基于激励机制的装备采办风险总量控制

针对装备采办中的风险总量控制,提出一种激励方式来提高承包商的积极性。在单目标风险控制模型的基础上,建立了多目标风险控制模型,推导出了激励机制下风险控制的最优合同公式。对激励机制中存在的两类错误进行了理论分析和实例验证,得出了两类错误对收益的影响,并在成本控制中得到了应用,有效地提高了装备采办的质量和效率,为军方决策者在装备采办中提供了合理的参考依据。     

胶泥缓冲器的非线性阻尼的控制机理研究

为了改善履带车辆悬挂系统在各种路面的平顺性,对悬挂系统匹配了一款具有非线性特性的粘弹性胶泥缓冲器。为了定量地研究胶泥缓冲器的非线性阻尼控制机理,建立了非线性悬挂系统的动力学方程,将非线性时滞动力系统的随机最优控制规律应用于履带车辆悬挂系统,建立了车辆垂直振动加速度与车速、路况与阻尼比之间的数学关系,从理论上推导出了最佳阻尼比。最后,对履带车辆在F级和G级路面上进行了仿真分析来验证胶泥缓冲器的非线性阻尼的变化规律,结果表明,在0.07~0.18范围内调控阻尼比,可以使车体垂直振动加速度最小。该研究工作为胶泥缓冲器的优化设计和胶泥材料的配方提供了理论指导。     

目标网络分层描述与自修复机制研究?

针对目标网络分层建模与自修复机制问题展开研究。首先建立了分层次的作战目标网络模型,在此基础上提出六种维度的指标以评价作战目标网络在攻击前后能力的变化情况;其次,从预警网络层、火力网络层、指控网络层分析探索作战目标体系在遭受攻击后的最优自修复策略;最后,通过模拟攻击实验仿真分析上述自修复机制的可行性。实验结果表明该目标网络的自修复机制相比传统方法,能够更好地发挥剩余节点的作战效能。     

Supply chain coordination with shelf‐space and retail price dependent demand and heterogeneous retailers

We consider supply chain coordination in which a manufacturer supplies some product to multiple heterogeneous retailers and wishes to coordinate the supply chain via wholesale price and holding cost subsidy. The retail price is either exogenous or endogenous. The market demand is described by the market share attraction model based on all retailers'shelf‐spaces and retail prices. We obtain optimal solutions for the centralized supply chain, where the optimal retail pricing is a modified version of the well‐known cost plus pricing strategy. We further get feasible contracts for the manufacturer to coordinate the hybrid and decentralized supply chains. The manufacturer can allocate the total profit free to himself and the retail market via the wholesale price when the retail price is exogenous, but otherwise he cannot. Finally, we point out that different characteristics of the retail market are due to different powers of the manufacturer, and the more power the manufacturer has, the simpler the contract to coordinate the chain will be. © 2010 Wiley Periodicals, Inc.

Optimal operating policies in a commodity trading market with the manufacturer's presence

With the help of the Internet and express delivery at relatively low costs, trading markets have become increasingly popular as a venue to sell excess inventory and a source to obtain products at lower prices. In this article, we study the operational decisions in the presence of a trading market in a periodic‐review, finite‐horizon setting. Prices in the trading market change periodically and are determined endogenously by the demand and supply in the market. We characterize the retailers'optimal ordering and trading policies when the original manufacturer and the trading market co‐exist and retailers face fees to participate in the trading market. Comparing with the case with no trading fees, we obtain insights into the impact of trading fees and the fee structure on the retailers and the manufacturer. Further, we find that by continually staying in the market, the manufacturer may use her pricing strategies to counter‐balance the negative impact of the trading market on her profit. Finally, we extend the model to the case when retailers dynamically update their demand distribution based on demand observations in previous periods. A numerical study provides additional insights into the impact of demand updating in a trading market with the manufacturer's competition. © 2009 Wiley Periodicals, Inc.
