Facility Layout Problem Considering Safety Space for Hazardous Materials Defined by Fire Service Act

Abstract

Determining an efficient layout is very important to increase the productivity of a factory with multiple departments. There are many papers about facility layout problems, but there are few papers about facility layout problems involving hazardous materials defined in the Fire Service Act. Among them, there is no literature considering the safety space required for hazardous materials as defined in the Fire Service Act. Therefore, in this research, we propose a facility layout problem that considers providing a safety space for hazardous materials as defined in the Fire Service Act. In addition, hazardous materials storage facilities are classified into two types, indoor storage facilities and outdoor storage facilities, and the width of the safety space changes based on the type of storage facility selected. In this research, we realize the optimal solution to the facility layout problem by incorporating the change in safety space required based on the storage facility type selected. We conduct multiple experiments utilizing virtual data compiled by the authors and actual data obtained from collaborating company.
