Because of shipping andhandling costs, each order must be for 12 units . Because of the time it takes to receive an order,the company places an order every time the present stock drops to 6 units. It costs $120 to placean order. It costs the company $75 in lost sales when a customer asks for a computer and thewarehouse is out of stock. It costs $5 to keep each computer stored in the warehouse. If a customercannot purchase a computer when it is requested, the customer will not wait until one comes in butwill go to a competitor. The demand for computers and the time required to receive an orderonce it is placed (lead time) has the following probability distribution: The company has 10 computers in stock. Orders are always received at the beginning of theweek. Note that a lead time of 2 weeks imply that an order placed at the end of week one willarrive at the beginning of week 4.Requireda) Construct the appropriate random…arrow_forwardJean Clark is the manager of the Midtown Saveway Grocery Store. She now needs to replenish her supply of strawberries. Her regular supplier can provide as many cases as she wants. However, because these strawberries already are very ripe, she will need to sell them tomorrow and then discard any that remain unsold. Jean estimates that she will be able to sell 10, 11, 12, or 13 cases tomorrow. She can purchase the strawberries for $3 per case and sell them for $8 per case. Jean now needs to decide how many cases to purchase. Jean has checked the store’s records on daily sales of strawberries. On this basis, she estimates that the prior probabilities are 0.2, 0.4, 0.3, and 0.1 for being able to sell 10, 11, 12, and 13 cases of strawberries tomorrow. 1.
