| Abstract |
The maintenance of school building is pivotal issue. However, it is difficult to obtain basic analysis data for LCC(Lifecycle Cost) analysis
and maintenance planning of school building. Therefore, this study proposed System Dynamics(SD) techniques to make maintenance decisions
for school building. The interaction between the major parameters related to the aging of a building, maintenance activities, and cost were
expressed in Causal Loop Diagram. Based on this, the formula for the relationship between causal maps was defined and converted to Stock
and Flow Diagram. Through the completed SD model the 50-year plan of 214 educational building were tested by considered in account
budget, maintainability, and budget allocation opinions. As a result, the integrated SD model demonstrated that it can support strategic
decision making by identifying the status class and LCC behavior of school buildings by scenario. According to the scenario analysis, the
rehabilitation action of preventive maintenance that primarily repairs the buildings in condition grade C showed the best performance
improvement effect relative to the cost. Therefore, if the proposed SD model is expanded to consider the effects of other educational policies,
the crucial performance improvement budget can be estimated in the long-term perspective. |
