A medical equipment testing and calibration service is shown below. The customer usually brings the equipment to the service center. The service process requires service technicians to perform three process steps \# 1 to \#3. Each technician is cross-trained so they can perform any of the three steps. The inspector does step \#4 alone. After step \#4, two parallel work activities are performed. That is, a shipping clerk packs the work (step \#7), while simultaneously, a billing clerk prepares the invoice (step \#5), and the customer is contacted by phone for pick-up (step \#6). The average throughput is three equipment units per hour. The table below shows the work content of the process steps, activity times in minutes per unit, shared and non-shared work activities, and the type of resource required. There are three service technicians on duty, one inspector, one billing clerk, and one shipping clerk. The process for renewing a driver's license at the Archer County Courthouse is as follows. First, the clerk fills out the application; then the clerk takes the driver's picture; and finally, a typist enters the information into the computer system and processes the new license. It takes an average of six minutes to fill out an application, three minutes to take a picture, and eight minutes to process the new license. Due to county and state budget cuts, Archer County Courthouse now has only three clerks and two typists and expects to process 39 drivers/hour. What is the current labor utilization of each labor type? Do not round intermediate calculations. Round your answers to the nearest whole number. Labor utilization of clerks: % Labor utilization of typists: % Where is the bottleneck in this three-stage process? The ability of the system is limited to How might the job and process design be improved? The best way to help alleviate this bottleneck is by using work practices and technology to service rates. b. Suppose that the number of workers at each stage are as follows: What is the output rate at each stage? Round your answers to the Stage A: units/hour Stage B: units/hour Stage C: units/hour Stage D: units/hour Stage E: units/hour C. Where is the bottleneck in this process? The bottleneck is The production process shown below consists of five stages. The numbers in parentheses are the times in minutes to complete one unit before it moves on to the next stage. The demand rate is 38 units per hour. a. How many workers are needed at each stage if management wants a utilization of at least 80 percent? Round your answers up to the nearest whole number. Stage A: workers Stage B: workers Stage C: workers Stage D: workers Stage E: workers
