3 An Alabama lumberyard has four jobs on order, as shown in the following table. Today is day 205 on the yard's schedule. In what sequence would the jobs be ranked according to the decision rules on the left: 4 D Job Duration (days) The average tardiness (job lateness) for the sequence developed using the FCFS rule = 9.75 days (round your response to two decimal places). 8 A B Due Date 210 209 212 5 6 The average completion time (flow time) for the sequence developed using the FCFS rule = 15.5 days (round your response to two decimal places). D 208 3 The percentage utilization for the sequence developed using the FCFS rule = 35.48 % (enter your response as a percentage rounded to two decimal places). All dates are specified as manufacturing planning calendar days. Assume that all jobs arrive on day 205. Compute all times based on initiating work on day 205. b) Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received): Sequence Job 1 D 2 B 3 4 A The average tardiness (job lateness) for the sequence developed using the SPT rule = 7.5 days (round your response to two decimal places)
