1、精选优质文档-倾情为你奉上基于.Net的邮政速递物流线路管理系统 王浩霖专心-专注-专业目录绪论邮政产业是我国经济社会发展的基础和保障，其兴衰和安全与否关系着我国各方面发展的安全。经过长时期的政策管制和市场发展，我国的邮递产业已经逐渐成熟，形成了投资主体多元化的竞争格局。但是由于能源资源的不断消耗，邮政速递市场的开放，经济危机的冲击以及政策倾向的减退，邮政速递面临巨大的危机和挑战，并存的还有更大的机遇。邮政速递要应对多变、竞争激烈的市场环境，并保持市场占有率和利润率，就必须从自身的经营建设中寻找突破，加强成本管理，提高效率。作为整个快递链末端的二次配送，就为企业提高核心竞争力，降低成本提供了一
2、个很好的突破口。当前快递企业成二次配送存在很多的缺点，比如物流意识淡薄，物流人才短缺，配送节点布局不合理，信息化水平低等，直接制约了销售企业的发展。快递二次配送处于产业链末端，它的改革变动并不对产业链的其余重要部分产生较大的影响，而且，对二次配送的优化早已在很多速递企业中展开。其中不乏成功的、典型的案例，可以在一定程度上指导理论，为继续开展和深化快递二次配送优化提供经验和方案。另外，运筹学等学科以及先进技术、管理手段的应用也为邮件配送优化提供了理论基础和手段。实践证明，快递二次配送优化项目的实施，不仅能够促使运输线路优化、配送结构优化、库存优化，降低了成本，为销售企业带来了巨大的利润，并且节省
3、了配送时间，提高了服务质量，消费者的满意度大大提高。因此，开展并深化速递配送优化已经成为了当前各大速递公司降低成本、提高利润的一个重要手段。中国邮政的优势在于网点众多，且深入二三线城市，只有依靠企业自身的优势并充分利用国内国外环境中的有利方面，克服困难，提高成邮件配送的效率，降低配送的成本，增加配送的满意度，才能在竞争日益激烈的速递物流市场提高自身企业的核心竞争力，最终从市场中脱颖而出，做行业的佼佼者和领头羊。关键字：线路规划、降低成本、快递配送效率、核心竞争力AbstractPostal industry is the basis of our economic and social dev

16、编写Web程序比起以前的网页编写方式可谓是一场革命。ASP.NET可以使用.NET平台快速方便的部署三层结构。ASP.NET革命性的变化是在Web页面中使用基于事件的处理，可以指定处理的后台代码文件，可以使用C # ,VB ,J # 作为后台代码语言。.NET中可以方便地实现组件的装配，后台代码通过命名控件可以方便地使用自己定义的组件。表示层放在ASPX页面中，数据库操作和逻辑层用类来实现，这样就很方便地实现了三层结构。“三层结构”指的是逻辑上的三层，而非物理上的三层结构。第一层表示层，即Web浏览器。在表示层中包含系统的显示逻辑，位于客户端。其任务是由Web浏览器向网络上的某一Web服务器提出服务请求，We
