Compute the capacity (i.e. processing rate) for each of the following scenarios. Convertyour answers to parts per hour.a. A four-station line with single-machine stations, where the average processing timesare 15, 20, 10 and 12 minutes, respectively.b. A three-station line where the number of machines at stations 1, 2 and 3 is 2, 6, and3, respectively; and the average processing times are 10, 24 and 18 minutes,respectively.
An output of 720 units per shift (7.40 hours) is desired for a new processing system. The system requires product to pass through four stations where the work content at each station is 26 seconds. What is the required cycle time for such a system? How efficient is your system with the cycle time calculated? Station 3 changes and now requires 50 seconds to complete. What will need to be done to meet demand (assume only 7.40 hours are available)? What is the efficiency of the new system?

The Avis Company is a car rental company and is located three miles from the Los Angeles airport (LAX). Avis is dispatching a bus from its offices to the airport every 3 minutes. The average traveling time (a round trip) is 27 minutes. a. How many Avis buses are traveling to and from the airport? Note: Round your answer to the nearest whole number. Number of Avis buses b. The branch manager wants to improve the service and suggests dispatching buses every 1.0 minute. She argues that this will reduce the average traveling time (a round trip) to 4.0 minutes. Is she correct? If your answer is negative, then what will the average traveling time be? average traveling time is minutes

A work cell in a local manufacturer has a workstation with 4 machines that form a line (Machine 1-Machine 2-Machine 3-Machine 4). Each unit needs to pass through each machine in order to be completed. Each machine has a production capacity of four units per hour. What is the process time of the work cell in minutes per unit? 15 4 8 16
Lou operates a cab service specifically tailored to provide safe and comfortable transportation for seniors in his town. He owns five cabs, each staffed by a dedicated driver. Upon receiving a service call, Lou promptly dispatches one of these drivers to pick up the customer. The operational details are as follows: • Each driver takes an average of 15 minutes to arrive at the customer's location after being dispatched. • The journey from the customer's pickup location to their destination averages 25 minutes. • Lou’s service receives an average of 2.5 calls per hour. For analytical purposes, you can assume that both the arrival of service calls (demand) and the service times have coefficients of variation (CV) equal to 1. (a) What is the average waiting time for a customer from the moment they place a service call to Lou until a cab arrives to pick them up? (For answering this question carefully think about different stages of processes, and what a customer is doing in each stage. It…
A work cell is required to make 100 computerized diagnostic assemblies (for installation into hybrid automobiles) each day. The cell currently works an eight hour shift, of which seven hours is available for productive work. These assemblies require five operations, with times of 1.5, 1.8, 1.4, 1.5, and 1.9 minutes each. What is takt time for this cell? How many workers will be needed?

The 4M company has a lathe as the centerpiece of the plant's work. The jobs arrive according to a Poisson process with an average rate of 2 per day. The processing time of each job is exponentially distributed with an average of 1/ 4 day. Since the jobs are large, if they are not in process they are stored in a warehouse some distance from the machine. However, to save time in bringing them in, the production manager proposes to add space for 3 in-process jobs in addition to the one on the lathe (the rest will continue to be stored). With this proposal, what proportion of the time will the space next to the lathe be adequate for the waiting jobs? Calculate your answer using the formulas available.
