【 摘 要 】

Military facilities play an important role in providing rest and training places for soldiers, protecting ammunition and equipment for wars. Also, the asset value of military facilities is about 30 trillion won. Maintenance of military facilities is very important in order to maintain constant battle readiness and to preserve asset value. There have been studies on the maintenance of military facilities in the past, but the consideration of scheduled maintenance was insufficient and it was complicated to use in the military. Scheduled maintenance is a kind of military facility maintenance that can prevent deterioration efficiently at low cost at the beginning of deterioration. It has the characteristic that the facility user can decide the target, amount, and timing when making a decision for maintenance. However, without considering the indirect environmental effects of the facilities, the budget is distributed based on age and types of facilities. Therefore, facilities placed in a poor environment, for example, frequently used, or located in the coast or the river, lack maintenance cost because much deterioration occurs. This leads to degradation of facility function and shortening of service life. Therefore, in this study, Factor Method was used to develop the service life expectancy calculation model considering the environmental factors of the facilities. As a result of the survey of the military facility experts, ventilation, insulation, location, maintenance team and frequency were found to have a great influence on the life span of the facility. As a result of applying the developed model to the similar age and type facilities, the estimated service life of the facilities in the severe environment was calculated to be shorter. The proposed methodology can calculate the service life considering various indirect environmental factors affecting the military facilities. The proposed methodology will provide a basis for distributing more maintenance costs to facilities with shorter service life expectancy among facilities of similar facility type and age. The results of this study will enable effective preventive maintenance of military facilities and contribute to maintain their function and extend the service life of military facilities.
