越肩发射的研究现状和发展

越肩发射就是本机利用机载火控系统控制机载空空导弹攻击尾后敌机的一种新型的攻击方式。越肩发射分为两种发射方式:一种是导弹向前发射,在空中转弯,然后去攻击后方的目标,叫做前射;另一种是导弹直接向后发射,去攻击后方的目标,叫做“后射”,也叫“后向攻击”。从1993年越肩发射被公开报道,并引起人们的注意,至今已经11年。国内外越肩发射的研究已经取得了很多成果。介绍了目前各国越肩发射的发展情况,重点评述了各种越肩发射的实现方法,总结了目前三个研究方向的工作,即前射、后射和工程化,认为越肩发射会在导弹控制、制导律和火控系统三个方面展开工作,并展望了越肩发射研究工作的未来。

Efficient distributions of arms‐control inspection effort

A rule that constrains decision‐makers is enforced by an inspector who is supplied with a fixed level of inspection resources—inspection personnel, equipment, or time. How should the inspector distribute its inspection resources over several independent inspectees? What minimum level of resources is required to deter all violations? Optimal enforcement problems occur in many contexts; the motivating application for this study is the role of the International Atomic Energy Agency in support of the Treaty on the Non‐Proliferation of Nuclear Weapons. Using game‐theoretic models, the resource level adequate for deterrence is characterized in a two‐inspectee problem with inspections that are imperfect in the sense that violations can be missed. Detection functions, or probabilities of detecting a violation, are assumed to be increasing in inspection resources, permitting optimal allocations over inspectees to be described both in general and in special cases. When detection functions are convex, inspection effort should be concentrated on one inspectee chosen at random, but when they are concave it should be spread deterministicly over the inspectees. Our analysis provides guidance for the design of arms‐control verification operations, and implies that a priori constraints on the distribution of inspection effort can result in significant inefficiencies. © 2003 Wiley Periodicals, Inc.

Commitment decisions with partial information updating

In this paper, we extend the results of Ferguson M. Naval Research Logistics 8 . on an end‐product manufacturer's choice of when to commit to an order quantity from its parts supplier. During the supplier's lead‐time, information arrives about end‐product demand. This information reduces some of the forecast uncertainty. While the supplier must choose its production quantity of parts based on the original forecast, the manufacturer can wait to place its order from the supplier after observing the information update. We find that a manufacturer is sometimes better off with a contract requiring an early commitment to its order quantity, before the supplier commits resources. On the other hand, the supplier sometimes prefers a delayed commitment. The preferences depend upon the amount of demand uncertainty resolved by the information as well as which member of the supply chain sets the exchange price. We also show conditions where demand information updating is detrimental to both the manufacturer and the supplier. © 2005 Wiley Periodicals, Inc. Naval Research Logistics, 2005     

战场物资快速运输的指挥控制

针对战场快速物资运输的指挥控制问题,提出一种基于线性规划的方法。根据供求双方物质的供应和需求总量、地理空间上的位置以及运输工具的运载能力等信息,制订一个满足供求双方物资总运载量,并以运送所有物资耗费时间为最小的优化目标,改进了传统运输问题模型。仿真分析表明,该方法为实现战场物资快速运输的指挥控制提供了有价值的参考。
