Contract for Preventive Maintenance ,[object Object],[object Object],[object Object],[object Object],OPM 533 11-

Maintenance Cost Example Should the firm contract for maintenance on their printers? Average cost of breakdown = $300 Use service contract - cost RM150 per month and average breakdown is 1 per month. Number of Breakdowns Number of Months That Breakdowns Occurred 0 2 1 8 2 6 3 4 Total: 20

Maintenance Cost Example ,[object Object],= (0)(.1) + (1)(.4) + (2)(.3) + (3)(.2) = 1.6 breakdowns per month Number of Breakdowns Frequency Number of Breakdowns Frequency 0 2/20 = .1 2 6/20 = .3 1 8/20 = .4 3 4/20 = .2 ∑ Number of breakdowns Expected number of breakdowns Corresponding frequency = x

Maintenance Cost Example ,[object Object],= (1.6)($300) = $480 per month Expected breakdown cost Expected number of breakdowns Cost per breakdown = x

Maintenance Cost Example ,[object Object],= (1 breakdown/month)($300) + $150/month = $450 per month Hire the service firm; it is less expensive Preventive maintenance cost Cost of expected breakdowns if service contract signed Cost of service contract = +
