We discussed this 6-job, 4-machine job shop scheduling problem using the MWKR dispatching rule in the class: Operations Job i 1 2 3 4 1 6/A 8/B 13/C 5/D 2 4/A 1/B 4/C 3/D 3 3/D 8/B 6/A 4/C 4 5/B 10/A 15/C 4/D 3/A 4/B 6/D 4/C 6 4/C 2/A 4/B 5/D If the due dates for the six jobs are di 40, d2 = 60, d3 45, d4 = 50, ds = 55, d6 = 60, respectively, use the CR (Critical Ratio) dispatching rule to schedule these 6 jobs, and draw a Gantt chart for your result. What is Cmax in the result? your steps in detail in this question) (Notice: Show
