1 2 t=1 t=1.5 5 4. A production process requires 5 different types of machine and the current layout with operation times in minute is given. Shrinkage rates are 5%, 3%, 6%, 4%, and 1% for machines 1, 2, 3, 4, and 5. The output should be (X+10)*10 units. Personal allowance for all the operators is given 3%. Suppose that 4 hours are available for this production, a. Calculate the required number of machines. b. Calculate each machine's idle time. 3 4 t=2 t=1 ta 1.5 1 2 t=1 t=1.5 5 4.
