Framework for Modeling Dependencies in Collaborative Engineering Processes

This article describes an engineering process representation and modeling tool. The approach is especially suitable for describing large-scale, mature design processes involving numerous tasks, some of which may be performed by automated computer agents. The underlying representation is a graph of information-processing units with explicitly defined input and output feature elements. We show that this representation is more complete than those used in previous process modeling approaches and overcomes some of their limitations when dealing with design processes involving dependencies at multiple levels of detail. The representation is combined with rules for automatically operating upon the graph to preserve consistency when traversing to higher or lower levels of detail.

制造业企业信息集成的平台PDM

以往的CAx、ERP、CRM等的应用,没有从企业全局信息的角度出发,造成了企业信息系统数据流庞大、信息冗余、数据和过程缺乏透明性等问题。目前,一个比较好的解决方法就是以PDM为平台集成这些孤立的应用系统。简要介绍了PDM的发展状况和功能,以及它与CAx和ERP的集成。     

Internet-Based Collaboration System: Press-Die Design Process for Automobile Manufacturer

To survive in a severe competitive environment, manufacturing enterprises must accomplish objectives such as cost reduction, quality improvement and short time-to-market. Also, as the manufacturing environment becomes more globalised and distributed, it is important to manage the workflow harmoniously and to share the information efficiently among geographically dispersed users. In this research, we propose a collaborative design and engineering system, which manages various design processes in an integrated manner and enables the sharing of design information. Because design information is usually very large in its size, it is very difficult to synchronise the individual design data of each designer with the entire design data. As a solution for efficient data sharing among the designers in networks, CORBA can be applied to synchronise the states of the design information. If one user modifies design data on his/her computer, this operation is detected and transmitted to other users who are related with the design modification. A receiver’s computer automatically synchronises its data with the sender’s message. In this paper, an Internet-based collaboration system for a press-die design process for automobile manufacturers is developed with CORBA, Java, Java3D and a relational database system. After modelling a practical press-die design process with the UML language, workflow routing paths are created by the modelling data. Cost and time for design can be estimated by the concurrent quasi-procedural method. The system developed can notify design modification to users when it is required, and enables users to share design models and analysis results. Designers can exchange opinions about common design matters by the conferencing function of the system. ID="A1" Correspondence and offprint requests to: S. H.
