- In a large microelectronics plant, the assembly cell for circuit boards has a demand for 250 units an hour. Two feeder cells supply parts A and B to the assembly cell (one A and one B for each board). Standard containers that look like divided trays are used. A container will hold 24 As or 10 Bs. It takes 10 minutes to fill up a container with As and 24 minutes to fill up a container with Bs. Transit time to the assembly cell is 5 minutes for both A and B. No safety factor is used. Set up a kanban control system for the assembly process.In a large microelectronics plant, the assembly cell for circuit boards has a demand for 300 units an hour. Two feeder cells supply partsA and B to the assembly cell (one A and one B for each board). Standard containers that look like divided trays are used. A container will hold 22 As or 13 Bs. It takes 13 minutes to fill up a container with As and 22 minutes to fill up a container with Bs. Transit time to the assembly cell is 5 minutes for both A and B. No safety factor is used.

- 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. 2340.00Roedel Electronics produces tablet computer accessories, including integrated keyboard tablet stands that connect a keyboard to a tablet device and holds the device at a preferred angle for easy viewing and typing. Roedel produces two sizes of integrated keyboard tablet stands, small and large. Each size uses the same keyboard attachment, but the stand consists of two different pieces, a top flap and a vertical stand that differ by size. Thus, a completed integrated keyboard tablet stand consists of three subassemblies that are manufactured by Roedel: a keyboard, a top flap, and a vertical stand. Roedel's sales forecast indicates that 7,000 small integrated keyboard tablet stands and 5,000 large integrated keyboard tablet stands will be needed to satisfy demand during the upcoming Christmas season. Because only 500 hours of in-house manufacturing time are available, Roedel is considering purchasing some, or all, of the subassemblies from outside suppliers. If Roedel manufactures a…This is the time that it takes a unit to travel through theprocess from beginning to end. It includes time waitingin queues and buffers.

Set up akanban control system for the assembly process.ABC Apple Juice Company produces and markets fresh fruit juice. During the apple harvest season, trucks bring apples from the fields to the process plant during a workday that runs long hours from 7AM. On peak days, approximately 3,000 kg of apples are trucked in per hour. Trucks dump their contents in a holding bin with a storage capacity of 9,000 kg. When the bin is full, incoming trucks must wait until it has sufficient available space. A conveyor moves apples from bin to the processing plant. The plant is configured to process apples at the rate of 2,000 kg per hour. Trucks arrive uniformly between 7:00AM to 5:00PM. Each truck holds about 1,000 kg of apples. The truck drivers are paid at the rate of $10 per hour. As ABC makes fresh juice, it does not store apples. Processing plant starts at 10:00AM and ends when all the apples received during the day have been processed. It takes 2 hours to clean the empty plant that must be kept ready for the next day production. Trucks are owned…Consider two separate systems.
