【摘要】：随着时代的发展和思想观念的进步，采购管理成为供应链管理中最具有价值的部分而获得企业和学术界的重视。电子商务已经给当前的时代留下了深深的烙印。传统的采购模式已经不能满足当前企业生存和发展的需要，此时集中采购模式应运而生，成为当前电子商务中的一大亮点。当前大型企业或者政府单位可以拥有自己的集中采购系统，这样他们可以做到实现规模效益，节约采购成本，推进采购队伍的专业化建设，有利于企业目标的实现。而更多的中小公司对集中采购模式却是有心无力，但是第三方采购公司它可以为中小企业提供采购服务，它可以通过接受足够的订单，汇总客户的需求，，通过数量的优势来获得供应商的折扣。对于第三方采购公司来说，如何获得最大的利润则是他们所要考虑的，当面对单种商品需求的情况下，选择最佳的供应商还比较容易，但是面对多种商品需求和多家供应商的情况下，如何得到最佳的选择成为了一个复杂的问题。由于对于某种商品的各家供应商提供的优惠条件可能不同，所以得到的结果更加不确定。此时需要采用一种算法来帮助公司进行选择，从而解决公司的困难。本文是开发一个钢材集中采购平台，公司通过自己的业务活动而获得订单，并根据自己的供应商管理和选择体系进行集中采购，在保证供应商提供产品的质量的同时获得更好的折扣，从而增加自身实力，更好的为客户进行服务。系统开发采用了.NET技术，采用WinForm的开发框架还有Visual Studio2010开发工具、SQLServer2005数据库软件和UML建模工具。在供应商选择阶段，利用改进的遗传算法，在多供应商多产品组合选择的问题上为企业提出一个良好的解决方案。
[Abstract]:With the development of the times and the progress of ideas, Procurement management has become the most valuable part of supply chain management, which has attracted the attention of enterprises and academia. Electronic commerce has left a deep mark on the current era. The traditional procurement model can no longer meet the needs of current enterprises. The need for survival and development of the industry, At this time, the centralized procurement model emerged as the times require, becoming a bright spot in the current electronic commerce. At present, large enterprises or government units can have their own centralized procurement systems, so that they can achieve economies of scale, save procurement costs, and promote the professionalization of procurement teams. While more small and medium-sized companies are powerless on the centralized procurement model, third-party procurement companies can provide procurement services to small and medium-sized enterprises by accepting sufficient orders. Aggregate customer needs and obtain supplier discounts through quantitative advantages. For third-party purchasing companies, how to make the most profit is what they have to consider, and it is easier to choose the best supplier when it comes to the demand for a single commodity. But in the face of multiple commodity demands and multiple suppliers, the question of how to get the best choice becomes a complex one, since the preferential terms offered to each supplier of a commodity may differ. Therefore, the result is more uncertain. An algorithm is needed to help the company choose to solve the company's difficulties. This article is to develop a steel centralized procurement platform, the company through their own business activities to obtain orders, and according to their own supplier management and selection system for centralized procurement, While ensuring the quality of the products, the suppliers can get better discounts, so as to increase their own strength and better serve their customers. The system development adopts .NET technology. Using WinForm development framework, Visual Studio2010 development tool SQL Server 2005 database software and UML modeling tool. In the stage of supplier selection, using improved genetic algorithm, Put forward a good solution to the problem of multi-supplier and multi-product combination selection.
