It purchases kitty litter for $13.00 per bag The following information is available about these bags: > Demand 85 bags/week >Order cost $60.00/order > Annual holding cost = 35 percent of cost > Desired cycle-service level 80 percent > Lead time = 4 weeks (24 working days) > Standard deviation of weekly demand = 15 bags > Current on-hand inventory is 320 bags, with no open orders or backorders. a. Suppose that the weekly demand forecast of 85 bags is incorrect and actual demand averages only 65 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? The costs will be $higher owing to the error in EOQ.

The lead time form the supplier is 1010 days, with a standard deviation of 33 days. It is important to maintain a 9898 percent cycle-service level to properly balance service with inventory holding costs.
