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
Due Date
A
212
B
209
C
208
D
210
Duration (days)

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.
