You are asked to schedule and evaluate two sequencing rules. You are ready to schedule these six jobs. They are all ready to be processed. Show all work and calculations

a) Determine the sequence of jobs using the following rules:

• Slack using the definition of the slack ratio rule that we used on our assignment
• Based on the day the job was brought to the shop

b) Prioritize the rules used in a) based on average flow time measured from now.

c) Prioritize the rules used in a) based on average lateness with no credit for completing any test early (in other words, the late time would be set at zero if a job is early).

d) Prioritize the rules used in a) based on average early time with no penalty for completing any test late (in other words, the early time would be set at zero if a job is late).
