The Research on Collaborative Engineering due to Jointed Process Information

本研究是基于设计过程信息的协同工程方法论。本文的研究结果可以归纳为以下四点：1、研究结果的有效性；设计流程研究人员对船舶设计流程进行了分析。特别从并行工程的角度研究了船体设计与配管设计的协同阶段。设计过程建模提出了一个设计过程信息清晰化的框架。在此框架下，提出了两个概念作为设计模型的基本要素。一个概念是“实体信息”，另一个概念是“属性信息”。设计过程模型是设计工作流的基础。协同设计过程的网络化设计信息处理的特点是从粗设计到细设计的过程，因此提出了“模型结构规范”和“模型状态规范”两种设计流程。模型结构规范是指用实体和属性信息模型描述的产品模型结构。模型状态规范是对已定义模型中关系和属性值信息的明确描述和管理。设计过程的网络表示设计工作流。利用这一过程网络进行网络通信，实现协同工作。协同工程原型系统的实现在原型系统中，将驱动模型结构规范和模型状态规范的联合信息处理功能定义为系统组件，设计者利用组件组合进行设计活动。因此，该过程在组件网络中进行描述，并得到了良好的管理。

This research is for the methodology of collaborative engineering due to jointed design process information. The results of this research are summarized the following four points ;1. Workflow of design processThe researchers analyzed the workflow of the process of the ship design. In particular, the collaborative stage of the hull design and piping design are investigated from the viewpoint of concurrent engineering.2. Modeling of design processA framework is proposed that design process information is explicitly. So two concepts are proposed as an elementary factor of design model in this framework. One concept is "Information of entity" and the other is "Information of attribute". The design process model is an elementary of the design workflow.3. Network of design process for collaborativeThe design information processing is characterized as a progress from a rough design to detail design, so two design flows are proposed : one is "specification for model structure" and the other is "specification for model status". The specification for model structure means a structure of product model described by information models of entity and attribute. And a specification for model status means definitely description of information of relation and attribute values in the defined model and management that information. The network of the design process represents the design workflow. Thus collaborative works are attained by the network communication using of this process network.4. Implementation of prototype system for collaborative engineeringIn the prototype system, the jointed information processing functions driving the specification for model structure and the specification for model status are defined as system component, and a designer proceeds design activities using the components combining. As a result the process are described in components network and well managed.
