The layout problem involves finding the best arrangement of physical components of the service system possible within the time, cost, and technology constraints of the situation. And the layout problem can be a very complex system design problem requiring the most sophisticated lay system analysis and design tools in order to develope satisfactory layout solutions. The objective of this layout study is to reorganize service rooms for minimizing overall patient's moving distance. In solving the service room layout problem, there exist a number of constraints on the building facilities in current location. All other service rooms can be moved if layout analysis indicates it would be beneficial. The first step is to analyze records in order to determine the number of trips made by patients between departments in two months. And a number of layout cases developed as methods to a good service room layout. The result is shortened total patient's layout distance of 252,880 meters.
