摘要
本论文首次将CIMS(Contemporary Integrated Manufacturing Systems,简称CIMS)的理念和方法论引入到水利枢纽体系结构分析以及实现系统调度集成。在基于CIMS功能建模(IDEF0)、信息运行模式分析和建立水利枢纽合理、科学的体系结构的基础上,提出以过程集成(IDEF3)方法建立水利枢纽防洪调度和水资源调度业务流程模型。为实现整体集成,本文提出了以工作流管理技术(Workflow Management Technology)实现水利枢纽信息、功能以及过程集成,从而实现集成化的调度管理;并给出了基于分布式工作流服务/工作流机的整体集成实现的软件框架。主要内容有三个方面:
     1.水利枢纽体系结构分析;根据对研究对象CIMS体系结构现状的分析,以及CIMS模型理论(体系结构理论、IDEF0等)与系统集成的总体目标,分析了现有系统的体系结构。在此基础上,提出了水利枢纽CIMS的合理体系结构,即给出了合理的功能结构、逻辑结构、递阶控制结构、决策-调度-现场控制应用系统结构。
     2.水利枢纽过程建模与知识获取;提出了以实现防洪调度和水资源调度的过程(业务流程)集成。以过程建模理论(IDEF3)为基础,与IDEF0、信息运行模式相互参考,针对调度管理业务流程进行过程建模分析。过程建模分析结果证明,可以通过角色、组织、资源与应用程序(系统)的过程集成来实现集成化的调度管理系统。IDEF3过程建模可以作为工作流模型的知识获取工具。
     3.提出系统整体集成框架。本文提出了将IDEF3模型转化为基于活动网络图的工作流模型;为实现过程集成,本文参考并给出了基于分布式工作流服务/工作流机的整体集成实现的软件框架。此系统集成框架可以有效地满足对象对调度管理系统的安全性、分布式、交互式、柔性等要求。
The conception and methodology of CIMS (Contemporary Integrated Manufacturing Systems) are introduced first by this paper in analyzing the CIMS architecture of the hydro-junction and in integrating the whole system. Based on analysis with the CIMS methodology of function modeling and information modeling on the existing system and setting up a rationalized and scientific architecture of the hydro-junction, the automatism realization on the operation flows of the flood control scheduling system and the water resource distributing system is modeled with the CIMS' process integration methodology (IDEF3). For accomplishing the whole computer integration of the system, the Workflow Management Technology (or system) is introduced by this paper to solve highly integrated computer system, including function, info and procedure integration, therefore to accomplice the integrated scheduling management system; and the software frame of the computer whole integrated system is put forward, based on the technology of the distributing workflow service/workflow processor. There are three points on this paper:
    1.The analysis on the architecture of the hydro-junction; According to study the existing CIM architecture of the object, and the CIMS' modeling theory (including the CIM architecture theory, IDEFO, etc) and the macro aim at the computer integration, the advantages of the existing model of computer integration are pointed out, and its CIM architecture is analyzed. Based on the fundamental study, a kind of rational CIMS architecture of the hydro-junction is given out, including its rational function structure, logical structure, and hierarchical control, decision-scheduling-field's control application system structure.
    2.The knowledge acquirements on the process modeling of the hydro-junction; Based on the actual conditions of the fundamental operation flows and application sub-systems, the process (operation flow) integration is put forward, carrying out the scheduling automation in flood control and water resources distributing. Based on the CIMS process modeling, and referring the IDEFO models each other, the operation flows only of the scheduling managements are modeled and analyzed. The results of the process modeling prove that the available process integration is able to bring out the highly integrated computer system to carry out the scheduling managements of the synthetic operations.
    3.The whole integrate computer frame. Through studying the developing stage of the system integration, process integration is the higher developing stage of function and info integrations. Workflow management system can integrate the three. Therefore, the IDEF3 models can be transformed to the workflow models based on the theory of the active net diagram. For accomplishing the whole computer integration of the system, the Workflow Management Technology (or system) is introduced by this paper to solve highly integrated computer system, including function, info and procedure integration. The software frame of the computer whole integrated system is put forward, based on the technology of the distributing workflow service/workflow processor. The system integrating frame can satisfy the requirements by the scheduling management system on security, distribution, flexibility, and interactive.
