【摘要】：物流在烟草行业中具有重要的地位，物流网络优化是提高烟草企业核心竞争力的有效途径之一。A卷烟公司的物流系统沿用原有计划经济的运作模式，，存在物流网络布局不合理，配送效率低等问题，导致物流成本过高。因此，A卷烟企业迫切需要改善烟草配送的物流网络。论文针对A卷烟企业的物流网络优化需求，分析了A卷烟企业物流网络优化目标、原则、企业现状、环境等重要参考因素，利用专家评价系统，初步筛选出物流配送中心备选点。建立符合烟草物流特点的物流网络优化模型，包括物流成本模型和选址决策模型，设计、开发了相应的遗传算法，求得几组相对较优解。然后，通过层次分析法将不同的影响因素分类并给出权重计算，得出了一套物流网络优化设计方案。最后，将优化后的物流设计方案，与优化前的方案在物流成本，平均年折旧，配送车辆以及人员数量方面做了对比，表明了A卷烟企业的物流网络有显著改善。
[Abstract]:Logistics plays an important role in the tobacco industry. The optimization of logistics network is one of the effective ways to improve the core competitiveness of tobacco enterprises. Distribution efficiency is low, leading to high logistics costs. Therefore, A cigarette enterprises urgently need to improve the logistics network of tobacco distribution. Aiming at the logistics network optimization demand of A cigarette enterprise, this paper analyzes the important reference factors, such as the objective, principle, current situation, environment and so on, of the logistics network optimization of A cigarette enterprise, and makes use of the expert evaluation system. Preliminary screening of logistics distribution center alternative points. The optimization model of logistics network, including logistics cost model and location decision model, was established, and the corresponding genetic algorithm was designed and developed, and several relatively optimal solutions were obtained. Then, the different influencing factors are classified and the weight is calculated by AHP, and a set of optimization design scheme of logistics network is obtained. Finally, the optimized logistics design scheme is compared with that before optimization in the aspects of logistics cost, average annual depreciation, distribution vehicles and the number of personnel. The results show that the logistics network of A cigarette enterprise has been improved significantly.
