Formulas:

Critical Ratio for each job $=$ CR $=($Due Date Days$)/($Processing Time Days$)$

Average completion time $=($Sum of all flow times$)/($total no$.$ of jobs$)$

Percentage Utilization $=($Sum of all processing times$)/($Sum of all flow times$)$

Average no$.$ of jobs in the system $=($Sum of all flow times$)/($Sum of all processing times$)$

Average lateness $=($Sum of all late time$)/($Total no$.$ of jobs$)$

Thus, the appropriate job sequencing based on the above data and the appropriate sequencing rule is given as in the below sheet, along with the calculations for average tardiness, average no$.$ of jobs, average flow time. no$.$ of late jobs, maximum lateness, the ratio of average flow time to average no$.$ of jobs, and the optimal job sequence itself.
