【摘要】：随着全球烟叶市场竞争的加剧，烟草企业对烟叶生产持续稳定发展提出了更高的要求。国家烟草局明确烟叶生产以“市场引导，计划种植”为指导的方针政策，主要体现在烟草企业与烟叶生产区烟农种植户签订烟叶购销合同，按烟叶计划进行种植并对其进行回购。烟叶生产物流作为烟草企业供应链的起始点，烟叶生产区物流网点的合理规划布局对整个烟叶生产的持续稳定发展起着至关重要的作用，然而目前烟叶生产区物流网点布局的研究还很少。因此，论文对烟叶生产物流网点布局的研究探索具有重要的理论和实际意义。首先，根据国家局对烟叶生产区布局规划的基本要求，，利用物流网点布局优化的理论和方法，结合烟叶生产区物流网点布局的特点和现状，分析影响烟叶生产物流网点布局的因素。其次，在建立烟叶生产物流网点布局优化模型时，从烟叶生产物流网点布局问题界定中确定规模估测、网点选址、辖区范围这三个布局优化问题作为切入点分别提出优化方法。在规模优化问题中运用物流量预测方法和网点数量估算方法；在网点布局选址优化问题中利用选址模型和MATLAB软件；在网点辖区范围确定问题中提出基于道路网络距离的Voronoi图方法来实现各点的管辖覆盖范围。再次，以重庆H区烟叶生产物流网点布局为例，结合重庆烟草公司对烟叶生产区布局规划的基本要求，应用提出的网点布局优化方法和模型对H区烟叶生产区物流网点的规模、选址及辖区覆盖范围进了布局优化，并对H区烟叶生产区布局优化结果从经济效益和社会效益两个方面进行评价。最后，得出论文的结论：（1）建立烟叶生产物流网点布局优化的规模模型、选址模型、辖区覆盖范围模型，达到规划布局整体最优、经济效益和社会效率最优目的。（2）以H烟叶生产区物流网点布局优化为例，根据布局化的模型获得该区以“1+12”共计13个网点配置规模和各个烟草点辖区覆盖范围的确定。
[Abstract]:With the increasing competition in the global tobacco market, tobacco enterprises have put forward higher requirements for the sustained and stable development of tobacco production. It is mainly reflected in the signing of tobacco purchase and marketing contract between tobacco enterprises and tobacco farmers in the tobacco production area, planting and repurchase according to the tobacco leaf plan, and the tobacco production logistics as the starting point of the supply chain of tobacco enterprises. The rational planning and layout of the logistics network in the tobacco production area plays a vital role in the sustainable and stable development of the whole tobacco production. However, there is little research on the distribution of the logistics network in the tobacco production area at present. This paper has important theoretical and practical significance for the research of distribution of tobacco production logistics network. First of all, according to the basic requirements of the State Bureau on the layout planning of tobacco production areas, and using the theory and method of logistics network layout optimization, combined with the characteristics and current situation of tobacco production area logistics network layout, The factors influencing the distribution of tobacco production logistics network are analyzed. Secondly, when the optimization model of tobacco production logistics network layout is established, the scale estimation and site selection are determined from the definition of tobacco production logistics network layout. The three layout optimization problems in the area of jurisdiction are used as the starting point to put forward the optimization methods respectively. In the scale optimization problem, the method of forecasting the material flow and the number of nodes are used, the location model and the MATLAB software are used in the optimization of the location of the network layout. In the problem of determining the scope of network area, the Voronoi diagram method based on road network distance is put forward to realize the coverage of each point. Thirdly, taking the distribution of tobacco production logistics network in H district of Chongqing as an example, According to the basic requirements of Chongqing Tobacco Company on the layout planning of tobacco production area, the scale, location and coverage of the logistics network in the production area of H area were optimized by the proposed method and model. The optimization results of tobacco production area in H area were evaluated from two aspects: economic benefit and social benefit. Finally, the conclusion of the paper is: 1) to establish the scale model, location model, area coverage model of tobacco production logistics network layout optimization, so as to achieve the overall optimal planning layout. The optimal objective of economic and social efficiency is to optimize the distribution of logistics network in H tobacco production area. According to the model of distribution, the allocation scale of 13 outlets and the coverage range of each tobacco site in this area are determined by the model of "112".
