【摘要】 虚拟物流是军地物流一体化、后勤保障社会化的一种组织模式,其关键点在于实现军地物流资源的全面共享和任务协同运作。而网格技术的核心则是资源共享和虚拟组织中的协同问题求解。因此,采用网格技术实现军事虚拟物流运作是一种理想的途径。作为开展军事虚拟物流的基础性研究工作之一,研究在网格环境下,如何实现军内外不同地域、不同领域、不同优势的物流资源的共享和基于军事物流保障任务的物流资源优化组织,是建立军民融合的军事物流体系,全面建设现代后勤的重要内容,也是有效整合和充分利用军队和社会两方面物流资源,优化物流资源配置,提升军事物流保障水平面临的非常重要的问题。论文采用网格等相关技术和方法,围绕军事虚拟物流资源优化组织问题,对网格环境下的物流资源共享与优化组织展开了深入研究。论文主要研究内容如下：(1)面向军事虚拟物流领域应用,以WSRF规范为基础,利用0GSA作为军事虚拟物流网格系统的基础平台,构建了军事虚拟物流网格体系结构,研究了军事虚拟物流网格资源分布式组织框架及其结构等内容；(2)针对军事虚拟物流资源规范化表达和封装问题,研究了具有支持可扩展性的军事虚拟物流资源的表达模型,给出了军事虚拟物流资源的分类体系和信息表达结构框架,在此基础上,采用元数据和XML/RDF方法,完成了军事虚拟物流资源的规范化表达；并研究了基于WSRF架构的军事虚拟物流软件资源的服务化封装方法；(3)为了提高军事虚拟物流资源组织的可靠性和资源检索效率,同时,满足网格环境下军事虚拟物流资源组织的动态性、可扩展性等要求,构建了基于一种改进的Chord的军事虚拟物流资源组织覆盖网络,研究了该覆盖网络的构建方法、资源子域的动态管理以及基于该网络结构的军事虚拟物流资源的注册与检索方法；(4)针对军事虚拟物流资源需求匹配问题,研究了面向军事虚拟物流任务需求的军事虚拟物流资源匹配模型,给出了一种标准通用的、可扩展的、具有需求资源定义自主性和规范性,并且支持单一功能和综合功能物流资源定义的军事虚拟物流任务需求资源定义模型,以及基于需求资源定义的军事虚拟物流资源匹配算法流程,实现了单一功能类物流资源需求匹配和综合功能类物流资源需求匹配；(5)针对资源优化评价问题,从资源入库评价和资源使用后评价两个角度,设计了军事虚拟物流资源自我评价和用户评价指标参考体系,构建了基于物元模型的军事虚拟物流资源自我可拓综合评价模型和用户可拓模糊综合评价模型,并深入研究了能够满足不同类型资源评价需要、体现用户偏好的评价指标及其权重以及指标综合值统计影响因子动态设定方法,实现了面向用户应用需求的物流资源优劣排序和物流资源用户评价的等级划分；(6)在上述关键技术研究的基础上,研发一个军事虚拟物流网格原型系统,验证了上述研究成果。更多还原

【Abstract】 Military virtual Logistics is a kind of organization mode of the military and civil logistics’ integration and military logistics socialization. Its purpose is to reach military and civil logistics resource share and business cooperation. And that the core of grid technology is just to solve the problem of resource share and business cooperation in virtual organization. Thus, it is a perfect approach to implement the military virtual logistics operation using the grid technology. As one of the basic research of military virtual logistics, studying on the problem that how to make both the inside and outside army’s logistics resources in different region, subject and specialty share and optimization organization to implement military logistics support task is the main content of establishing the military logistics system under military and civil amalgamation and constructing modern logistics across-the-board, and also is the all-important problem confronted with the utilizing the military logistics resource and social logistics resource effectively, optimizing logistics resource deployment, and improving the ability of military logistics support. In the paper, aiming at the optimization organization of military virtual logistics resource, the problem of logistics resource share and optimization organization has been studied in depth by grid and other correlative technology. Main research contents as follows:(1) Facing the region application of military virtual logistics, a military virtual logistics grid architecture is designed according to the criterion of WSRF, using the OGSA as the grid foundation platform. Furthermore, a distributed organization framework of military virtual logistics resources in the grid and its structure are studied.(2) Aim at the problem of standardization description and encapsulation of military virtual logistics resources, an extendable description model for the military virtual logistics resources is presented. Concretely, in the model, a sort system and a description framework of military virtual logistics resources are given out, and then, a method for military virtual logistics resources standardization description by XML/RDF based on the metadata set is given out. Additionally, a service encapsulation method for military virtual logistics software based on the WSRF is brought forward.(3) In order to improve the reliability of military virtual logistics resource organization and the efficiency of resource search, and meet the requirements of dynamics and extendibility of military virtual logistics resource organization in the grid, a virtual overlay network model of military virtual logistics resource organization using an improved chord is constructed, and then the virtual overlay network construction method, the node dynamic management method, and the military virtual logistics resource registration and search method in the network are presented.(4) Aim at the problem of matching for military virtual logistics resource, a model of matching for military virtual logistics resources, facing the requirement of military virtual logistics task, is studied. In the model, a general and extendable resource requirement definition model is given out, which has the characteristics of self-determination and criterion, and supports single service function logistics resource and integrative service function logistics resource definition, and a algorithm flow of matching for military virtual logistics resources based on the resource requirement definition is presented. The model implements the matching for single service function logistics resources and integrative service function logistics resources.(5) Aim at the problem of resource optimization evaluation, a self-evaluation indexes system and a user evaluation indexes system of military virtual logistics resource are designed, and then a extensive comprehensive self-evaluation model and a fuzzy extensive comprehensive user evaluation model of military virtual logistics resource based on matter element model are constructed, from two points of view which are resource evaluations while being saved in database and after being used. Furthermore, in the above models, a dynamic setting method for evaluation indexes, index weight and the influence factor of index value statistic is presented, which can meet the requirement of resources of all sorts evaluation and embody the user’s predilection. The results of above studies implement arranging logistics resources in self-evaluation value sequence and ranking logistics resource according to user evaluation value.(6) Finally,a prototype system of military virtual logistics grid for logistics resource optimization organization is developed, which proves above studies.更多还原
