QUESTION 6

1. In problem MM3 on pg 225 of the Lean Thinking book, the cell represented for product A is formed by two machines. The setup time between operations can be considered null. The company works 5 days a week, 8 hours per shift, with 2 shifts per day. Calculate the Cycle Time (minutes) that fixes production cycle for Part A ONLY. Again, this is only for Part A.

   	A.	7 min
   	B.	10 min
   	C.	686 min
   	D.	480 min

Problem MM3 The cell represented in the following figure is formed by three ma- chines. The setup time between operations can be considered null, and both products have the same profit. The company works 5 days a week, 8 hours per shift, with two shifts per day. Product A Product B C2 (1) C1 (1) M3 C2 (1) OP4 (1 min/u) OP4 (6 min/u) M1 M1 M3 M2 OP3 (10 min/u) OP2 (1 min/u) OP3 (5 min/u) OP2 (2 min/u) M3 M1 OP1 (5 min/u) OP1 12 min/u) 1. Determine the maximum weekly production. 2. Calculate the cycle time of both products. 3. Show the M2-M1-M3 diagram, assuming a stable state.
