Part D: Average tardiness for the sequence developed using LPT rule? The percentage utilization? Thank you!!
The following jobs are waiting to be processed at the same machine center. Jobs
are logged as they arrive:
Job
Due Date
Duration (days)
314

The average tardiness (job lateness) for the sequence developed using the SPT
rule = 4.20 days (round your response to two decimal places).

d) Using the LPT (longest processing time) decision rule for sequencing the
jobs, the order is (to resolve a tie, use the order in which the jobs were
received):
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.
