For a particular operation, the setup time is 10 minutes and the run time is 50 minutes to produce a standard lot of 40 parts. It takes three additional hours to circulate a container of parts after production is completed. The demand rate is 20,000 parts per month. There are 160 production hours in a month.a. How many standard containers are needed?b. What is the takt time of this process?

- The following information describes a manufacturing system: Daily demand is 1,025 units. Replenishment lead time is 1.5 days. A 2.5 day safety stock is desired. Products are stored in containers that hold 940 units. How many kanban containers are needed for this system?arrow_forwardMeritor is so pleased with the outcome from previous suggestions that the consultants are invited back for more work. The consultants now suggest a more complete robotic automation of the making of muffler assemblies and also a reduction in container size to eight per container. Meritor implements these suggestions and the result is that the muffler assembly fabrication cell now averages approximately 32 assemblies per hour, and the catalytic converter assembly cell can now respond to an order for a batch of catalytic converters in one hour. The safety stock remains at 12.5 percent. How many kanban cards are needed? (Answer in Appendix D)arrow_forward. 4. It takes Susan 30 minutes to solder 10 circuit boards to fill a container and 2 minutes to transport the container to the next station, where John works. John's process takes about 45 minutes. The facility uses a safety factor of 10 percent. Currently, 5 kanbans rotate between Susan and John's stations. What is the approximate demand for circuit boards? 5. Bill works as a sorter for UPS. He can sort a tub of 50 packages in 20 minutes. He typically sorts 100 packages an hour. A truck arrives with more tubs each hour. UPS uses a safety factor of 5 percent. How many kanbans are needed for the package- sorting operation?arrow_forward
- The welding department supplies parts to the final assembly line. Management decides to implement a kanban system and has collected the following data: The daily demand is 2000 units. The production lead time is 4 days (this includes processing time, transport time, and waiting time). Management has decided to have 1 day of safety stock. One container fits 400 units. How many kanban containers will be needed to support this system?arrow_forwardHaving safety stock of raw materials to protect against quality is an example of “Mura”. True or falsearrow_forwardnorth end coffee roasters roast 300bags of coffee per day in three shifts at an average rate of 63 bags/hour. during the first shift, 100bags of coffee are roasted at 63bags/hour and the next 100 bags are roasted at 72 bags/hour in the second shift. Q- after roasting each bag of coffee is sealed and labelled at the packaging stage at a rate of 90 bags/hour. what is the average rate of production for the entire process pf roasting and packaging coffee beans at north end?arrow_forward

True or False?arrow_forward
- Please do not give solution in image format thankuarrow_forwardShorter production runs and multiple configurations of products do not work well in traditional manufacturing settings. Shorter runs require less material on the line. Most manufacturers still bring a full pallet to the line when needing only a third of the material on the pallet. As multiple product models flow through the assembly line, more pallets with parts for each model fill the work cell. These are necessary to accommodate quick changeovers on the line. The result is a high level of chaos. Aisles become more congested as traffic bringing (and returning) material to the line increases. Workers must use more steps to access the correct component for each model. The possibility of workers attaching the wrong material for the product model increases. Finally, safety issues rise. The good news is it is possible to reduce excess inventory and still meet production goals. With this regard, 1.1 Discuss how product defect becomes a waste in the production process. 1.2 Discuss some…arrow_forwardAn assembly station is asked to process 100 circuit boards per hour. It takes 20 minutes to receive the necessary components from the previous work station. Completed circuit boards ae placed in a rack that will hold 10 boards. The rack must be full before it is sent on to the next work station. If the factory uses a safety factor of 10%, how many kanbans are needed for the circuit board assembly process?arrow_forward
