海上游击战的信息作战机理分析

科学地研究游击战的获胜机理是军事学领域尚未解决的核心问题之一。运用信息作战原理,在海上游击战环境中,通过潜艇与航母战斗群反潜直升机的对抗来分析海上游击战的信息作战原理,研究表明:航母受到攻击的威胁通常为潜艇的1.5到5倍,只要发挥潜艇的信息与火力的联合作战优势来削弱航空母舰战斗群的反潜信息与火力的联合作战优势,仅单艘潜艇就可对航空母舰造成重创。信息作战原理不仅揭示了游击战环境中各种小概率事件及随机因素的影响机理,而且也可用作为对游击战指挥控制原理进行研究的理论基础及方法。     

A sequential partial information bomber-defender shooting problem

A bomber carrying homogenous weapons sequentially engages ground targets capable of retaliation. Upon reaching a target, the bomber may fire a weapon at it. If the target survives the direct fire, it can either return fire or choose to hold fire (play dead). If the former occurs, the bomber is immediately made aware that the target is alive. If no return fire is seen, the true status of the target is unknown to the bomber. After the current engagement, the bomber, if still alive, can either re-engage the same target or move on to the next target in the sequence. The bomber seeks to maximize the expected cumulative damage it can inflict on the targets. We solve the perfect and partial information problems, where a target always fires back and sometimes fires back respectively using stochastic dynamic programming. The perfect information scenario yields an appealing threshold based bombing policy. Indeed, the marginal future reward is the threshold at which the control policy switches and furthermore, the threshold is monotonic decreasing with the number of weapons left with the bomber and monotonic nondecreasing with the number of targets left in the mission. For the partial information scenario, we show via a counterexample that the marginal future reward is not the threshold at which the control switches. In light of the negative result, we provide an appealing threshold based heuristic instead. Finally, we address the partial information game, where the target can choose to fire back and establish the Nash equilibrium strategies for a representative two target scenario.     

无缝GPS／INS组合导航系统的设计与实现

针对GPS卫星信号失锁条件下GPS/INS组合导航性能大幅度下降的缺点,设计了一种基于ANFIS的无缝组合导航方法,当卫星数目不低于4颗时采用伪距,伪距率的卡尔曼滤波算法,一旦卫星数目少于4颗时采用ANFIS系统估计导航误差,抑制INS的误差积累,从而实现无缝导航.动态车载实验表明,该方法切实可行,相对于传统的紧组合方法,有效地提高了组合导航系统的定位精度和抗干扰能力.     

Supply contracts in manufacturer‐retailer interactions with manufacturer‐quality and retailer effort‐induced demand

We consider a decentralized distribution channel where demand depends on the manufacturer‐chosen quality of the product and the selling effort chosen by the retailer. The cost of selling effort is private information for the retailer. We consider three different types of supply contracts in this article: price‐only contract where the manufacturer sets a wholesale price; fixed‐fee contract where manufacturer sells at marginal cost but charges a fixed (transfer) fee; and, general franchise contract where manufacturer sets a wholesale price and charges a fixed fee as well. The fixed‐fee and general franchise contracts are referred to as two‐part tariff contracts. For each contract type, we study different contract forms including individual, menu, and pooling contracts. In the analysis of the different types and forms of contracts, we show that the price only contract is dominated by the general franchise menu contract. However, the manufacturer may prefer to offer the fixed‐fee individual contract as compared to the general franchise contract when the retailer's reservation utility and degree of information asymmetry in costs are high. © 2008 Wiley Periodicals, Inc.
