A company is in the business of machining parts that go through various work centers. Suppose work center A feeds work center B with parts. The following times (in minutes) are given for each work center. A standard kanban container holds 50 parts that are transferred from work center A to work center B. The demand rate at work center B is four parts per minute. a. How many kanban containers are needed for this situation? b. If move time is cut in half, what does this do to the number of containers needed? How much will this change reduce inventory?
In a large microelectronics plant, the assembly cell for circuitboards has a demand for 200 units an hour. Two feeder cellssupply parts A and B to the assembly cell (one A and one Bfor each board). Standard containers that look like dividedtrays are used. A container will hold 20 As or 10 Bs. It takes10 minutes to fill up a container with As and 20 minutes tofill up a container with Bs. Transit time to the assembly cell is5 minutes for both A and B. No safety factor is used. Set up akanban control system for the assembly process.
Jason Carter works for a producer of soaps that come inpackages of 6 each. His job is to fi ll the packages with soap, andhe is expected to process 30 packages an hour. Th e facility whereJason works uses a kanban production system in which eachcontainer holds 5 packages of soap. It takes 20 minutes to receivethe packages he needs from the previous workstation. How manykanbans are needed for the fi lling process?

- Furniture Face Lift refinishes old wood furniture. Their process for refinishing chairs has 9 workers and 4 stations. Each chair starts at the Stripping station, then goes to Priming, then to Painting and finally to Inspection. Where there are multiple workers within a station, each worker works independently on his/her own chair. Assume inventory buffers are allowed between each station.

How many hours will it take them to complete these 10 chairs?(The accuracy should be of two digits after the decimal places.)arrow_forwardKanban. Work center A produces parts that are then processed by work center B. Kanban containers used by the work centers hold 100 parts. The overall rate of demand is 4.5 parts per minute at work center B. The table below shows setup, run, move,and wait times for parts at each of the work centers a. What is the minimum number of containers needed between these two work centers? b. Assume that two extra containers are available (at no extra cost). If these work centers use the two containers, what is the maximum parts per minute that could be expected to flow through these two work centers? Could the work centers handle a demand of 8.5 parts per minute?arrow_forwardA Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 16-minute setup. Once in production, the PCB machine requires only 0.19 minute per board. a. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per min)? b. Currently, the PCB machine produces 525 boards between setups. Given this operating process, what is the utilization of the PCB machine? c. Say the PCB machine produces 400 boards s between setups and demand is 2 boards per minute. Given the operating process, what is the avergae inventory of boards anf the PCB machine? d. Demand for boards occurs at the rate of 2 boards per minute. What is the smallest batch size such that the PCB machine does not constrain the flow rate through the process?arrow_forward
- You operate a process with three workstations; the cycle times are given below. A regular batch is 52 units and your production line runs 5 hours per day. Calculate how many hours lead time is required to ship a batch, assuming there are no orders ahead in the queue and there is no inventory to fill the order. Workstation 1 has a cycle time of 2 minutes per unit Workstation 2 has a cycle time of 3 minutes per unit Workstation 3 has a cycle time of 3 minutes per unit Select one: a. 1560.00 b. 8.00 c. 1560.00 d. 90.00 e. 2340.00arrow_forwardThe White Tooth Device Company is a manufacturer of high-end electric toothbrushes. For each toothbrush, there is a sequence of assembly steps performed by five workers. Each worker does two tasks. Inventory buffers are allowed between workers. (a) What is the capacity and cycle time of this process? (b) What is the idle time of each worker if the process operates at full capacity? (c) Suppose two workers could be hired, F and G, and they take the same time to complete tasks as the current five workers. F and G can be assigned to work on the same pair of tasks as one of the current workers. For example, F could be assigned tasks T1 and T2 (just like worker A) while G is assigned T5 and T6 (just like worker C). They cannot be assigned tasks that are currently assigned to two workers. For example, F cannot be assigned to tasks T2 and T3 (because they are currently being done by workers A and B). What is the capacity of this process with workers F and G included?arrow_forwardA company using a kanban system has an inefficient machine group. For example, the daily demand for part L105A is 3,000 units. The average waiting time for a container of parts is 0.8 day. The processing time for a container of L105A is 0.2 day, and a container holds 270 units. Currently, 20 containers are used for this item.a. What is the value of the policy variable, a?b. What is the total planned inventory (work-in-process and finished goods) for item L105A?c. Suppose that the policy variable, a, was 0. How many containers would be needed now? What is the effect of the policy variable in this example?arrow_forward

A total of 10 million cuft of dirt is needed to construct the dam. A bulldozer is usedto collect dirt for the dam. Then the dirt is moved via dumpersto the dam site. Only one bulldozer is available, and it rentsfor $100 per hour. Bectol can rent, at $40 per hour, as manydumpers as desired. Each dumper can hold 1,000 cu ft ofdirt. It takes an average of 12 minutes for the bulldozer toload a dumper with dirt, and each dumper an average of fiveminutes to deliver the dirt to the dam and return to the bulldozer. Making appropriate assumptions about exponen-tiality, determine how Bectol can minimize the total expected cost of moving the dirt needed to build the dam.arrow_forwardThe magnetic resonance imaging (MRI) unit of St Francis hospital has 2 MRI machines and sees two kinds of patients, "regular" patients and "contrast" patients. The regular patients don't need any special preparation before imaging but the contrast patients receive an injection of "dye" that enables the physicians to see the images more clearly. Regular patients require 15 minutes in an MRI machine whereas contrast patients take on average 25 minutes in an MRI machine. Over an 8-hour day, the MRI unit receives an average of 25 regular patients and 5 contrast patients. (a) What is the implied utilization (as a %) of the MRI unit? % (b) What are the actual and maximum flow rates through the MRI (patients per day)? regular contrast Actual flow rates Max flow rates.arrow_forward
