System Design Laboratory

The arrangement design of a ship’s engine room must consider various factors, including interference from equipment and pipe located in the engine room, design rules, previous ship data, and expert knowledge. The arrangement design process for ships with many complex and customary areas relies on previous ship data and experts’ design experience or know-how. During the pipe routing design process, pipe routing relies on experts’ design experience and know-how. In order to complement the pipe routing of ships that rely on experts, this study propose a pipe routing optimization method by constructing an expert system that can systematize expert knowledge and combine it with optimization techniques. An Arrangement Template Model is constructed to represent the data structure, and an Arrangement Evaluation Model is used to evaluate the expert knowledge of real experts and computerize it systematically. The optimal arrangement results evaluated by the Arrangement Evaluation Model are used as the objective function of the optimization problem. For deriving an optimized design proposal by reviewing multiple designs in a short time, the optimization technique is combined with the expert system, and the optimization problem is formulated using it.
