A supervisor has determined the expected processing times at a machine for a set of jobs and now wants to sequence them. Given the following information, do the following: a$-1.$ Determine the processing sequence using $(1)$ MST$,(2)$ SPT$,(3)$ EDD, and $(4)$ CR$.$a$-2.$ For each sequence, calculate the average days late, the average flow time, and the average WIP. $($Do not round intermediate calculations. Round the final answers to $2$ decimal places.$)$ b$.$ Which rule is best? has the lowest average flow time $\backslash$& average WIP, but have the lowest average days late.
