Approximation algorithms for general one‐warehouse multi‐retailer systems

Logistical planning problems are complicated in practice because planners have to deal with the challenges of demand planning and supply replenishment, while taking into account the issues of (i) inventory perishability and storage charges, (ii) management of backlog and/or lost sales, and (iii) cost saving opportunities due to economies of scale in order replenishment and transportation. It is therefore not surprising that many logistical planning problems are computationally difficult, and finding a good solution to these problems necessitates the development of many ad hoc algorithmic procedures to address various features of the planning problems. In this article, we identify simple conditions and structural properties associated with these logistical planning problems in which the warehouse is managed as a cross‐docking facility. Despite the nonlinear cost structures in the problems, we show that a solution that is within ε‐optimality can be obtained by solving a related piece‐wise linear concave cost multi‐commodity network flow problem. An immediate consequence of this result is that certain classes of logistical planning problems can be approximated by a factor of (1 + ε) in polynomial time. This significantly improves upon the results found in literature for these classes of problems. We also show that the piece‐wise linear concave cost network flow problem can be approximated to within a logarithmic factor via a large scale linear programming relaxation. We use polymatroidal constraints to capture the piece‐wise concavity feature of the cost functions. This gives rise to a unified and generic LP‐based approach for a large class of complicated logistical planning problems. © 2009 Wiley Periodicals, Inc. Naval Research Logistics, 2009

作战油料需求预计不确定性因素及误差分析

当前各种油料需求预计单纯地追求表面精确而忽视实有误差,重静止轻动态,脱离了作战保障实际。从技术、勤务和战术结合的层面,将油料需求预计不确定性因素归结为油料消耗标准本身、计划与实际运用差异、影响油耗的自然因素考虑不同、作战任务理解判断差别四点,并对各自的误差范围进行了粗略分析。提出的不确定性因素及误差范围界定,有助于引发人们对作战油料需求预计新的思考,提高油料勤务理论研究和实践能力水平。

Beyond Just War: Military Strategy for the Common Good

The objective of this article is to move ethical discourse on military strategy beyond the confines of the established War Convention. This is achieved by utilising the common good, a concept found in political philosophy and theology. The common good acts as a positive organising concept for socio-political activity. With its focus on peace, development and the flourishing of the individual and community, the common good poses a significant challenge to strategy. This article constructs an approach to strategy that is compatible with the common good. Importantly, it does so whilst respecting the pursuit of victory as an indispensable component of strategy’s true nature. The theory presented in this article is then tested in relation to four different modes of strategy: regular war, irregular war, deterrence, and cyberwar.
