If the time standard is 0.7293 minutes per unit per machine. productivity is expected to be 85%, and the takt time is 0.116 minutes per unit. What is the number of machines that will be needed if the job is to be done in 8 hours on one shift with no overtime? (NOTE: you must have an integer number of machines.) Do NOT inlcude units such as "machines."

Assuming a workstation where one operator is assigned four machines. Previous work measurement studies have shown that the machine operates 75 percent of the time unattended, and the operator attention is required at irregular intervals for about 25 percent of the time. Assume a total shift time of 8 hours. How many units per day could be produced by this workstation if each machine can produce 70 units per hour running? Write your answer to 2 decimal places. Question 5

Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 4.0 per hour. It will take Benny an average of 8 minutes to give a haircut. Based on these figures, find the following: a. The average number of customers waiting. Note: Round your intermediate calculations to 3 decimal places and final answer to 2 decimal places. Average number of customers waiting b. The average time a customer waits. Note: Round your answer to 2 decimal places. Average waiting time minutes

(PowerToys) PowerToys Inc. produces a small remote-controlled toy truck on a conveyor belt with nine stations. Each station has, under the current process layout, one worker assigned to it. Stations and processing times are summarized in the following table: Station Task Processing Time (seconds) 1 Mount battery units 75 2 Insert remote control receiver 85 3 Insert chip 90 4 Mount front axle 65 5 Mount back axle 70 6 Install electric motor 55 7 Connect motor to battery unit 80 8 Connect motor to rear axle 65 9 Mount plastic body 80   a. What is the bottleneck in this process? b. What is the capacity, in toys trucks per hour, of the assembly line? c. What is the direct labor cost for the toy truck with the current process if each worker receiver $15/hour, expressed in dollars per toy truck? d. What would be the direct labor cost for the toy truck if work would be organized in a work cell, that is, one worker performs all tasks? Assume that the processing times would remain unchanged…
