【摘要】 本文是以国家自然基金资助项目“我国农林航天育种科技产业的技术准备及管理体系的研究”为研究背景，针对当前航天育种领域所存在的管理上的问题，提出基于工作流技术的航天育种管理体系建设的构想，并介绍了其中搭载申请评估子系统的具体设计和实现细节。同时，对工作流管理技术以及实现航天育种管理信息系统所采用的技术作了详细的介绍。本文共四章： 第一章：工作流基础知识介绍。介绍了工作流管理产生的历史必然性、工作流和工作流管理系统的基本概念和定义、工作流参考模型和工作流技术的特点和研究发展情况，并分析了将工作流技术应用于航天育种管理系统的优点。通过本章的介绍，我们将得到对工作流管理的较为全面的认识。 第二章：航天育种管理体系的分析与设计。本章分析了当前航天育种领域存在的管理上的问题，提出了航天育种管理体系的目标层次和面向过程的管理方案。 第三章：基于Web的工作流实现技术基础。本章首先介绍了三层应用软件体系结构，接着对目前流行的三种三层Web体系结构进行了分析和比较，最后，文中介绍了微软的构件对象模型COM／DCOM的技术原理和开发步骤。 第四章：航天育种管理系统的设计与实现。本章首先介绍航天育种管理系统的特点，提出了航天育种管理信息系统的总体设计，并重点介绍基于工作流管理的项目评审子系统的实现以及搭载申请的量化评审体系的模型和算法。更多还原

【Abstract】 This paper is based on "Study for China’s Space Breeding ManagementSystem and Decision Support System", the project which was supported by theNationa1 Natural Science Foundation of China. After ana1yzing the prob1ems ofmanagement in the fieId of space breeding, we propose a solution of constrUctingthe Space Breeding Management System, which is based on the technology ofworkfiow management. ln this papeF, the concept and architecture of workflowmanagement is introduced, the technology used in the implementing of SpaceBreeding Management System is described. Finally, a particular description ofthe evaluating system is given.The thesis contains four chaPters as follows:Chapter I: Basic knowledge of Workflow The development of theworkflow management, the concept and definition of the workflow and WfMSare introduced. The characteristics and the development of the workflow and theWorkflow Reference Model are described. Through the introduction of thischaPter, we can have a whole idea about Workflow Management.Chapter II: The analysis and design of the Space Breeding ManagementSystem. The problems about management of the space breeding are analyzed inthis chaPter, and the goal hiberarchy of the Space Breeding Management Systemand a process-oriented management solution is proposed.ChaPter III: The reIevant technology of WCb-based worndow management.ln this chaPtef, the three-tiered software architecture is intrOduced firstly, thenthe basic principles and features of three kinds of popular 3-tier web architectureare discussed and analyzed. Finally, this chapter analyzed the distributedcomputing Architecture based on COrmCOM in detail, and summarized someimplementing methods of COimCOM.ChaPter lV: The design and implementing of the Space BreedingManagement System. ln this chaPter, the features of Space BreedingManagement System are discussed. And the preliminary design is proposed. Theimplementing of the workflow-based evaluating system is introduced in detail.This chaPter aIso described the modeI and arithmetic of the eva1uatingarchitecture.更多还原
