21、agricultural product logistics distribution center will help the healthy and Orderly development of logistics industryThe rapid industrialization and growth of many countries around the world has spurred the development of supply chains management reach around the world. Supply chain management is t

22、he management which increases the value of supply chain. It is the process of plan, moderateness and control among departments and organizations in the whole supply chain to the flow of goods, information and capital etc. Its purpose is to maximize net value and increase operational efficiency and e

23、ffectiveness to all related process through system optimization.Supply chain management is the high stage of logistics development, which provide opportunities for manufacturers to cut costs and be closer to emerging and high growth markets but it has also created new risks. As supply chains become

24、more and more dependent on the efficient of logistics center in supply chain have great influence to the modern logistics. It play an important role in making use of logistic resources, upgrading logistics technology and logistics equipment, improving quality of service, improving logistics investme

25、nt environment, promoting the growth of the third party logistics provider. In addition, the site selection of logistics distribution center is an important part of logistics planning, and the quality of site selection program has a directly influence to service cost and scope of the whole logistics

26、 system.Our model is a variant of the standard fixed charge capacitated facility location models with several sources; which has the same constraints but uses a non-linear objective function to capture the operational aspects of lead times and service level explicitly. As site selection of logistics

27、 distribution center is a discrete combinatorial optimization problem. In this paper, we discuss the use of genetic algorithms (GA) for solving the site selection problem. The advantage of GA is that their chromosomes representations depend on the constraints and not the objective function. Thus, by

28、 modifying only the fitness function, we can use a given representation to develop GA to optimize different objectives under the same constraints. Site selection of logistics distribution centers is a kind of NP hard problem When the number of vendors and delivers crease，the complexity of the proble

29、m grows in the form of exponential At the process of site selection，this paper consider the factors among vendors，dealers，distribution centers and the optimization problems under supply chain management etc and design me solution model and test the model with mat lab at last At present， the theoreti

However, this paper simplifie

31、s the cost of delivery path, the impact of certain storage management strategy and administrative measures to site selection of distribution centers are not considered too, etc. Those problems are all the focus in our future study.The iron and steel industry has enormous logistics components; it is

32、under constant pressure to shorten delivery time, improve quality, reduce cost, and improve service. Therefore, how to control the logistics costs under the existing condition is the urgent problem for the iron and steel enterprises.In recent years, many researchers have conducted studies on Logisti

33、cs Cost Management. For cost control of iron and steel enterprises, these studies mainly took the viewpoint of production logistics and production techniques.As present, the logistics cost control of small and medium-sized iron and steel enterprises mainly have the following major problems:In order

34、to prevent interruption of the supply of raw materials, the enterprises overstock raw material and work in progress.The inventory of raw materials, semi-finished products, and purchased components is determined according to stock requirement, rather than driven by the orders books.After decades of d

35、evelopment, production logistics situation has become more complicated. It has brought more and more challenges to the day-to-day business operation and planning of the enterprises.We assume that the production capacity of enterprises can fully meet the needs of the market; the location and sales vo

According to the logistics center location model in (2),the longitude and latitude coordinates are calculated as(105.7,26.5). Thus, the logistics center is to be built at Longquan in Chengdu. In 2006, CW Group Corpor

38、ation has developed a complete logistics distribution map, established a database of its distributed inventory, rationalized the companys external transportation routes, optimized the flow of goods and materials, continued to reduce the rate of empty vehicles and improved efficiency, integrated the

39、logistics resources in Lianjie, Zizhong, Longquan, Xichang, and Chongqing, and optimized the logistics transportation costs.Based on the concept of a logistics center, the corporation has formed integrated logistics infrastructure using Longquan as the center, and projecting its capability to as far

It has achieved a logistics operating revenue of 277 million Yuan (RMB) and a profit of 12.5 million Yuan in 2006. The third-party logistics group has achieved a 1.75 mill

41、ion Yuan revenue outside the corporation.This paper establishes a logistics center location model to optimize the enterprises logistics network and reduce inventory and transportation costs.This paper also provides a case study, showing that this method can effectively enhance the logistics cost con

43、运输条件。物流配送中心的选址应接近交通运输枢纽，使配送中心形成物流过程中的一个恰当的结点。在有条件的情况下，配送中心应尽可能靠近铁路货运站、港口及公路。（3）用地条件。物流配送中心的占地问题在土地日益昂贵的今天显得越来越重要。是利用现有的土地，还是重新征地？地价如何？是否符合政府规划要求等等，在建设配送中心时都要进行综合考虑。 （4）商品流动。企业生产的消费品随着人口的转移而变化，应据此更好地为企业的配送系统定位。同时，工业产品市场也会转移变化，为了确定原材料和半成品等商品的流动变化情况，在进行物流配送中心的选址时，应考虑有关商品流动的具体情况。 （5）其他因素。如劳动力、运输与服务的方便程度

44、、投资额的限制等。 如何降低物流成本，提高适应能力和应变能力是一个配送中心，农产品物流配送中心，重点研究的问题。目前，对物流的研究集中了最经济的物流成本的直接因素理论分析，解决了在高物流问题的成本主要由直接通道解决方案。这项研究对配送中心如何选址的观点来讲，分析了定位的配送中心物流成本的影响。并找到一种简单的，容易被定位的一种方法账面上，通过计算机模拟的配送中心选址分析及应用，因此对农业产品的物流配送中心的位置。才能实现科学，合理，这将达到降低物流成本的目标，并作出决定。决策支持功能到物流设施和农业产品规划。 农产品物流配送和客户有数十甚至数百个每天和交易中心的交易是在高频率。如果配送中心是远

45、离其他经销点，移动和材料运输和业务数据采集不便，成本高。在现代化建设中的农产品物流配送中心是一个复杂的工程系统，不仅涉及具体的战略定位和商业模式指定的物流技术，信息技术，而且还物流管理理念和方法，对于构建基本的分布中心。如何降低物流成本，提高适应能力和应变能力是一个配送中心，农产品物流配送中心，重点研究的问题。所谓物流成本是指在货物移动过程中的人力，物力，财力的支出总和。如装卸，搬运，运输，储存，流通，加工，信息处理等领域。总之，物流成本是完成所有物流活动的费用。和降低物流责任成本不仅依赖于物流节，但也对“经营策略”，以一个伟大的供应链连锁经营，降低总的物流配送中心的成本是连锁超市的大力支持“

46、利润“。连锁超市公司的物流成本在发达国家大部分费用冷库分布（包括冷藏冷冻）为2.5倍，常温储存，如果物流成本特别注意的是不支付给物流配送中心的成本会计，它会给企业带来严重的后果。 在农产品物流配送中心的最佳位置应位于通过上述计算机模拟分析附近的“河园”，它是从每题5分运输成本最低的位置。有许多不确定因素很难在实际应用中测量，它可以通过调整运输解决。这个位置可以基本满足需求。他对模型的应用程序的关键是准确的地图取代，这是不难作出的实际物流图，可能涉及数十甚至数百个分销点，电脑使用方法将是非常宝贵的。理论上讲，虽然它的精度有一定的误差相对于传统的定位方法依赖于主观意见.它是比较科学的，此外，上面提

47、到的方法简明，没有先进的计算机编程技术是必要的，具有一定的电脑知识，只要和操作技能，任何人都可以完成它，也很容易申请到国外物流经验，实践表明，农产品物流配送中心的正确位置将有助于物流业的健康有序发展。快速工业化和世界各地的许多国家的增长刺激了对供应链管理的发展达到世界各地。供应链管理是管理这增加了供应链的价值。这是规划，适度和部门之间以及在整个供应链的货物流通组织控制过程中，信息和资金等，其目的是最大限度地增加净值，通过系统的运作效率和效力的所有相关流程优化。供应链管理是物流的发展，这为制造商提供机会，降低成本并更贴近新兴市场和高增长市场，而且它也创造了新的风险较高的阶段。由于供应链变得越来越

48、多的物流中心在供应链效率有很大的影响力依赖于现代物流业。发挥它在使后勤资源，提升物流技术和物流设备，提高服务质量，改善物流投资环境，促进第三方物流供应商发展的重要作用。此外，物流配送中心选址是物流规划的重要组成部分，而选址方案的质量有直接影响服务的成本和整个物流系统的范围。我们的模型是一个标准的固定设施的能力受限与数位模型充电源变体;它具有同样的限制，但使用非线性目标函数来捕捉交货期和服务水平的明确的业务方面。作为站点的物流配送中心选址是一个离散组合优化问题。在本论文中，我们讨论选址问题解决了（GA）的遗传算法的使用。了遗传算法的优点是，他们的染色体陈述的约束和目标函数不依赖。因此，只有通过修

49、改的健身功能，我们可以使用一个给定的代表性GA的发展相同的约束下，优化不同的目标。网站的物流配送中心选址是一个NP难问题的一种。当供应商的数量和提供的折痕，这个问题的复杂性的增加的指数形式。在选址过程中，本文考虑厂商之间的因素，经销商，分销中心和供应链管理下的优化等我解决问题和设计模型和测试，最后用垫实验室模型。目前，理论研究和实际应用的优化问题是相对的选址系统少在我整个供应链管理。因此，本文提出的模型和测试问题的实践与GA它有一个研究中心的意义。然而，本文简化了传递路径的成本，某些存储管理战略和行政措施的影响配送中心的工地，不考虑太多的选择，等等这些问题都是我们今后研究的重点。钢铁行业已经部分巨大的物流，它的压力下不断缩短交货期，提高质量，降低成本，提高服务的。因此，如何控制现有条件下的物流成本是钢铁企业亟待解决的问题：1、近年来，许多研究人员进行物流成本管理的研究。出于成本的钢铁企业的控制，这些研究主要是采取了生产物流和生产技术的观点。 至于目前，小型和中
