Configurationmodelofpartial repairablesparesunder batch ordering policy based on inventory state

Rational planning of spares configuration project is an effective approach to improve equipment availability as well as reduce life cycle cost （LCC）. With an analysis of various impacts on support system, the spares demand rate forecast model is constructed. According to systemic analysis method, spares support effectiveness evaluation indicators system is built, and then, initial spares configuration and optimization method is researched. To the issue of discarding and con-sumption for incomplete repairable items, its expected backorders function is approximated by Laplace demand distribution. Combining the （s-1, s） and （R, Q） inventory policy, the spares resup-ply model is established under the batch ordering policy based on inventory state, and the optimi-zation analysis flow for spares configuration is proposed. Through application on shipborne equipment spares configuration, the given scenarios are analyzed under two constraint targets：one is the support effectiveness, and the other is the spares cost. Analysis reveals that the result is consistent with practical regulation;therefore, the model＇s correctness, method＇s validity as well as optimization project＇s rationality are proved to a certain extent.     

Dynamic airspace configuration method based on a weighted graph model

This paper proposes a new method for dynamic airspace configuration based on a weighted graph model. The method begins with the construction of an undirected graph for the given airspace, where the vertices represent those key points such as airports, waypoints, and the edges represent those air routes. Those vertices are used as the sites of Voronoi diagram, which divides the airspace into units called as cells. Then, aircraft counts of both each cell and of each air-route are computed. Thus, by assigning both the vertices and the edges with those aircraft counts, a weighted graph model comes into being. Accordingly the airspace configuration problem is described as a weighted graph partitioning problem. Then, the problem is solved by a graph partitioning algorithm, which is a mixture of general weighted graph cuts algorithm, an optimal dynamic load balancing algorithm and a heuristic algorithm. After the cuts algorithm partitions the model into sub-graphs, the load balancing algorithm together with the heuristic algorithm transfers aircraft counts to balance workload among sub-graphs. Lastly, airspace configuration is completed by determining the sector boundaries. The simulation result shows that the designed sectors satisfy not only workload balancing condition, but also the constraints such as convexity, connectivity, as well as minimum distance constraint.

针对航天器柔性结构动态和静态变形控制的作动器布局关键问题,提出了一种综合优化配置方法。首先,基于有限元分析方法建立结构和压电作动器的模型。然后,基于可控Gramian矩阵提出了一种新的动态变形控制准则,并以形面均方根误差(RMSE)作为静态变形控制的优化准则。改进NSGA-II遗传算法的交叉和变异算子,以动/静态变形控制准则为目标,获得作动器综合优化配置Pareto最优解集。最后,提出归一化加权方法进行最优解集的综合筛选。最后,文章以一大型抛物柱面天线的支撑桁架为例,通过仿真验证了综合优化配置方法的优越性,其优化配置结果兼顾了动态变形控制和静态变形控制的性能。

排队论与整数规划：转场背景下对A机场旅客检查人员配置的考察

机场旅检工作人员工作模式相对特殊，实行上一休二的倒班模式，本文通过调研A机场Y航站楼转场前后连续3天的出港旅客到达率情况，并结合前人研究，利用排队论M/M/c和整数规划模型对A机场目前的旅检工作人员配置情况进行分析，发现A机场存在较大的人力资源浪费现象，特别是每天出港航班波峰期之外，人力资源浪费更加明显。本文对旅检人员配置提出两种优化方案，首先，在保证旅客服务质量符合民航局要求的前提下，利用模型测算出每个时段需要开放的最小安检通道数量；其次，提出上一休二与上五休二的综合排班模式，对旅检人员配置做更进一步的优化，实现配置效用最大化。
