The Research on Integrated Computer Aided Engineering system for Shipbuilding

为了更安全地进行制造作业，有必要在制造计划阶段获取安全信息。近年来随着信息技术的发展和普及，在企业内部建立了各种工业事故实例数据库，并利用计算机网络开发了便于浏览和共享工业事故实例数据的环境。然而，考虑到与装配作业有关的工业事故案例，很难获得适当的安全信息。本研究透过评估事故风险与安全成本，提出安全管理资讯系统的架构。在该系统中，引入了工业事故案例数据库，并与虚拟装配仿真相结合。安全管理规划人员可以利用虚拟装配仿真来制作装配作业场景，并从仿真中获取危害。然后，系统使用数据库检查每个事故案例，并显示具有风险和成本值的事故替代措施。他/她可以交互选择适当的措施，系统可以显示工作说明，使装配操作更安全。

In order to carry out manufacturing operations more safely, it is necessary to acquire the safety information at the manufacturing planning stage. With the development and spread of IT in recent years, the database of various industrial accident examples is built in a company and the environment which can easily browse and share industrial accident example data is developed using computer networks. However, it is very difficult to acquire the appropriate safety information considering the industrial accident cases relevant to the assembly operations.This research proposes a framework of information system for safety management, by assessing the risk of accident and the cost of safety. In this system, a database of industrial accident cases is introduced and integrated with the virtual assembly simulation. A planner of safety management can make the scenario of assembly operations using the virtual assembly simulation, and get hazards from simulations. Then, the system checks each case of accident using the database and show alternative measures for accidents with the value of risks and costs. He/She can interactively select appropriate measures and the system can show a statement of work to make the assembly operations safer.
