Consider the Chipotle example we discussed in the class. But this time, both workers M1 and M2 need a longer time to finish their tasks (the activity times change to 90 seconds and 60 seconds, respectively)
a) Calculate the following design parameters for this process: Cycle time (CT) for Stage 1 sec / unit CT for Stage 2 sec / unit Bottleneck Stage: Process Designed CT sec / unit Process Capacity units / hour
b) Customers arrive to this Chipotle in the following way: At time 0, 120 sec, 240 sec, 360 sec, ..., two customers arrive together, and M1 and M2 each takes a customer to serve. At time 60 sec, 180 sec, 300 sec, one customer arrive and M2 (the faster worker) serves him/her. Draw the Gantt chart from time 0 to time 340 sec. Each grid in the following chart represents 10 seconds. You can extend the below chart as needed.
c) Under the arrival schedule given in (b), calculate the following run-time parameters: Demand Rate units/hour Flow Rate units/hour Actual Cycle Time sec/unit WIP for M1 units WIP for M2 units WIP for Buffer units WIP for M3 units Total WIP units Flow Time sec
