The Honda dealership at your city forecasted that it could sell around 500 cars in the next year. The annual carrying cost of a car is ¥500,000, and the ordering cost which involves order processing and transportation is ¥300,000. Once an order is made, it will take 20 days to receive the cars. Determine the optimal order size, the minimum total inventory cost, the optimal time between orders, the number of orders, and the reorder point. Assume 365 days in a year.
