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:

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 $275.$
