Some Key Issues In The Enterprise Cooperative Design

With the advance of computer performance and the development of network technology, computer system has change the mode of solve the traditional problem and math computing to support the broad and effective working mode -Cooperative, that means to help a group of people to interactive and support their cooperative work. As a new research area, since it is putted forward at middle 80th, computer supported cooperative work (CSCW) has been recognized by most of people, now it is one of the most rapid development research areas.The Research work of this paper is oriented to the enterprise cooperative design. All of these works are based on the HuBei Province key research project "Intelligent engineering graphics library management system based on cooperative work" (No. 9602p0117) and National fund project (69375018).The primary work of this paper is following:1. Synthetically analyses the current state of enterprise design, give a CSCW model of enterprise. And analysis the process of cooperative design in enterprise. Put forward a multi-tier model of enterprise cooperative design.2. Synthetically analyses the workflow management systems in the overseas and domestic. To meet the requirement of enterprise cooperative design, put forward the requirement of workflow management system that can integrate enterprise. That is: it can support dynamically federation, based on procession and have the agile ability.3. To the problem that current workflow management can't adapt to heterogeneous, distributed computing environment, can't watch the application that not started by workflow management system, in our workflow management system, we use CORBA technology to solve the above two problems. And borrow the method that DBMS solve concurrent control, we give a new solutions to the concurrent control of workflow management.4. Synthetically analysis the CSCW system architecture in the overseas and domestic. In the process to improve on traditional CSCW system architecture-Client/Server. Put forward and realize a "self-adaptive distributed architecture", it not only give a new manner to traditional enterprise cooperative design, but also solve the legacy system database-access problem. And in the cooperative design system, we introduce the architecture based on Agent and the idea of flexible software system.5. Directed by above theory, we carry out three systems:· A workflow management system based on CORBA-CoDICGRS_Flow;· A computer video conference system based on H.323V2 standard-CADCS_Meeting;· A mid-scale and mid-complexity mechanical design system---CoDICGRS. The above work involves 50, 000 lines program.
