Practice Questions

Question 1

Which scheduling approach plans operations by starting from the job due date and working backwards to determine start times?

Question 2

Which shop floor environment is characterized by high mix and low volume production with unique job routings, making scheduling most challenging?

Question 3

In a two-machine flow shop with jobs A, B, and C having processing times on Machine 1 and Machine 2 as follows: A(4 h, 2 h), B(1 h, 3 h), C(5 h, 1 h), which sequence minimizes makespan according to Johnson’s rule?

Question 4

Consider three jobs with processing time P and due date D: J1(P=4, D=14), J2(P=2, D=9), J3(P=3, D=10). Using the Critical Ratio rule $CR=(D-T)/P$ at current time $T=0$, what is the correct job sequence to minimize lateness?

Question 5

Which formula correctly defines the Slack per Remaining Operations (S/RO) sequencing rule?
