Coordinated dynamic control of marketing and production

We study the dynamic profit maximization problem for a firm exercising control on both marketing and production. The firs marketing effort impacts the current‐period demand, which in turn affects future demand in a dissipating fashion. Under linear‐cost and zero‐leadtime assumptions, we show that the firm should follow base‐point rules for both marketing and production, whereas trends of the base points reflect a certain complementarity between marketing and production. We obtain comparable results when marketing costs are convex. Our computational study identifies conditions under which simple fixed‐marketing‐effort and fixed‐marketing‐target heuristics would perform well. © 2009 Wiley Periodicals, Inc.

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

基于CAS理论的装备保障系统结构优化研究

信息化条件下联合作战装备保障系统是一个复杂系统。采用传统的还原论的方法难以实现对该系统进行优化。以复杂系统理论作为指导，采用自底向上的方法建立了联合作战装备保障系统的多主体计算机模型。以机步师山地进攻陆空联合作战装备保障为例，对比分析了装备保障系统层次结构和完全自组织结构的优缺点，证明了以复杂系统理论分析、优化装备保障系统结构是可行的。
