( 2 ) system communication pattern is studied , and coarse - grained web services are designed to transmit data for satisfying the requirement of cross - platform . ( 3 ) in accordance with the goals of web services design and modularization demand of system , xml schema is designed for this system model . ( 4 ) the method of digital meter value recognition is extended ( 3 )设计了本系统模型下的xmlschema ,使用符合此架构的xml封装数据,使得系统业务功能的扩展与改变与数据交换无关, xmlschema的应用更好的符合了webservices设计目标和系统模块化要求。
The paper utilizes the standards to describe the nel and bml models for special equipments in power system and fills the blank in this field , then establishes the basis in theory to realize the integrative power system communication network management based on services . hu wei ( electric power communication network ) directed by prof 同时利用标准化建模的方法,构建了电力系统特定设备的网元层和业务层模型,填补了目前此方面工作的不足,为实现以业务为中心的电力系统综合化网络管理系统奠定理论基础。
It is a communication network of different - constitution style . therefore , a set of corresponding telecommunication network management system should be built so that it can transmit all kinds of important business for the power system under the state of stability 、 reliability 、 high - quality and high - speed . my literature regards tmn as the basic system , discusses the scheme of the integration power system communication network management system , brings up the layer network management architecture based on web . this thesis develops the protocol conversion software of the different network elements in power system communication network . the software make a sound foundation for the further research of the network management . at last , the development experience of telecomm management system is used for reference , prospects the development of telecommunication network management system 要保证这个庞大的通信网络稳定、可靠、优质、高速传输电力系统中各种重要通信业务,必须建立一套与之相适应的网管系统,最终实现运行、维护、经营、管理的科学化和现代化。本文以电信管理网( tmn )作为基础体系,探讨了电力通信综合网管系统的设计方案,提出了与电力通信网相适应的基于web的层次化网管系统体系结构。同时开发了电力通信网中各网元的标准协议转换接口模块,利用它实现对电力通信网不同监控设备的有效管理,为网络管理的进一步研究打下基础。
From the simulative experiment and comparing of different cooperative model , we find that toac cooperative model can solve multi - agent social organization , social convention , social evolution , coalition strategies , coalition stability , collaborative problem solving and task allocation in open and distributed multi - agent systems ; can organize multi - agent cooperation , enhance system dependability , reduce resource cost and system communication bottleneck problem ; can share the task and result of multi - agent , and can reach the global optimal of multi - agent utility in task oriented domains ; from time performance , toac model is better than cnp ( contract net protocol ) of r . smith , blackboard cooperative model of newell and the result share model of smith and davis 通过仿真试验和结果分析,发现本文提出的toac模型,该模型能够有效的解决在开放、分布的mas环境中,多agent的社会组织、社会规范、社会演化、联盟策略、联盟稳定性、合作问题求解和任务分配,能够有效的组织多agent间的协同、提高系统的可靠程度、降低资源开销和系统通信瓶劲问题,能够实现多agent任务和结果共享,并能够达到面向任务领域多agent联盟效用的全局最优。时间性能上toac模型要优于r . smith的合同网协同模型、 newell的黑板协同模型,以及smith和davis的结果共享协同模型。
