A bottling plant fills 2,400 bottles every two hours. The lead
time is 50 minutes and a container accommodates 80 bottles. The
safety stock is 30 percent of expected demand. How many kanban
cards are needed? (Round up your answer to the next whole
number.)
Number of kanbans = DL(1 + S)/C
D = Average number of units demanded over some time period
L = Lead time to replenish an order (expressed in the same units as demand)
S = Safety stock expressed as a percentage of demand during the lead time
C = Container size
D = If the average number of units demanded is 2400 and the time period is 2 hours, then that's the same as 1200 in an hour, 1200 in 60 minutes, 20 in one minute.
L = 50
S = 0.3
C = 80
Number of kanbans = 20 * 50 (1 + 0.3) / 80 = 16.25

JIT /Lean - Kanban: Daily demand for a product is 200 units. The production lead time (wait time + production time) for a container is 2 days. A 1-day safety stock is kept. How many kanban containers will be needed if each container holds 50 units? [Show calculations.]
Transmissions are delivered to the fabrication line four at a time. It takes one hour for transmissions to be delivered. Approximately four vehicles are produced each hour, and management has decided that 50 percent of expected demand should be maintained as safety stock. How many kanban card sets are needed? (Round up your answer to the next whole number.) Number of kanban card sets
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 2,600 units. The production lead time is 6 days (this includes processing time, transport time, and waiting time). Management has decided to have 2 day(s) of safety stock One container fits 350 units How many kanban containers will be needed to support this system? (Round up to next whole number). containers
Meritor 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 four per container. Meritor implements these suggestions and the result is that the muffler assembly fabrication cell now averages approximately 30 assemblies per hour, and the catalytic converter assembly cell can now respond to an order for a...
Meritor, a company that makes muffler assemblies for the automotive industry, is committed to the use of kanban to pull material through its manufacturing cells. Meritor has designed each cell to fabricate a specific family of muffler products. Fabricating a muffler assembly involves cutting and bending pieces of pipe that are welded to a muffler and a catalytic converter. The mufflers and catalytic converters are pulled into the cell based on current demand. The catalytic converters are made in a...
