Looking for help solving the last part. Thank you!
a) Using the FCFS (first come, first served ) decision rule for sequencing the jobs,
the order is (assume that jobs came in the order in which they are listed in the
table):
The following jobs are waiting to be processed at the same machine center. Jobs
are logged as they arrive:
Job
Due Date
Duration (days)
Sequence
Job
A
314
315
3
313
2
B
312
16
3
C
325
40
All dates are specified as manufacturing planning calendar days. Assume that all
jobs arrive on day 275. Assume each job starts at the beginning of the day and
finishes at the end of the day (a job that begins on day 275 and takes 8 days will
finish on day 282, and the next job begins in the morning of day 283). Compute all
times based on initiating work on day 275.
4.
The average tardiness (job lateness) for the sequence developed using the FCFS
rule = 4.20 days (round your response to two decimal places).
The percentage utilization for the sequence developed using the FCFS rule =
% (enter your response as a percentage rounded to two decimal places).
