【摘要】：目前,石化企业所涉及到的非油品业务相已当广泛,其服务也日趋成熟。非油品业务的收入在整个企业利润中所占的比例也越来越大,地位越来越重要。而随着经营规模的扩大,物流配送效率低、成本高的问题一直制约着非油品经营质量的提升,并成为各大石化企业关注和重点研究的问题。本文首先介绍了国内外非油品业务的发展状况,总结了非油品物流节点布局与优化问题国内外的研究现状。然后,论述了非油品物流节点布局优化理论,在分析非油品物流节点布局影响因素的基础上,考虑配送费用、建设成本及运营费用等优化目标,结合节点的容纳能力、供应能力、平衡性等约束条件,建立了非油品物流节点布局的优化模型。针对该模型特点,对模拟植物生长算法进行了适应性的改进,利用改进后的模拟植物生长法求解该模型。最后,给出了实证分析,以西南地区重庆市为例,计算了该地区物流节点的布局方案,计算结果表明,本文所提出的非油品物流节点布局的设计方法正确、有效。本文丰富了物流节点布局理论,也为非油品物流节点布局的决策参考提供了可借鉴的方法,具有一定的理论意义和实际应用价值。
[Abstract]:At present, the petrochemical enterprises involved in the non oil business when the phase has been widely, its services are becoming more and more mature. The non oil business income in the total profits in proportion is also growing, more and more important role. But with the expansion of business scale, logistics efficiency is low, the problem of high cost has been restricted the non oil business to enhance the quality, and become the focus and focus on the large petrochemical enterprise. This paper first introduces the development status of non oil business at home and abroad, summarizes the research status of domestic and foreign non oil logistics node layout and optimization problem. Then, discusses the non oil logistics node layout in optimization theory. Analysis of the factors affecting the non oil logistics node layout, considering the distribution cost, construction cost and operation cost as optimization objective, binding capacity, node supply capacity, balance constraints, An optimization model of non oil logistics node layout. According to the characteristics of the model, the plant growth simulation algorithm of adaptive improvement method to solve the model by using plant growth simulation improved. Finally, gives an empirical analysis to the southwest of Chongqing city as an example, the layout scheme of logistics nodes in this area are calculated. The calculation results show that the design method of non oil logistics node layout proposed in this paper are right and effective. This paper enriches the logistics node layout theory, but also provides a reference method for the non oil logistics node layout of the reference, has certain theoretical significance and practical value.
