A company would like to classify its inventory systems using ABC inventory classification system. The rules for ABC classification are STRICTLY applied such that 80% cumulative budget is assigned to A class Inventory items. The next 15% cumulative budget is assigned toB class inventory items, and Only 5% of the cumulative budget is assigned to C class inventory items. The inventory items are XYZ1, XYZ2,XYZ3, and XYZ4 respectively. The Annual demands (units per year) for these items are 290, 457, and 159, and 577 respectively. Also, the corresponding per unit prices are 19, 33, 126, and 90 respectively measured in OMR. Which items (among, XYZ1, XYZ2, XYZ3, and XYZ4) are classified as A class inventory O a. None is correct O b. Only XYZ3 O c. XYZ1only O d. BothXYZ3 and XYZ4 O e. All items

The principal goal of inventory management systems is to balance the costs of ordering, shipping, and receiving goods with the cost of carrying those goods, while simultaneously meeting the firm's policy with respect to avoiding running short of stock and disrupting production schedules. True False
What are the main advantages of implementing the Wilson approach in inventory management?
Hayes Electronics assumed with certainty that the ordering cost is $450 per order and the inventory carrying cost is $170 per unit per year. However, the inventory model parameters are frequently only estimates that are subject to some degree of uncertainty. Consider four cases of variation in the model parameters: (a) Both ordering cost and carrying cost are 10% less than originally estimated, (b) both ordering cost and carrying cost are 10% higher than originally estimated, (c) ordering cost is 10% higher and carrying cost is 10% lower than originally estimated, and (d) ordering cost is 10% lower and carrying cost is 10% higher than originally estimated. Determine the optimal order quantity and total inventory cost for each of the four cases. Prepare a table with values from all four cases and compare the sensitivity of the model solution to changes in parameter values.

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). Find dA>dq and d2A>dq2.
Your objective is to help company by determining EOQ* (Economic Order Quantity) that minimizes the totalinventory cost for a company that sells ceiling fans. Your worksheet provides information about the currentorder quantity, demand quantity and other costs.Questions: Answer A and Ba. With the current order quantity, what is the total cost of inventory?b. Implement the problem in Excel and find the order quantity (EOQ) (round to nearest integer) that givesminimum inventory cost. Note: this is a Non-linear programming, hence select “GRG Nonlinear” method inSolver- How much money would company save by switching to optimum quantity from current orderquantity?
I need a detailed explanation on how to solve this problem: A paint shop implements an inventory policy on its stock of white paint, which costs the store $6 per can. Monthly demand for cans of white paint is normal with mean 28 and standard deviation 8. The replenishment lead time is 14 weeks. Excess demand is backordered, but costs $10 per back ordered can in labor and loss of goodwill. There is a fixed cost of $15 per order, and the holding cost is based on 30% interest rate per annum. In your computations, assume 4 weeks per month. - Write down the model name and parameters. - What are the optimal lot size and reorder points for white paint (include the formulas)? - What is the optimal safety stock (include the formula)? *** Suppose the paint shop from the above problem adopts a service level policy. - What are the optimal lot size and reorder points for white paint, such that 90% of the cycles are filled without backordering (include all formulas)? - What is the fill rate…
Assume that JAO, Inc., a manufacturer of electronic test equipment, uses 14,400 units of an item annually. Its order cost is P500 per order, and the carrying cost is P10 per unit per year. It requires 10 days to place and receive an order. 1. The ordering costs is 5,696 4,026 6,000 4,8002. The inventory costs is 6,000 12,000 9,600 8,052
