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$)$:

$\backslash$table$[[$Sequence$,$Job$],[1,$A$],[2,$B$],[3,$C$],[4,$D$]]$

The average tardiness $($job lateness$)$ for the sequence developed using the FCFS rule $=0\mathrm{.}4$ days $($round your response to two decimal places$).$

The average completion time for the sequence developed using the FCFS rule $=2$ days $($round your response to two decimal places$).$

The percentage utlization 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$)$

$\backslash$table$[[$Sequence$,$Job$],[1,V$
