Question 10

There are 5 jobs (A,B,C,D,
E)that need to be completed in a work center.The due dates are the 10th,13th,9th,20th,and 15th respectively with process times of 7,12,7,20,and 10 respectively as well.If today is the 1st of the month calculate the critical ratio for each and use this value to sequence the jobs in the order they should be started.

Accepted Answer

A = (10 - 1)/7 = 1.29 B = (13
