维修任务调度的多目标决策模型

通过对维修调度问题进行分析,考虑到战斗力相关的多种目标因素,针对目前研究的目标单一,又未考虑武器的先进程度、配置等缺陷,就修复后的加权作战时间和装备尽可能少的延误数量双重目标加以研究,并给出了调度算法。从而弥补了这些缺陷,使调度更加合理。最后,算例表明模型的求解方法简单,计算时间较短,可有效地实现维修任务调度。     

Resale price maintenance contracts with retailer sales effort: Effect of flexibility and competition

In Resale Price Maintenance (RPM) contracts, the manufacturer specifies the resale price that retailers must charge to consumers. We study the role of using a RPM contract in a market where demand is influenced by retailer sales effort. First, it is well known that RPM alone does not provide incentive for the retailer to use adequate sales effort and some form of quantity fixing may be needed to achieve channel coordination. However, when the market potential of the product is uncertain, RPM with quantity fixing is a rigid contract form. We propose and study a variety of RPM contracts with quantity fixing that offer different forms of flexibility including pricing flexibility and quantity flexibility. Second, we address a long‐time debate in both academia and practice on whether RPM is anti‐competitive in a market when two retailers compete on both price and sales effort. We show that depending on the relative intensity of price competition and sales effort competition, RPM may lead to higher or lower retail prices compared to a two‐part tariff contract, which specifies a wholesale price and a fixed fee. Further, the impact of RPM on price competition and sales effort competition is always opposite to each other. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2006

航天器编队飞行构形保持与重构的继电型控制

研究小偏心参考轨道航天器编队飞行构形保持与重构控制的工程实现技术。首先给出相对运动状态转移矩阵,并推导出常推力控制情况下相对运动状态递推的解析表达式;进而给出脉冲推力、连续变推力和继电型推力三种发动机的推力模型和示意图。分别将等速度冲量的三种推力模型代入相对运动状态转移矩阵中,比较相同条件下相对运动控制作用效果的差异,理论推导结果表明:在一阶意义上,三种推力模型对相对运动控制作用等效,因而航天器编队构形保持与重构控制可以基于继电型推力模型来实现。     

The Organization of the Defense Support System: An Economic Geography Perspective

In the context of restricted budgetary resources and the growing cost of maintenance, repair, and overhaul (MRO) activities, a major issue for modern armed forces is to sustain defense platforms. A possible method consists of realizing economies of scale through the concentration of maintenance activities, which involves the spatial reorganization of existing industrial sites dedicated to MRO. This article provides a formalized framework to discuss the optimal organization for the MRO of defense platforms in space. The public planner organizes the maintenance of defense platforms with only two possible spatial configurations. In the dispersed configuration, two industrial production units in charge of the maintenance optimally cover space, whereas in the concentrated configuration, a unique industrial unit covers space. Focusing on the tipping point between the two configurations, the balance of forces between agglomeration and dispersion in defense support activities is described and discussed. On the one hand, economies of scale provide an opportunity to optimize defense support costs, favoring concentration in a unique industrial unit. On the other hand, space causes dispersion to reduce both transport costs and operational social costs. This trade-off illustrates a general principle in spatial economics with an application to MRO production in the French case.
