物流中心的规划与设计 中文摘要 本题为物流运输问题，属于有约束的线性规划模型。 本文通过对运输费用、需求量、供应量、运输方式、建设费用等因素之间关系的综合分析，建立了待建仓储选址的一般数学模型。然后我们通过对模型进行编程求解，得出物流公司的新仓储位置选择和向销售中心供货的具体方案。接着我们进行了灵敏度分析。通过对供需有小幅改变的前后数据及图表的分析，我们得出了供需小幅改变不改变选址方案，配送方案也只有小幅改变的结论，作为对物流公司的一点建设性的意见。然后我们分析了模型与实际的联系，并对模型的实际意义进行了建设性的分析，提出了有益的改进方案。最后我们对基于“供求平衡”、“供求失衡”时方案关系及模型进行了几点分析、总结，得出了一切“供需”模型均可以转化为“供求平衡”模型，我们还进行了进一步探究，提出了“供需平衡”问题的求解思路，作为对“运输问题”的一种有益的探索和有价值的总结 关键词 数学模型 物流 供需 线性规划 选址 Planning and design of logistics centers Abstract The logistics and transport issues entitled, belonging to a constrained linear programming model. Through a comprehensive analysis of the relationship between transport costs, demand, supply, transportation, construction costs and other factors, the establishment of a general mathematical model to be built warehouse siting. We then solve the model program, the company obtained a new warehouse logistics location choices and specific programs supplied to the sales center. Then we conducted a sensitivity analysis. By a slight change in supply and demand data and analysis after the chart, we have come to a slight change in supply and demand does not change the site plan, distribution plan, only a slight change in the conclusion as comments on the logistics company that constructive. Then we analyze the model and the actual contact, and the practical significance of the model had a constructive analysis, useful improvements. Finally, based on our balance supply and demand, supply and demand imbalances program relations and several models were analyzed and summarized, come all supply and demand model can be converted to balance supply and demand model, we also carried out further exploration , proposed the idea to solve the supply and demand balance, the problem, as a transportation problem a useful exploration and valuable summary.
