You have been called in as a consultant to set up a kanban control system. The first thing to do is to determine the number of kanban card sets needed. Your research shows that the expected demand during lead time for a particular component is 150 per hour. You estimate the safety stock should be set at 25 percent of the demand during lead time. The tote trays used as containers can hold 8 units of stock, and the lead time it takes to replenish an order is 2 hours. You found that the number of kanban cards needed is 47. Your client now tells you that they miscalculated the demand and the true demand is 300 per hour. All other things remain the same. What is the most appropriate answer from the choices below?
A) Number of kanban cardsets will stay the same
B) Number of kanban cardsets will decrease.
C) Number of kanban cardsets will be 94
D) Number of kanban cardsets will be 47
E) Number of kanbancardsets will be 23.5 (rounded to 24).

The number of kanban card sets is calculated using the formula: (Demand during lead time + Safety stock) / Container size. With the new demand of 300 per hour, the demand during lead time is 300 * 2 = 600. Safety stock is 25% of 600, which is 150. Therefore, the total demand is 600 + 150 = 750. Dividing by the container size of 8 gives 750 / 8 = 93.75, which rounds to 94 kanban card sets.
