Demand in each period follows the same normal distribution (i.e., there is one demand distribution that represents demand in any single period). Assuming demand is independent acrossperiods, which of the following statements about mean demand over five periods is true? a. It equals the mean of demand over one period.b. It is greater than the mean of demand over one period but less than five times the meanof demand over one period.c. It equals five times the mean of demand over one period.d. It is even more than five times the mean of demand over one period.
Suppose that the newsvendor faces integer-valued demand and must choose an integer value of y. We make no assumptions about the demand distribution (other than that it is an integer) or about the relationship between h and p. Prove that y* is the smallest integer y such that F(y) ≥ (r − c)/(r − v) where F is the cdf of the demand distribution. (Hint: Consider calculating the cost difference between two consecutive integer values.)
A retailer uses the order-up-to model to manage inventory of an item in a store. The leadtime for replenishments is four weeks and it can place orders weekly. Weekly demand isPoisson with mean 0.10 unit. Its order-up-to level is five and unfilled demand is backordered. What is the coefficient of variation of its orders?

- The best quantity to order One of the formulas for inventorymanagement says that the average weekly cost of ordering, payingfor, and holding merchandise iswhere q is the quantity you order when things run low (shoes,TVs, brooms, or whatever the item might be); k is the cost ofplacing an order (the same, no matter how often you order); c isthe cost of one item (a constant); m is the number of items soldeach week (a constant); and h is the weekly holding cost per item(a constant that takes into account things such as space, utilities,insurance, and security).

The firm uses 190 grams of silver per week and purchases silver for $0.52 per gram from a supplier. Each time the firm orders silver from the supplier, the firm must pay a $11 order processing charge. The firm's annual holding cost percentage is 38%. Do not round intermediate calculations. Assume there are 52 weeks in a year and round your answer to two decimal places. If the jeweler orders 1,950 grams of silver with each order, what is the sum of the annual holding and ordering costs? dollars Please do fast ASAP fastarrow_forward
- Daily demand of a chemical at an oil refinery is normally distributed with a mean of 60 litres and a standard deviation of 7. The supplier reliably delivers the chemical by maintaining a constant lead time of 1 week. There are no delivery charges from the supplier. Sales occur throughout the year. An order placement requires one hour of an administrative employee who is paid $20 per hour. Receiving and storing a chemical shipment requires two workers to work for half an hour. Workers are paid $12 per hour each. Chemical’s purchase price is $500 per litre. Annual cost of capital is 5%. Other holding costs are estimated to be $0.5 per litre. Find the order quantity and the reorder point to satisfy a 95% service level during the lead time.

It costs Leaky Pipe $10 to process an order to replenish stock and $1 per unit per year to carry the item in stock. Stock is received 4 working days after an order is placed. No backordering is allowed. Assume 300 working days a year.a. What is Leaky Pipe’s optimal order quantity?b. What is the optimal number of orders per year?c.

- A firm experiences demand with a mean of 100 units per day. Lead time demand is normally distributed with mean 1000 units and standard deviation 200 units. It costs $6 to hold one unit for one year. If the firm wants to meet 90% of all demand on time, what is the expected annual cost of holding safety stock? Assume that each order costs $50.arrow_forwardSuppose the following item is being managed using a fixed-order quantity model with safety stock.

Demand is normally distributed with standard deviation of the monthly demand being 200 bags. The shop pays $12 for each bag to the supplier. The cost of ordering and receiving shipments is $12 per order. Accounting estimates annual inventory carrying cost is 30% of its value. The supplier lead time is a constant of 2 operating days. The shop operates 240 days per year, i.e., the shop operates 20 days each month. Each order is received from the supplier in a single delivery. The coffee shop uses continuous review (i.e., fixed-order quantity) inventory system and pays the supplier when the order is delivered (i.e., cash on delivery). There are no quantity discounts.
