支持协同设计的船舶设计过程模型研究

船舶设计过程模型是在网络环境下开展船舶并行和协同设计系统的基础.本文根据船舶设计的特点,提出了将船舶设计过程按照项目、设计任务和设计活动三个层次进行分解的方法,并给出了船舶设计过程模型形式化定义.该模型明确了设计任务间的并行、顺序和协同关系,可以直接按设计任务构成活动网络图进行规划、分析、管理等工作,使设计过程具有良好的可变更性和可控性.

Study on the Ship Design Process Model for Cooperative Design

The ship design process model is basic for developing the concurrent a nd cooperative ship design system. According to the characteristics of the ship design, a discomposed method for the ship design process from three layers: proj ect, design task and design activity is put forward and a formal Ship Design Pr ocess Model(SDPM) is given out. The relations of concurrent, dependence and co operation among design tasks can be determined in SDPM. Therefore, the plan, ana lysis and management are performed using the Activity Network Diagram only compo sed of design tasks. This simplifies the Activity Network Diagram and makes the optimization and adjustment of the ship design plan convenient. The adjustment t o the design activity has no affection to other design tasks and the ship design process is easier to control and change.
