摘 要 随着社会主义市场经济的发展，作为“第三利润源泉”的物流对经济活动的影响日益明显，越来越引起了人们的重视，成为当前“最重要的竞争领域”，未来的市场竞争，物流将起着举足轻重的作用。 物流车辆优化高度，是物流中的关键环节。对货运车辆进行优化调试，可以提高物流经济效益，实现物流科学化。对物流车辆调度理论与方法进行研究，是开发车辆调度系统的基础。 本文在对国内外物流车辆调度现状及其实现技术对比的基础上，结合VRP（Vehicle Routing Problem）Hibernate在数据存取上的优势以及STRUTS在系统架构上的优势把Hibernate和STRUTS引入到物流车辆调度问题中来解决对车辆的调度问题，取得了良好的效果。并在此理论的基础之上，结合面向对象的系统分析和设计方法，设计开发出了物流车辆的调度系统。能满足中小型物流配送中心的需求。该系统对提升中小型物流企业在市场中的竞争能力具有不可低估的作用。 关健词：车辆调度；物流配送；车辆调度研究 Abstract As the development of socialist market economy, logistics being the third profit headspring has evident influence on economy activities and more and more people have been paying attention to it. Being current most important competition field, logistics will make much contribution towards the future market competition. Logistics vehicle optimization schedule is the key tache for logistics end-off (or delivery).Scheduling freight train can increase the economic profit and implement scientific logistics. The study for theory of logistics vechicle schedule is the foundation of developing delivery systems. The paper presented an approach of vehicle routing problems with VRP model,which adopts Hibernate and STRUTS based on comparison internal and overseas study status to technology for its dominance in the whole search and showed that a better result is obtained by using the approach.We designed and developed an delivery system in terms of system analysis and design method of OO(object oriented).Experimental results proved that the system can complete and satisty the delivery requirement of delivery center in time and effectively.The system will make a contribution to improving the competitive power of medium and small-sized corporations.
