国外战储法规建设及启示

为贯彻落实依法治军、依法治储要求,推动战备物资储备工作法治化,提高我军战备物资储备法规体系建设的科学化水平,本文探讨了加强战备物资储备法规体系建设的必要性,深入分析了美国、日本、俄罗斯战储法规制度建设情况以及立法特点、实践经验。结合我军战储建设实际,借鉴他国的立法思路,在法规体系建设上提出基于立法规划、法规制订、立法研究、立法队伍建设等方面的措施建议,对建立适应我军新的编制体制和战储建设实际的法规制度具有重要作用。     

Determining optimal sizes of bounded batches with rejection via quadratic min‐cost flow

In this article, we consider a single machine scheduling problem, in which identical jobs are split into batches of bounded sizes. For each batch, it is allowed to produce less jobs than a given upper bound, that is, some jobs in a batch can be rejected, in which case a penalty is paid for each rejected job. The objective function is the sum of several components, including the sum of the completion times, total delivery cost, and total rejection cost. We reduce this problem to a min‐cost flow problem with a convex quadratic function and adapt Tamir's algorithm for its solution. © 2017 Wiley Periodicals, Inc.

面向能力需求的武器装备组合规划模型与算法

针对武器装备组合规划中存在的选择难、规划难问题,在给定能力需求的条件下,从分析装备的组合变更对整体体系的影响出发,考虑了总的经费预算、年度费用分配、装备规划周期等约束,以能力差距和发展风险最小为准则,构建了双目标优化模型,并设计了基于差分进化和非支配排序的遗传算法的求解算法,获得模型的Pareto解。通过逼近理想解排序法方法从所求Pareto解中求得令决策者满意的折中解。通过一个具体示例验证了模型和算法的有效性,能够为武器装备组合规划提供辅助决策。

论按要素分配与按劳分配

十六大明确了新的分配原则即“生产要素按贡献参与分配原则”,这是我国收入分配理论和政策方面的革命性突破。弄清楚这一原则的确切含义、实施原因、分配形式、实现途径以及它与按劳分配之间的关系,对充分调动社会各方面的积极性,优化资源配置,切实保障广大群众的切身利益有着十分重大的意义。     

The one‐warehouse multiretailer problem with an order‐up‐to level inventory policy

We consider a two‐level system in which a warehouse manages the inventories of multiple retailers. Each retailer employs an order‐up‐to level inventory policy over T periods and faces an external demand which is dynamic and known. A retailer's inventory should be raised to its maximum limit when replenished. The problem is to jointly decide on replenishment times and quantities of warehouse and retailers so as to minimize the total costs in the system. Unlike the case in the single level lot‐sizing problem, we cannot assume that the initial inventory will be zero without loss of generality. We propose a strong mixed integer program formulation for the problem with zero and nonzero initial inventories at the warehouse. The strong formulation for the zero initial inventory case has only T binary variables and represents the convex hull of the feasible region of the problem when there is only one retailer. Computational results with a state‐of‐the art solver reveal that our formulations are very effective in solving large‐size instances to optimality. © 2010 Wiley Periodicals, Inc.
