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 48 units per hour.
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?
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 process flow in Figure 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.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?

Hi all, I do not know how to answer this questions. Please review and advise. Thank you
The following flow chart shows the entire manufacturing process at KD Manufacturing, which consists of six independent operations processes (i.e. sawing, sanding, drilling, reshaping, welding, and assembly). The entire process flow starts with the input of three different parts, Part I, Part II and Part III, each entering a different input line. Three parts meet later for the welding, whichever welding station is available (two identical welding stations work independently). After welding is completed, the product is sent to one of the three assembly stations (which are in parallel). The chart also shows the processing time per unit (in minutes) for each operation. Each of sawing, sanding, drilling and reshaping stations is handled by a different worker. Two workers handle welding, each at one welding station. Another three workers handle the assembly process independently, one at each assembly station. To improve the capacity of the entire manufacturing process, the manager decides to…
given information: which step is in bottleneck=30 min for tan leather 60/30=2 briefcases per hr are processed at the bottleneck workstation per hour throughput time of the overall process Throughput = 75 minutes PLEASE answer the following 3 questions: If the manufacturing facility operates 8 hours per day, 250 days a year, what is the annual capacity of this manufacturing process. Assume the company decides to hire additional workers in order to duplicate the bottleneck step identified in part a so that there are 3 of these workstations instead of 1. Redraw the diagram showing the flow of the revised process. Answer parts a through d again based on the new process created in part e?
Explain how having more work-in-process inventory can improve the efficiency of a process. How can this be bad?
A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). A) is the bottleneck. b) The bottleneck time isminutes per unit (round your response to two decimal places). c) The throughput time of the overall system is enter your response here minutes (round your response to two decimal places). D) If the firm operates 8 hours per day, 20 days per month, the monthly capacity of the manufacturing process isunits (enter your response as a whole number).

Tailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwindshoe, which sells for $210, contains both gas- and liquid-filled compartments to provide morestability and better protection against knee, foot, and back injuries. Manufacturing the shoesrequires 10 separate tasks. There are 400 minutes available for manufacturing the shoes inthe plant each day. Daily demand is 60. The information for the tasks is as follows: Task Performance Time (In minutes) Task Must Follow This task A 1 ___ B 3 A C 2 B D 4 B E 1 C.D F 3 A G 2 F H 5 G I 1 E,H J 3/25 I 1. What is the theoretical minimum number of work stations required to satisfy this output rate? 2. Allocate the tasks to work stations taking into consideration the precedence requirements and usingthe LOT rule to break ties between feasible tasks.
The diagram below shows a system that includes 7 operations with their capacities given as units/hr. What is the capacity (units/hr) of this system? Write the steps out manually please
