2. How many machines would be assigned to an operator for the lowest cost- operation when: /20 marks Loading and unloading time on one machine is 2.45 min Walking time to the next facility is 0.2 min Machine time (power feed) 5.25 min Operator rate is $22/h Machine rate is $12/h 1) Calculate the optimal ratio of machines to operators? 2) Calculate the number of machines at which the operator will have some idle time? 3) Calculate the number of machines at which the machines will have some idle time? 4) Calculate production rate per hour based on n1 (operator idle) 5) Calculate production rate per hour based on n2 (machine idle) 6) Calculate total cost per hour based on n1 7) Calculate total cost per hour based on n2 8) Calculate the cost per unit output based on n1 9) Calculate the cost per unit output based on n2 10) Choose the number of machines per operator with the lower cost per unit output 2.
