Question 4: For a compressor the probability of failure occurring during a given week is given in Table Q4. (1) Calculate the Annual Breakdown Maintenance Costs (where no Preventive Maintenance is carried out), The costs are 300 OMR to repair the compressor, every time it fails. (H) Preventive maintenance costs 60 OMR for each service. Calculate if Preventive Maintenance is cheaper than Breakdown Maintenance, and if so how often Preventive Maintenance should be carried out. There are 48 working weeks in a year. Table Q4 Probability of failure during the given week Week of Operation 1 0.07 0.40 0.53
