【摘要】 实施CIMS的关键在于集成，集成首先是信息集成，信息集成提高了企业的现代化管理水平和整体经济效益。科学有效的建模方法是设计集成的信息化系统的关键问题之一。现有的建模方法如CIM-OSA体系结构、GIM方法、IDEF系列等在集成方面存在一定的不足。另外，近几年来敏捷制造、并行工程、企业经营过程重组等技术逐渐成为企业提高生产效率、扩大市场的手段。由于工作流技术能够将应用逻辑和过程逻辑分离，可以不修改具体功能实现而只修改过程模型来改变系统功能，所以在信息系统中得到广泛应用。 本文在IDEF系列方法的基础上提出了一个支持工作流的CIMS建模方法——WFOMM。WFOMM模型集包含四个模型，即动态模型、组织模型、功能模型和信息模型。WFOMM采取了以动态模型为基础，进行必要的添加、分析和提取，生成系统的功能模型和信息模型的方法，达到集成多视图建模的目的。动态模型用来描述企业的实际业务流程，它以IDEF0方法为基础，扩充了单证、业务和角色等信息。功能模型能够直接指导系统的设计，是整个模型集的核心。它是将动态模型中需要计算机处理的，工作流系统需要的功能信息提取出来而生成。信息模型是从功能模型中提取出数据信息，并建立各个数据实体之间的联接关系生成的。组织模型描述了企业组织机构的层次化结构，定义组织中不同的角色。在整个模型集中除组织模型以外，其他模型均实现了处理方法、数据信息和角色的封装。在此过程中，既实现了模型的一致性，也克服了常用建模方法中数据与处理分离的弱点。同时，由于信息模型的建立以功能模型为基础，实现了复杂系统的自然分割，减少了问题空间的复杂度。 除此以外，笔者还开发了一套基于WFOMM的建模工具软件，为模型集的建立提供支持。本文简要介绍了该软件系统的实现方法、开发和运行环境及功能。更多还原

【Abstract】 When the CIMS is driplemented, the key is integraion. A scientific andeffective modeling methodology is the driportan part to design an integraedichrmation system. The existing modeling methods, such as Cm-OSA, GIM andlDEF, has some shortages in the integration. These days, the flexiblemanufacturing tecboque, concurrent engineering tecboque, and business processreengineering technique are gradually used in enterprises to improve productionefficiency and strong competitive caPability. Workflow tecboque can separate theaPplication logic from process logic. lt can transform fimctions of the system bymodifying the process model, and the implement script of these fimctions is notneed to be changed. So WoAnow tecboque is widely used in the informationsystem.In thes thesis, an CIMS multi-view modeling method--Wormow Orieniedmulti~view modeling method (WFOMM) is eXPounded. Four most imPortanviews (dynamic, orghaZaion, fimction and drirmation) were chosen to set modelof system. Based on the dyndric model of system, the function model andichrmation model of system were set tbrough addition, analysis and abstraction.The dynamic model is based on IDEF0 method in order to describe the businessprocess of enterprises. There are information of forms, business and role in thedynamic model. Function model is used to suPport the system design, and it is thefocus of the Whole model collection. The information of dynamic model isabstracted to fOrm funCtion model. ComPther Processes and WoAnow systemneed this information. Information model have the data infOrmation of fimCtionmodel and itS relationshiPs. OrghaZaion model describe the architecture of anenterprise orgwhZation, and it defines all kinds of role. Dynamic model is theencaPsulation of data. Process and role, the same to funtion model andinfOrmation model. These modeling methods not only implement the consistencyof models, bul also save the problem of separaion betWeen data and process.Because infOrmation model is set based on driction model, complicated systemwas divided natUrally and the comPlication of problem was decreased greatly.Fdriermore, author design a based on wrOMM modeling tool software. It isused to make the model collection. The irnplement method, the function andrunning environ!nent of the softwar are described in thes thesis.更多还原
