After deeply analyzing the maintain theory of army equipment and the stratagem 's characteristic and combining the current systems engineering evaluating theories and methods, it has analyzed and solved all limitations that coming forth when a single model is used to evaluate the maintain capacity. After analyzing and ameliorating the judgment of AHP's coherence, the calculation of the expert power value and the optimizing of the more-extreme judging model, a new calculation method, the multidimensional complex calculation theory, is presented, which much fits for the evaluative calculation of the camion. The new theory's feasibility and the evaluation's reliability have been proved in theory in this paper. This paper also analyses the principle and the program, which is about building a camion evaluating system. According to the multidimensional complex calculation theory, an evaluative model has been built. Applying the levels analytical method, this paper fixes on the calculation of every target's power, brings the optimization allot precept of macro spatial resource, optimizes the resource of the maintainability of theater of operations' vehicle, which offers a theory foundation for optimizing of the resource space. The research not only brings out a uniform standard for the evaluating of the maintain ability of the camion, but also presents a theory foundation and method for perfecting the camion maintain system.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
