Question
Chapter 17, Problem 1DQ
Summary Introduction
To determine: The objective of maintenance and reliability.
Introduction: Reliability is the probability that a product can perform over a specific period. It is the consistency of the product to perform in the same way for a particular period of time.
Expert Solution & Answer
Explanation of Solution
The objective of maintenance and reliability is as follows:
The major objective of maintenance and reliability is maintaining the ability or competency of certain system in the meantime while controlling the cost of the system.

Hint:
Step 1:Compute the ratio of preventive cost to breakdown cost for each piece of equipment (round to a maximum of four decimals).
Step 2:
Find the z value corresponding to the ratio from Step 1 and use this value of z to compute…

QUESTION 6 (MAINTENANCE AND RELIABILITY: COMPARING PREVENTIVE AND BREAKDOWN
MAINTENANCE COSTS)
17.24 Wharton Manufacturing Company operates its 23 large and expensive grinding and lathe machines
from 7 A.M. to 11 P.M., 7 days a week. For the past year, the firm has been under contract with Simkin and
Sons for daily preventive maintenance (lubrication, cleaning, inspection, and so on). Simkin's crew works
between 11 P.M. and 2 A.M. so as not to interfere with the daily manufacturing crew. Simkin charges $645
per week for this service. Since signing the maintenance contract, Wharton Manufacturing has noted an
average of only three breakdowns per week. When a grinding or lathe machine does break down during a
working shift, it costs Wharton about $250 in lost production and repair costs.
After reviewing past breakdown records (for the period before signing a preventive maintenance contract
with Simkin and Sons), Wharton's production manager was able to summarize the following patterns:
