data given in the example problem in the section on manufacturing lead time. It is decided to overlap operations A and B by splitting the lot of 100 into two lots of 70 and 30. Wait time between A and B and between B and stores is eliminated. The move times "remain" the same. Setup on operation B cannot start until the first batch arrives. Calculate the manufacturing lead time. How much time has been saved? Select the best answer: O a. Total Manufacturing time: 21.75, Time saved: 13 b. Total Manufacturing time: 27, Time saved: 8 c. Total Manufacturing time: 35, Time saved: 13 d. Total Manufacturing time: 25, Time saved: 10
