Question 1 Part (A) 1 D 2 B 3 C 4 A or C 5 A 6 D Part (B) Auto assembly L Auto repair center J Performing a surgery J Making different types of donuts. B Making petroleum from crude oil C Flour production C Question 2 What is the cycle time at stage 2? 1/(1/4+1/6) = 2.4 [min / unit] Which stage is the bottleneck? Stage 3 What is the minimum TPT? 15+7 = 22 min Question 3 Processing times for the two stage process shown to the right are in minutes. Calculate capacity of each stage in units per hour and determine the bottleneck stage. Capacity Stage 1 : (1/12+1/5)*60 = 17 [units / hr] Capacity Stage 2 : (1/4+1/15)*60 = 19 [units / hr] Bottleneck : Stage 1 (1) What is the minimum TPT? : 5+4 = 9 [min] (2) Using the Gantt chart below: Schedule a job on M1 every 15 minutes starting at time 0. Schedule a job on M2 every 5 minutes starting at time 0. Jobs on M1 go to M4; jobs on M2 go to M3. Plot this schedule for the first 6 jobs (J1 and J5 starting on M1 and J2-J3-J4-J6 starting on M2). If you cannot draw last two jobs completely, that’s fine.(4 points) 1 2 3 4 5
