Abstract
This paper presents a method of economical evaluation of maintenance strategy and its life cycle cost at the design stage. The purpose of this method is to determine the optimum design and specification of the building under consideration. Although the method used now to determine the maintenance strategy generally depends on the experience and intuition, there are several problems. Those are as follows : 1. The building maintenance strategy depends on the purpose of the usage, management level of owners, and requirement level of occupants. 2. There is not enough discussion about the methodology to determine logically maintenance cycle, timing and the amount of maintenance. 3. As we do not have the life-cycle-cost evaluation systems of the life of a building, we can not select the optimum solution among the alternatives. This paper discribes planning model of maintenance and some computer simulation models. Then using these models, the nature of the periodic maintenance, corrective maintenance and replacement is disccussed. Conclusions are drawn as to the relevance of the application of the model to the parts of a building.
