$ks,1,2,3,$ and $4,$ are waiting on a loading dock at XYZ Company that $1$ gle service bay. The trucks are labeled in the order that they arrived at ume the current time is $1$:$00$ P$.$M$.$ The times required to unload each tru

imes that the goods they contain are due in the plant are given in table.

$\backslash$table$[[$Truck Unloading Time $($minutes$),$Time Material Is Due,$],[1,20,1$:$25$ P$.$M$.],[2,14,1$:$45$ P$.$M$.],[3,35,1$:$50$ P$.$M$.],[4,10,1$:$30$ P$.$M$.]]$

mine the schedules that result for each of the rules FCFS$,$ SPT$,$ EDD, and ach case compute the mean flow time, average tardiness, and number o s$.$

it solve for CR method.

er the information given in Problem $4.$ Determine the sequence that th should be unloaded in order to minimize

in flow time.
