Secondly , according to some well - known design principles such as loose coupling , reusability and easy - maintenance , this thesis developed a design specification based on uml ( unified modeling language ) 为了实现apln - pddss ,本文本着松耦合、可重用、易维护的基于构件的设计原则,运用uml对物资调运决策支持系统进行分析与设计。
According to the material supply of xiaowan hydroelectric project , the author presents the three - hierarchy notional model and discusses the mathematical model and algorithm for material stocking and dispatching , which is used in the decision support system for material dispatching 摘要根据小湾水电工程物资供应管理的实际情况，提出了物资调运的三级节点概念模型，论述了物资采购与调运的数学模型，并给出了具体算法。
At the point of analyzing the coal transport market , transport means , and the main coal ports , the author specified the market competition which qinhuangdao port faced . based on the whole descriptions of coal transport demands and consumes , we introduced the model of goods distribution and made some analysis about some main coal ports . and through analyzing those aspects we got a whole evaluation of the qinhuangdao port and brought out some realizable measures to the future development , such as : applying the theory of market subdividing , keeping the market share and dealing the consignees " join and developing the straight transport , setting up the center of coal gathering and distributing and dealing , intensifying the management of company , improving the port synthetical ability , fasting the construction of port basic facilities and work the coal transport well 作者以分析煤炭运输市场、运输方式和主要的煤炭运输港口为着眼点，具体分析了秦皇岛港所面临的市场竞争形势；通过对煤炭产地和消费地分布的描述，介绍了煤炭运输需求和消费的总体概况；并引入物资调运模型对主要港口之间的煤炭运量分配进行了简单的定量分析；综合以上分析，对秦皇岛港的现状作出整体评价，提出了切实可行的未来发展对策，即：应用市场细分理论；保住市场分额，做好货主衔接，发展直达运输；建立煤炭集散交易中心；强化企业管理，提高港口综合能力；加快港口基础设施建设，搞好煤炭运输生产经营等。
Apln - pddss ( physical distribution decision support system based on armed police logistics network ) is a special decision - making tool set designed for armed police , it ' s used to optimize physical distribution process by decision - making model . this thesis discusses issues concerning design and implementation of apln - pddss . firstly , based on analysis in tendency of military logistics , researches in logistics network and requirements of armed police , this thesis present the architecture of apln - pddss 本文深入分析了国内外军事物流的发展趋势和军事物流网络的现状,分析了武警物流网络物资调运决策的现状和需求,在此基础上,提出了武警物流网络物资调运决策支持系统( apln - pddss )的总体框架。
