Question Help 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: Job Due Date Duration (days) 6 3 A B D 212 209 208 210 3 8 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. 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): Sequence Job 1 2 3 4 The average tardiness (job lateness) for the sequence developed using the FCFS rule - days (round your response to two decimal places). The average completion time for the sequence developed using the FCFS rule = days (round your response to two decimal places). The percentage utilization for the sequence developed using the FCFS rule = % (enter your response as a percentage rounded to two decimal places). 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 2 3 4 The average tardiness (job lateness) for the sequence developed using the SPT rule = days (round your response to two decimal places). days The average completion time for the sequence developed using the SPT rule = (round your response to two decimal places). % (enter The percentage utilization for the sequence developed using the SPT rule = your response as a percentage rounded to two decimal places)
