About this document
Optimum Preventive Maintenance Frequencies by Farooq Israr is a document available to read on EtoBox.
The document provides information on the average time between breakdowns, standard deviation, preventive maintenance cost, and breakdown cost for equipment A201, B400, and C850. It outlines calculating the ratio of preventive maintenance cost to total cost and using z-tables to find the number of standard deviations from the mean. This allows determining the optimum preventive maintenance frequency for each piece of equipment as the mean time between breakdowns plus or minus the number of standard deviation
