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):

Looking to have entirety of this question answered.

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 . B C D Due Date 212 209 208 210 Duration (days) 6 3 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. 3. 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 A 2 B 3 4 D days (round your response to two decimal The average tardiness (job lateness) for the sequence developed using the FCFS rule = places). The average completion time (flow time) for the sequence developed using the FCFS rule = places). days (round your response to two decimal The percentage utilization for the sequence developed using the FCFS rule = decimal places). % (enter your response as a percentage rounded to two 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) 1 (2) 2 (3) 3 (4) 4 The average tardiness (job lateness) for the sequence developed using the SPT rule = days (round your response to two decimal places). The average completion time (flow time) for the sequence developed using the SPT rule = places) days (round your response to two decimal The percentage utilization for the sequence developed using the SPT rule = % (enter your response as a percentage rounded to two decimal places). c) Using the LPT (longest 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 (5) 1 (6) 2 3 (8) 4 The average tardiness (job lateness) for the sequence developed using the LPT rule = days (round your response to two decimal places). days (round your response to two decimal The average completion time (flow time) for the sequence developed using the LPT rule = places) The percentage utilization for the sequence developed using the LPT rule = decimal places). % (enter your response as a percentage rounded to two d) Using the EDD (earliest due date) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received): Sequence Job (9) 1 (10) 2 (11) 3 (12) 4 The average tardiness (job lateness) for the sequence developed using the EDD rule = days (round your response to two decimal places). days (round your response to two decimal The average completion time (flow time) for the sequence developed using the EDD rule = places). The percentage utilization for the sequence developed using the EDD rule = decimal places). % (enter your response as a percentage rounded to two e) Using the Critical Ratio (CR) scheduling rule for sequencing the jobs, the order is: Sequence Job (13) (14) 2 (15) 3 (16) 4 The average tardiness (job lateness) for the sequence developed using the CR rule = days (round your response to two decimal places). days (round your response to two decimal The average completion time (flow time) for the sequence developed using the CR rule = places) % (enter your response as a percentage rounded to two decimal The percentage utilization for the sequence developed using the CR rule = places)
