The maintenance department in Ranchi Hospital uses 816 cases of liquid cleanser annually. Ordering costs are $12, carrying costs are $4 per case a year, and the new price schedule indicates that orders of less than 50 cases will cost $20 per case, 50 to 79 cases will cost $18 per case, 80 to 99 cases will cost $17 per case, and larger orders will cost $16 per case. Determine the optimal order quantity and the total cost.
The Economic Order Quantity (EOQ) model is a classical model used for controlling inventory and satisfying demand. Costs included in the model are holding cost per unit, ordering cost and the cost of goods ordered. The assumptions for that model are that only a single item is considered, that the entire quantity ordered arrives at one time, that the demand for the item is constant over time, and that no shortages are allowed.
Suppose we relax the first assumption and allow for multiple items that are independent except for a restriction on the amount of space available to store the products. The following model describes this situation:
Let Dj =
annual demand for item j
Cj =
unit cost of item j
Sj =
cost per order placed for item j
i =
inventory carrying charge as a percentage of the cost per unit
W =
the maximum amount of space available for all goods
wj =
space required for item j
The decision variables are Qj, the amount of item j to order. The model is:…

- In Lecture 5 we extended the newsvendor solution to the infinite horizon problem when there is no order lead time. Now suppose that the order lead time is L periods throughout the infinite horizon: if an order is placed at the beginning of period t, it arrives at the beginning of period t+L. Can we still extend the newsvendor solution to the infinite horizon problem in the case of backordering? Why or why not? Would your answer change in the case of lost sales? Why or why or not?

The DC uses a reorder point (R) of 300 sets and afixed order quantity (Q) of 250 sets. The current on-hand inventory (OH) at the end of Day 1 is 400 sets, there are no scheduled receipts (SR), and there are no backorders (BO). Assume that all demands and receipts occur at the end of the day. The inventory position is compared to the reorder point after demands and receipts are accounted for. If necessary, an order is placed and the inventory position is updated. Given the demand schedule in the table below, determine when to order using a (Q) systemarrow_forward

- The Hawkins Supply Company is currently faced with an inventory rotation problem. This difficulty stems from the fact that some supplies must be used prior to a stated expiration date. Upon receipt, a new shipment of these perishable items must be stacked beneath the boxes that are currently in inventory. A substantial amount of time is consumed in restacking the items according to their expiration dates.The company would like to reduce the double and sometimes triple handling of items. How can this goal be achieved? Are there alternative solutions which might also be effective?arrow_forwardAuria will produce 3 vehicle components and knows that each start generates a cost of 5,000 pesos. The cost of the units is $ 200, $ 100 and $ 70 respectively. Annual demand is 100,000 units for Product A, 150,000 units for Product B, and 200,000 units for Product C. The inventory rate is 15% per month. Product A and B are basic and substitutable products, so there must be a minimum average inventory of 8,000 units of both. The company seeks a maximum of $ 100,000 invested money in inventory. The available warehouse space is 400m3 and product A occupies 0.5m3, product B 0.7m3 and C 1m3. Consider that product A and C allow shortages and the goodwill loss cost is $ 3 for each unit of those items. a) Formulate the problem as a mathematical programming model (objective function and constraints) that minimizes the total annual costarrow_forwardRecently, a kiddie store has been given a quantity discount schedule for these cats.

Furthermore, ordering cost is P1,960.00 per order. Annual demand is 5,000 toy cars, and inventory carrying charge, as a percentage of cost, I, is 20%.
