A new job has just arrived at a production facility. It is currently the start of day 143, and we assume 8 hours of productive capacity available per day. The job calls for the production of 200 units. The following lists the operations required and the appropriate time standards:

a. If the operation uses forward scheduling and launches the job into production immediately, when should we expect it to be done, assuming the right capacity is available when called for?

b. The customer has requested a delivery date of day 170.

If we use backward scheduling from that day, when is the latest the job should be started, again assuming the right capacity is available when called for?
