基于效费比的武器目标分配

有效武器目标分配(WTA)是防空阵地的核心。分析了目标毁伤收益、武器损伤关键战术指标因素,提出基于效费比的WTA评价标准,建立了针对多目标的WTA模型,并研究了用遗传算法求解模型的方法。该遗传算法通过设计一种武器目标分配的染色体编码,利用最优保存策略选择运算、均匀交叉运算、非均匀变异运算来求解。仿真结果验证了模型的合理性和算法的有效性。     

A critical look at the U.S. deceased‐donor organ procurement and utilization system

The U.S. system for procuring and utilizing deceased‐donor organs for transplantation has been studied and written about in many articles. The purpose of this paper is to examine the interactions between the elements that comprise this system, and point out improvement opportunities that may be affected through operations research/management techniques. The authors demonstrate the need for developing data‐driven and analytic tools. In fact, data is used to generate hypotheses and support claims throughout the paper. The paper also points out the need to fully leverage data that is available to researchers, and to seek data that is currently not deposited in a centralized archive.
