Which of the following statements is FALSE of a fixed-quantity system (FQS)?
Select one:
a.
In FQS, fixed quantity is ordered to bring the inventory position up to the replenishment level.
b.
In FQS with uncertain demand, the reorder point is chosen to include the demand during lead time, plus any safety stock.
c.
In FQS, inventory position is checked continuously, rather than at fixed intervals of time.
d.
In FQS, orders are placed when the inventory position reaches or drops below the reorder point.
e.
In FQS with uncertain demand, orders are placed with the same order quantity, but not necessarily with the same periodicity.
The basic EOQ model is based on all the following assumptions except: *
A. Annual demand is known and constant.B. The item is always available when needed.C.Estimates of ordering and carrying costs are accurate.D.Order is instantaneously received exactly when previous inventory has just been used up.
Which of the following is NOT an assumption of the EOQ model?a. It is possible to receive a purchase discount if the order quantity is sufficiently large.b. There is a fixed cost to submit each order that is independent of the amount ordered.c. Demand occurs at a constant rate per unit of time.d. There is a cost to hold each unit of inventory per unit of time

- 1- The number of orders in the inventory system (called A) is total demand (called D) divided D by order size per replenishment (called S) or A =". D follows a normal distribution with a mean of 100,000 and standard deviation of 5000. While S is a continuous uniform distribution between 20,000 and 30,000. Generate 500 A random number and find the average.arrow_forwardYou are conducting a retrospective analysis for an Order-Up-To system (thus, the unsold inventory at the end of a week is carried over to the next week). The beginning inventory in week 1 is 150 units, the demand in week 1 is 180 units and the demand during week 2 is 250 units. If you receive a shipment of 115 units every week, at the end of week 2, the inventory level is 180 the inventory level is 200 the inventory level is 310 the backorder level is 30 the backorder level is 50 none of the above is correctarrow_forwardAssuming constant annual demand for an item, increasing its orderquantity: A. Increases the number of orders placed per year.B. Increases the total annual purchasing cost.C. Increases the total annual inventory carrying costs.D. Decreases the number of orders placed per yeararrow_forward

They order a week with one week lead time. Backorders are allowed. A) With an order-up-to level of 300, on-hand inventory of 200, and on-order inventory of 60, how much will be ordered this week? B) What is the standard deviation of demand over 2 weeks?arrow_forward
- The level of inventory at which a new order needs to be placed to replenishdepleted stock is called the: A. Service level.B. Reorder point.C. Minimum inventory level.D. Safety stock.arrow_forwardA company has the demand of 1800 units per year (demand rate is constant), holding costs of $13 per unit and setup costs (ordering cost) of $27 per order. The order lead time is 1 days, and the company operates 245 days every year. To avoid a stockout, they need to place an order at least ______ days before the inventory runs out.arrow_forwardA 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?arrow_forward
- 12 Which of the following is NOT an assumption of the economic order quantity model shown below? Select one: a. Demand is known, constant, and independent. b. Lead time is known and constant. c. Production and use can occur simultaneously. d. The only variable costs are setup cost and holding (or carrying) cost. e. Quantity discounts are not possible.arrow_forwardSuppose the newsvendor model is used to manage inventory. Which of the followingcan happen when the order quantity is increased by one unit? a. Expected sales increases by more than one unit.b. Expected leftover inventory increases by more than one unit.c. Expected sales decrease by less than one unit.d. Expected leftover inventory increases by less than one unit.arrow_forwardDemand 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.arrow_forward
