A Simulation Model for Machine Efficiency Improvement Using Reliability Centered Maintenance: Case Study of Semiconductor Factory

Table 8

Cost structure for performance measures.

Cost structure
Total cost (TC)	TC = CGP − CLD − CPM
Cost of preventive maintenance (CPM)	CPM = (CC) + (TeC)
Component cost (CC)	CC = (Total_Component_Replaced) * (Cost/Component_Unit)
Technician cost (TeC)	TeC = (Total_Time_Repaired) * (Cost/Hour)
Cost of good product (CGP)	CGP = (Total_Good_Units) * (Cost/Good_Unit)
Cost of lost product (CLD)	CLD = (Total_Lost_Units) * (Cost/Lost_Unit)
