对技术成熟度评价应用于装备预研的若干问题分析

TRL(Technology Readiness Level)评价是用以评价某项特定技术的成熟程度,以及比较不同技术的成熟程度的系统性、定量化工具,其对象是装备研制的关键技术,目的是把握技术成熟状况、工程化决策支持以及装备研制技术风险管理。推广使用这项工具,就是希望通过TRL评价,能够准确把握装备预研攻关的进展情况和技术状态,综合分析存在的问题和差距,为提高装备预研的科学决策和项目管理水平提供支撑。立足于TRL评价在装备预研中的实际应用场景,本课题针对TRL评价的适用性,工作结构分解(WBS)与项目技术分解之间关系、关键技术遴选原则和关键技术评价细则四个难点问题进行了讨论,以期回答如何使TRL评价这项工具在实际应用中能得以更好运用的问题。

War as a System: A Three-Stage Model for the Development of Clausewitz’s Thinking on Military Conflict and Its Constraints

This article presents a new model for the development of Carl von Clausewitz’s thinking on the factors that constrain warfare. The model posits three stages in his thinking that are determined by two system theoretic dimensions. The three stages are friction as a constraint on the effectiveness of the execution of military plans on paper, suspension as a constraint on the intensity of military action and political objectives as a constraint on military objectives. The two dimensions consist of an interactive perspective in the form of causal feedback loops and a holistic perspective in the form of a political system that forms the context of the military subsystem.     

How should modeling and simulation be used to support defense acquisition?

This paper investigates the potential for modeling and simulation to contribute to new defense system development, by increasing the productivity of traditional R&D in developing system‐specific technology. Building on a previous optimal control model of defense system R&D, it shows that (1) the optimal use of modeling is related in a natural way to that of traditional R&D, and (2) both have similar optimal profiles over time. Simulated results based on limited historical data suggest that optimal use of modeling could increase the rate of growth in system‐specific technology significantly.     

Asymptotic analysis of periodic policies for the inventory routing problem

In this article, a distribution system is studied where the sum of transportation and inventory costs is to be minimized. The inventory holding cost is assumed to be the same for all retailers. A fixed partition (FP) periodic policy is proposed with tight asymptotic worst‐case performance of 3/2 with respect to the best possible policy. This bound cannot be improved in the class of FP periodic policies. In partition‐based PB policies, the retailers are first partitioned into sets and then the sets are grouped in such a way that sets of retailers within a group are served together at selected times. A PB periodic, policy is presented with tight worst‐case asymptotic performance of with respect to the best possible policy. This latter performance improves the worst‐case asymptotic performance of of the previously best known policy for this problem. We also show that the proposed PB periodic policy has the best worst‐case asymptotic performance within the class of PB policies. Finally, practical heuristics inspired by the analyzed policies are designed and tested. The asymptotic worst–case performances of the heuristics are shown to be the same of those of the analyzed policies. Computational results show that the heuristics suggested are less than 6.4% on average from a lower bound on the optimal cost when 50 or more retailers are involved. © 2013 Wiley Periodicals, Inc.
