On the Simultanously Determining the Schedule and Crew Size for Optimal Preventive Maintence

수리일정계획(修理日程計劃)과 보수반원(補修班圓)크기의 동시적(同時的) 결정(決定)에 관한 연구(硏究)

Past treatment of the single machine maintenance problem has shown that preventive maintenance may be desirable for equipment for which failures are caused at least partially by wear-out factors. In all previous treatment, however, the size of the maintenance-repair crew has been held constant and the optimal maintenance period has then been determined. This paper suggests a simultaneous solution for the maintenance-repair crew size and the optimal maintenance period. The optimal maintenance period is seen to shift as the size of the maintenance-repair crew varies.
