Compute Lead TimeBhojraj Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach,the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 30 parts. A partrequires 7 minutes in milling and 9 minutes in finishing. The move time between the two operations for a complete batchis 4 minutes.Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. Theoperating time is unchanged; however, the batch size is reduced to 2 parts and the move time is eliminated.Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional andlean manufacturing methods. If required, round percentages to one decimal place.Traditional Philosophy Lean Manufacturing PhilosophyValue-added timeNon-value-added timeTotal lead timeValue-added ratio (as a percent)X minX minmin%minminmin%

Gestalt, Inc. uses a kanban system in its automobile production facility in Germany. This facility operates 10 hours per day to produce the Jitterbug, a replacement for the obsolete but immensely popular Jitney Beetle. Suppose that a certain part requires 60 seconds of processing at machine cell 33B and an average container of parts averages 1.4 hours of waiting time there. Management has allowed a 12 percent buffer for unexpected occurrences. Each container holds 27 parts, and 5 containers are authorized. How much daily demand can be satisfied with this system? (Hint: Recall that p is the average processing time per container, not per individual part.) The average processing time per container of parts, p, is 0.045 day. (Enter your response rounded to three decimal places.) The average waiting time per container of parts, w, is day. (Enter your response rounded to two decimal places.)

Operations Management Hinge Manufacturing Company employs a Kanban system for a component part. The daily demand is 900 hinges. Each container has a wait time of 0.05/day and a processing time of 0.37 days. The Container size is 60 hinges and the safety factor (a) is 10%. A: How many Kanban card sets should be authorized? B: What is the maximum inventory of this hinge in the system?
Pauline Found Manufacturing, Inc., is moving to kanbans to support its telephone switching-board assembly lines. Determine the size of the kanban for subassemblies and the number of kanbans needed. Setup cost $30 Annual holding cost $125 per subassembly Daily production 30 subassemblies Annual usage 3,000 (50 weeks×5 days each×daily usage of 12 subassemblies) Lead time 12 days Safety stock 4 days' production Part 2 Kanban container size = enter your response here units (round your response to the nearest whole number).
A local hospital wants to set up a kanban system to manage its supply of blood with the regional blood bank. The regional blood bank delivers blood to the hospital each day with a one-day order lead time (an order placed by 6 P.M. today will be delivered tomorrow afternoon). Internally, the hospital purchasing group places orders for blood each day at 5 P.M.Blood is measured by the pint and is shipped in containers that contain six pints. For a particular blood type, the hospital uses an average of 12 pints per day. Due to the critical nature of a blood shortage, the hospital wants to carry a safety stock of two days’ expected supply. How many kanban card sets should the hospital prepare?
Cletus and Spike Company is implementing a Kanban system for a heated water bowl manufacturing line that produces 1,500 units in an eight-hour day. The heating element has a waiting time of 30 minutes and a processing time of one hour. The container size is 40 heating elements, and the safety factor is 15 percent. What is the maximum inventory of heating elements in the system?

You are asked to analyze the kanban system of LeWin, a French manufacturer of gaming devices. One of the workstations feeding the assembly line produces part M670N. The daily demand for M670N is 1,800 units. The average processing time per unit is 0.003 day. LeWin’s records show that the average container spends 1.05 days waiting at the feederworkstation. The container for M670N can hold 300 units. Twelve containers are authorized for the part. Recall that r is the average processing time per container, not per individual part.a. Find the value of the policy variable, a, that expresses the amount of implied safety stock in this system.b. Use the implied value of a from part (a) to determine the required reduction in waiting time if one container was removed. Assume that all other parameters remain constant.
Identify a service or a manufacturing process that you are familiar with, and draw a current state value stream map to depict its existing information and material flows.
A fabrication cell at Spradley’s Sprockets uses the pull method to supply gears to an assembly line. George Jitson is in charge of the assembly line, which requires 500 gears per day. Containers typically wait 0.20 day in the fabrication cell. Each container holds 20 gears, and one container requires 1.8 days in machine time. Setup times are negligible. If the policy variable for unforeseen contingencies is set at 5 percent, how many containers should Jitson authorize for the gear replenishment system?
In a lean system, work-in-process inventory is Question 34 options: eliminated entirely. reduced to reveal production problems, which can then be addressed. increased to prevent work stoppages due to production problems and smooth overall production. ignored because it has little effect on the availability of finished goods inventory.
