Consider a balanced line consisting of five single-machine stations with exponential process times. Suppose the utilization is 75 percent and the line runs under the CONWlP protocol (i.e., a new job is started each time a job is completed). a. What is the WlP level in the line? b. What is the cycle time as a percentage of To? c. What happens to WIP, CT, and TH relative to the original system if you make each of the following changes (one at a time)? i. Increase the WIP level ii. Decrease the variability of one station iii. Decrease the capacity at one station iv. Increase the capacity of all stations

I already find a. I need help with b Bill's Barbershop has two barbers available to cut customer's hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow below shows that all customers go through steps B1 and B2 and then can be served at either of the two barbers at step B3. The process ends for all customers at step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer. b. What single activity is the bottleneck for the entire process? B what?
Consider a two-station production line. Station 1 consists of a single machine with an average processing times of 1 hours per job, while Station 2 have two parallel machines which are identical with average processing times of 2 hours per job. What are the rate of the bottleneck and average raw process time for this line? rb = 1 parts/hour; To=2 hours. rb = 1 parts/hour; To=3 hours. rb = 0.5 parts/hour; To=2 hours. rb = 0.5 parts/hour; To=3 hours.
Bill’s Barbershop has two barbers available to cut customers’ hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other.

The numbers in parentheses indicate the minutes it takes that activity to process a customer.a. How long does it take the average customer to complete this process?b. What single activity is the bottleneck for the entire process?c. How many customers can this process serve in an hour?
Explain how having more work-in-process inventory can improve the efficiency of a process. How can this be bad?
a) Balance this operation using the shortest operation time rule and compute the efficiency of the line. (10%)b) Discuss how this balance could be improved. Is it possible to improve this balance to 100%? (10%)
A firm uses a serial assembly system and needs answers to the following: An output of 900 units per shift (7.5 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 30 seconds. What is the required cycle time for such a system?
Imagine you could take a tour of the Tesla plant. To prepare for this tour, draw a simple process flow diagram of the operation. What is the cycle time of the process (assume two shifts of 8 hours each and 5 days a week of operation)? What is the flow time? Where in the process do you expect to encounter inventory? How many cars are you likely to encounter as work in progress inventory?
Students are going through a three-step process to obtain their ID cards. Each student will first spend 4 minutes at the (only one) registration desk. After that, he/she will visit one of three stations to have his/her picture taken, which takes 10 minutes on average. Finally, there is one machine that prints ID cards, and it takes 2 minutes to print a card. The demand rate is 12 students/hour. The process just completes serving a student. How long does it take to finish serving the following 10 students? Answers: a) 30min b) 40min c) 50min d) 60min
If you can hire an additional worker in order to improve the process capacity you should assign the worker to ?
The three-station work cell at Pullman Mfg., Inc. is illustrated in the figure below. It has two machines at station 1 in parallel (i.e., the product needs to go through only one of the two machines before proceeding to station 2). a) The throughput time isminutes (enter your response as a whole number). b) The bottleneck time of this work cell isminutes per unit (enter your response as a whole number) c) is the bottleneck station. If the firm operates 11 hours per day, 6 days per week, the weekly capacity of this work cell isunits (enter your response as a whole number).
upervisor Tom Choi at Tempe EquipmentCompany is concerned that material is not arriving aspromptly as needed at work cells. A new kanban system hasbeen installed, but there seems to be some delay in getting thematerial moved to the work cells so that the job can beginpromptly. Choi is interested in determining how much delaythere is on the part of his highly paid machinists. Ideally, thedelay would be close to zero. He has asked his assistant todetermine the delay factor among his 10 work cells. The assistant collects the data on a random basis over the next 2 weeksand determines that of the 1,200 observations, 105 were madewhile the operators were waiting for materials. Use a 95% confidence level and a {3% acceptable error. What report does hegive to Choi?
Panini, a popular sandwich shop, offers 3 types of sandwiches: grilled vegetables, grilled chicken, and pastrami. Demand (sandwiches per hour) are Grilled Vegetables = 25, Grilled Chicken = 15, and Pastrami = 10. There are up to five steps in the process of making sandwiches, listed below with processing times. Step Grilled Vegetables Grilled Chicken Pastrami 0.75 minutes 0.75 minutes 0.75 minutes 0.75 minutes 1.4 minutes 1.4 minutes - - - - 3 minutes 3 minutes 2 minutes 2 minutes 2 minutes 2 minutes 0.5 minutes 0.5 minutes 0.5 minutes 0.5 minutes Only 50 percent of customers want their sandwich toasted, no matter which sandwich is ordered. Suppose Panini employs 1 worker at each step. Instructions: Round all answers to 1 decimal place. What is the implied utilization of each of the five steps in this process?
