Chapter 13, Problem 35P
A public utility intends to buy a turbine as part of an expansion plan and must now decide on the number of spare parts to order. One part, no. X135, can be purchased for $ 100 each. Carrying and disposal costs are estimated to be 145 percent of the purchase price over the life of the turbine. A stockout would cost roughly $88,000 due to downtime, ordering, and "special purchase" factors. Historical records based on the performance of similar equipment operating under similar conditions suggest that demand for spare parts will tend to approxin1ate a Poisson distribution with a mean of 3.2 parts for the useful life of the turbine.
a. What is the optimal number of spares to order?
b. Carrying no spare parts would be the best strategy for what range of shortage cost?

The average completion time (flow time) for the sequence developed using the FCFS rule = 11.75 days (round your
response to two decimal places).
The percentage utilization for the sequence developed using the FCFS rule = 42.55 % (enter your response as a
percentage rounded to two decimal places).
b) Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the
order in which the jobs were received):
An Alabama lumberyard has four jobs on order, as shown in the following table. Today is day 205 on the yard's
schedule. In what sequence would the jobs be ranked according to the decision rules on the left:
Job

The average tardiness (job lateness) for the sequence developed using the SPT rule = 5.00 days (round your
response to two decimal places).
The average completion time (flow time) for the sequence developed using the SPT rule = 10.25 days…
With the aid of examples, fully discuss any five (5) political tactics used in organisations.
