A two station nurses clinic operates where you must visit the first station before the second. The CV of a cycle time for this is .75. Average process time for the first nurses station is 15 minutes. Average process time for the second nurses station is 9 minutes. a. Find the standard deviation of the overall cycle time b. Assume the std dev of the first nurses station is to be twice that of the second. What would the new coefficient of variation be if the standard deviation of the second nurse station is reduced by 60%?
For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (this includes fringe benefits). Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each. a. Should Operation 1 or Operation 2 be recommended? b. What is the basic tradeoff in this problem?

Hammond Inc. has analyzed the setup time on its computer-controlled lathe. The setup requires changing the type of fixture that holds a part. The average setup time has been 135 minutes, consisting of the following steps: Step Time (in minutes) Turn off machine and remove fixture from lathe 13 Go to tool room with fixture 15 Record replacement of fixture to tool room 18 Return to lathe 20 Clean lathe 17 Return to tool room 20 Record withdrawal of new fixture from tool room 12 Return to lathe 15 Install new fixture and turn on machine 8 Total setup time 138 Why should management be concerned about improving setup time? What do you recommend to Hammond Inc. for improving setup time? How much time would be required for a setup, using your suggestion in (b)?
A machine makes two components; call them types A and B. It takes 630 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 4 seconds, or 15 units per minute. Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. In that case, what is the capacity of the machine in component pairs per minute, where a component pair is one unit of A and one unit of B? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the utilization of the machine? Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. What is the average inventory of B components? If the production schedule could be adjusted with…

Consider the following data: observed time/unit = 6 minutes Performed Rating = 110% Allowance = 25% of normal time shift duration = 6hours Calculate the standard outputs/shift 2) An employee processes 6 insurance policies/day. The company employs 4 employees,each working 8 hours/day.Employee wage/day=620 dollar and daily overhead expanse = 480 dollar.The company is now considering a purchase of new technology which will enable each employee to process 9 insurance policies/day with an increase of 65 dollars in the daily overhead expanse.The company is aiming for at least 30 percent increase in both labor and multifactor productivity after this purchase.Should the company go for this purchase?
Heizer and Render advises that when analyzing and designing processes to transform resources into goods, the followingquestions should be asked:- Is the process designed to achieve competitive advantage in terms of differentiation, response or low cost?- Does the process eliminate steps that do not add value?- Does the process maximize customer value as perceived by the customer?- Will the process win orders?A Time-Function Map is similar to a flow process chart, but with time added to the horizontal axis. With time-function mapping,notes indicate the activities and arrows indicate the flow direction, with time on the horizontal axis.
