目的为减少部队弹药保障单位的储备数量和勤务时间,加快弹药保障反应速度,以托架为基础,对集装弹药进行装载优化,实现快速高效的弹药单元化保障目标,增强部队弹药机动保障、直达保障能力。方法建立弹药托架装载优化模型,提出基于启发式算法的求解思路,并给出算法步骤。结果通过算例验证了优化模型的有效性,以12种待装弹药为例,利用算法使托架的平均空间利用率达到60.25%,平均面积利用率达到89.94%。结论为解决弹药装载优化问题提供了一种技术方法,并发现标准托架与箱装弹药在设计时没有考虑互相匹配的问题,在将来托架和箱装弹药的设计中应加以考虑。 相似文献

A particular decision-making process that is needed by most firms who produce joint products is the one requiring an assessment of desirability of further processing joint products beyond the split-off point. The purpose of this paper is to develop an algorithm for optimizing a joint products further processing decision under the theory of constraints. To fit the jointly produced characteristic of joint products and the sequential produced characteristic between each joint product and its further processing product, the algorithm is composed of seven steps. These steps consider every bottleneck resource to the decision-making process by computing a priority ratio to establish its priority sequence. According to the priority sequence of the most constrained resource, the initial master production schedule is developed. Then, the following steps find the best path to reach the optimal solution under the guidance of all bottleneck resources. Due to its accessibility and comprehensibility, the TOC-based algorithm developed by this paper is a practical tool for obtaining the optimal joint products further processing decision. 相似文献

In the logistics service supply chain (LSSC), quality supervision and coordination is an important approach that can ensure the effective operation of LSSC and obtain more customers. This paper aims to study the quality decisions of the functional logistics service provider (FLSP) and the logistics service integrator (LSI) when a service quality defect guarantee is promised by the FLSP. Assuming that customer demand is a function of the quality defect guarantee of the FLSP, the optimal quality decisions of the LSI and FLSP are presented under three typical game modes: Nash game, Stackelberg game, and centralised decision. Numerical analysis is conducted to show how the quality parameters of the customer affect the optimal quality decision-making behaviour of the LSI and FLSP. The research results indicate that, under all three game modes, the optimal quality defect guarantee of the FLSP increases as the customer punishment increases, and decreases as the elasticity of the customer demand for the quality defect guarantee increases. In addition, under all three game modes, the optimal quality supervision effort of the LSI is an increasing function of both customer punishment and elasticity of the customer demand for the quality defect guarantee. 相似文献
