함정의 최적 운용가용도 산출을 위한 개선안 연구

Abstract

With the increasing interest in ILS, the military and private sectors have recognized the importance of this. A number of studies on RAM target value management are in progress, however, the researches for the warships and vessels are relatively hard to find out. Unlike other weapon system or equipment, the warships and vessels operate for long period and the operational status could be divided into offshore and shore, which is different from other systems. For the warships and vessels the preventive maintenance time is significantly long, so counting this time into non-operating time makes an error to get the precise operating time of the warships. To find the more precise RAM target value, the new concept of operating time of the warships including preventive maintenance time is proposed in this paper and the calculation result for the example case shows the improvement of the operating ratio. In the result the operating availability is shown approximately 11% of difference. To confirm the usability of this proposed method, AHP(Analytic Hierarchy Process) method is used. Through the interview of 10 navy soldiers and shipbuilders experts, the obtained value of weighting influence is 1.35 to 3.41. This means the proposed concept is more realistic than exiting method.
