The analyst in XYZ Company wishes to assign a number of similar facilities to an operator, based on minimizing the cost per unit of output. A detailed study of the facilities reveals the following Loading machine standard time = 0.5 minute Unloading machine standard time = 0.5 minutes Power feed time = 2.00 minutes
Walk time between machines = 0.25 minutes Assume that the operator rate is $15 per hour and the machine rate is $20 per hour. Answer for the following: (Enter numeric values only) a. What is the ideal number of machines that can be assigned to an operator? (Answer in 1 decimal value) b. What is the maximum number of machines that can be assigned to an operator without creating machine idle time during the repeating cycle? c. What is the cost per unit produced of assigning machines without creating operator idle time? (use 3 decimal values) d. What is the cost per unit produced of assigning machines without creating machine idle time? (use 3 decimal values)
e. What assignment minimizes the cost per unit produced? f. What is the minimum number of machines that can be assigned to an operator without creating operator idle time? g. If 20 machines are to be allocated, how many operators are required?
