1、I 百源木业有限公司配送线路优化方案的研究与设计 摘要 高效率合理的配送是物流系统 顺利运行的保证， 配送线路安排的合理与否对配送速度、成本、效益影 响很大 。正确合理地安排车辆的配送线路， 实现合理 的 线路运输，可以有效地 节约运 输时间， 增加车辆 利用率，从而降低运输成本， 提高 企业 经济效益 与客户服务水平， 使企业 达到科学化的物流管理 , 这 也是企业提高自身竞争力的有效途径之一 。 物流配送路径优化问题 具 有很高的计算复杂性，属于 NP 完全难问题，高效的精确算法存在的可能性不大 ，但可根据启发算法求得近似最优解 。 本文首先对物流配送进行概述，然后以婺源百源木业有限公司的

2、配送 方案 为 例 ，对百源木业有限公司的配送现状进行分析，并运用节约算法、扫描算法以及改进后的最近插入法对百源木业有限公司的配送线路进行优化，提出最优配送方案。 关键词 配送 车辆路径问题 节约算 法 扫描算法 改进的最近插入法 II Research and Designation of optimization of Baiyuan Wood Co., Ltd. distribution line Abstract Reasonable and efficient distribution is the insurance of a smooth running logistics sy

3、stem； distribution line arrangement is reasonable or not has a great influence on the speed of delivery, costs and benefits. To arrange a reasonable and correct delivery line for vehicle and achieve a reasonable transport line can effectively increase the utilization of vehicles, save transportation

4、 time, thus reducing transportation costs, improving economic efficiency, enhancing customer service levels and enable enterprises to achieve scientific logistics management, which is one of the effective way for an enterprise to improve its competitiveness. The optimization of logistics distributio

5、n routing which has high computational complexity is a NP-hard problem, that is why efficient exact algorithm is unlikely to exist. In the beginning of this paper is an overview of logistics and distribution, and then take Wuyuan Baiyuan Wood Co., Ltd. distribution as an example to analysis of the s

6、tatus of its distribution, and use saving algorithm, scanning algorithm and the improved method has recently inserted to optimize the distribution lines for Wuyuan Baiyuan Wood Co., and at last, propose the best distribution scheme.
