The production manager at the Knox Machine Company is preparing a priority schedule

for one of the fabrication shop. The production manager has heard about six dispatching

rules: $(1)$ shortest operation next $($SON$),(2)$ earliest due date $($EDD$),(3)$ earliest operation

due date $($EODD$),(4)$ least order slack, $(5)$ Least slack per operation, or $(6)$ critical ratio

$($CR$).$ The current shop status of the company is given below.

Assume $0\mathrm{.}5$ day move and queue time for each remaining operation, and current time is $0.$
