- Drivers are trained in a process with two resources. The processing times for the resources are 32 and 140 hours. The first resource has 1 worker and the second resource has 5 workers. Demand occurs at the rate 0.025 Drivers per hour. Instruction: Round your answer to one decimal place. What is the implied utilization (%) of the second resource? %arrow_forwardIn order to meet holiday demand, Penny's Pie Shop requires a production line that is capable of producing 50 pecan pies per week, while operating only 40 hours per week. There are only 4 steps required to produce a single pecan pie with respective processing times of 5 min, 5 min, 45 min and 15 min. a. What should be the line's cycle time? minutes per pie. (Enter your response as an integer.) b. What is the smallest number of workstations Penny could hope for in designing the line considering this cycle time? c. Suppose that Penny finds a solution that requires 3 stations. What would be the efficiency of this line? %. (Enter your response rounded to two decimal places.) stations. (Enter your response rounded up to the next whole number.)arrow_forwardBalancing a process with a fixed sequence of activities will achieve a higher average labor utilization than balancing a process with no fixed sequence of activities.

- A machine operates with the following production cycle: 15 minutes of setup,45 minutes of production. While in production the machine produces 2 parts per minute.What is the capacity of the machine in parts per minute?arrow_forwardIn the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 14.35 hours. The time in the welding operation is spent as follows: 3 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setup of the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 2 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 2 hour waiting for the setup of the welding machine, 0.35 hour waiting for the other pieces of the batch to go through welding, 0.25 minute at the welding machine, and 2 hour waiting for the transfer to the next department. (Round your percentage answer to 4 decimal places.) Determine the exact flow time. What is the value-added percentage of the flow time? percentarrow_forwardFor a particular process, suppose the bottleneck cycle time is 40, and the raw processing time is 100. What is the minimum number of customers that must be in the system in order for the lead-time (LT) to exceed the raw processing time? Round to one decimal place.arrow_forward
