The following jobs are waiting to be processed in Rick Carlson's machine center. Carlson's machine center has a relatively long lead time and sets new schedules every 2 weeks, which does not alter previous schedules. Below are the jobs received during the previous 2 weeks. They are ready to be scheduled today, which is the start of day 241. At this time, there are no other jobs in progress or waiting to be worked. Jobs are due at the end of the day shown.

Job	Date of work received	production days needed	Job Due Date
A	225	25	270
B	228	15	300
C	230	35	325
D	231	30	310
mi	235	40	360

For the following 2 sequence rules, calculate the average flow time since today (consider that today, which is the start of day 241, is day 1 to determine the flow time), the average days late (no credit for being early), and the average number of days early (zero days in advance for a job that is late). The remaining workshop time is equal to the production days needed. The rules are as follows: 

• Slack 

• CR (Critical Ratio)
