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$)$:

An Alabama lumberyard has four jobs on order, as shown in the following table. Jobs are logged as they arrive. Today is day $1$ on

the yard's schedule. In what sequence would the jobs be ranked according to the decision rules on the left:

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$)$:
