夺取心理优势的谋略运用

心理战是信息化条件下一种重要的作战样式,围绕双方心理优势的"角逐"将贯穿整个作战始终。"实则虚之,引敌上钩"、"虚则实之,慑敌妄动"、"虚则虚之,惑敌为实"、"实则实之,引敌为虚"、"虚实结合,迷敌心智"等谋略运用将是夺取"心理优势"的重要途径。

Optimal empty vehicle redistribution for hub‐and‐spoke transportation systems

This article considers the empty vehicle redistribution problem in a hub‐and‐spoke transportation system, with random demands and stochastic transportation times. An event‐driven model is formulated, which yields the implicit optimal control policy. Based on the analytical results for two‐depot systems, a dynamic decomposition procedure is presented which produces a near‐optimal policy with linear computational complexity in terms of the number of spokes. The resulting policy has the same asymptotic behavior as that of the optimal policy. It is found that the threshold‐type control policy is not usually optimal in such systems. The results are illustrated through small‐scale numerical examples. Through simulation the robustness of the dynamic decomposition policy is tested using a variety of scenarios: more spokes, more vehicles, different combinations of distribution types for the empty vehicle travel times and loaded vehicle arrivals. This shows that the dynamic decomposition policy is significantly better than a heuristics policy in all scenarios and appears to be robust to the assumptions of the distribution types. © 2008 Wiley Periodicals, Inc.

刘少奇与三线建设的历史回顾和思考

在20世纪60年代中期开展的三线建设中,刘少奇作为中共中央副主席、中华人民共和国主席,在三个方面作出重要贡献:一是努力建立中苏两党、两国团结关系,争取有利于中国经济建设的良好外部环境;二是研究制定了以备战为中心的第三个五年计划,提出三线建设要控制基本建设规模;三是主持召开中央政治局一系列会议,指导实施三线建设计划.
