There are $4$ Mass Production Models M$1,$ M$2,$ M$3,$ and M$4$ taking $3,5,2,$ and $4$ hours of manufacturing time, respectively and their respective due dates to the distributor are $4,10,9,$ and $7.$ Which priority rule from SPT$,$ FCFS$,$ CR$,$ and EDD you would use while sequencing and why? Also, compute the Average Job Completion Time, Average Utilization Factor, and Average Job Lateness Duration for each of the priority rule. $(10,$ CO$2/$PO$2)$

In manufacturing, sequencing jobs on the production line is crucial for optimizing efficiency and meeting customer deadlines. Different priority rules determine the order in which jobs are processed based on various criteria such as duw dates or processing times. Four common priority rules used in production scheduling are EDD $($Earliest due date$),$ SPT$($Shortest processing time$),$ FCFS$($ First Come First Serve$),$ and CR$($Critical Ratio$)$:
