Using the information presented in the following table, identify the processing

sequence that would result using priority rules $(1)$ MST$,(2)$ SPT$,(3)$ EDD, and $(4)$ CR$.$ For each

priority rule, determine $(1)$ average flow time, $(2)$ average hours late, and $(3)$ average WIP. For

each factors, which priority rule superior to the others? $($Hint: First determine the total job time

for each job by calculating the total processing time for the job and then adding in the setup

time All times are in hours.$)$
