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:

QUESTION 2
A. In Akhwan Company, operations director Mr Tamad recently realized there had been an
increase in products failing during the final quality checks. These checks were carried out
in the QC (quality control) laboratory, which tested finished goods products before being
released for sale. The product failure rate had risen from 1% to 4% in two years' time which
meant an increase of hundreds of items of output a month which were not sold to Akhwan's
customers. The failed products had no value to the company once they had failed QC as the
rework costs were not economic. Because the increase was gradual, it took a while for Mr
Tamad to realize that the failure rate had risen.
A thorough review of the main production operation revealed nothing that might explain the
increased failure and so attention was focused on the QC laboratory. For some years, the
QC laboratory at Ikhwan, managed by Ramly, had been marginalized in the company, with
its two staff working in a remote…
Question (2):
(15 Marks)
A cylindrical specimen of a nickel alloy having an original diameter of 10.3 mm and an
elastic modulus of 207 GPa experiences only elastic deformation when a tensile load of 8850
N is applied. Compute the maximum allowable elongation if the maximum length of the
specimen before deformation is 475 mm.

The recommended dosage for the flu shot is 0.5mL. The local health authorities define all syringes that have less than 0.45ml or more than 0.55mL as defective. In a sample of 100 syringes, the hospital’s quality control officer finds the average dosage to be 0.5mL. The standard deviation of the dosage is 0.02 mL and the distribution of the dosages resembles a normal distribution reasonably closely. What percentage of the manually filled syringes will be outside the specification limits provided by the local health authorities? (Please answer in decimal form.)arrow_forward
