Question 2 (2+2+2+2=8 points) c) What is the average throughput time, i.e., flow time (in minutes)? Round the answer to 2 decimal places if required. M1 M3 8 3 (Hint: Every 10 minutes, 3 job come to the process (1 job to M1, 2 jobs to M2). To get the average flow time, you need to calculate the flow time for each of the three jobs and then do an average.) We have a process shown in the right figure. (M1- M4 are names for four machines. The numbers are activity times in minutes). Consider a schedule: schedule a job on M1 every 10 minutes, starting at time 0; schedule a job on M2 every 5 minutes starting at time 0. Jobs finished on M1 go to M4; jobs finished on M2 go to M3. M2 M4 5 10 a) Plot this schedule for the first 6 jobs in the following Gantt chart. The first job and the 5th job start on M1. The second, third, 4th, and the 6th jobs start on M2. The first block of job 1-5 is plotted for you. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 d) Is the process demand- or supply-constrained? (Explain your answer) M1 11 M2 M3 M4 Machine WIP (units) b) Find the WIP on each machine and complete the table to the right. M1 M2 M3 M4 Total
