1 Question 23A large producer of household products purchases a glyceride used in one of its deodorant soaps from outside of the company at a cost of$2.5 per pound. It uses the glyceride at a fairly steady rate of 40 pounds per month, and the company uses a 23 percent annual interestrate to compute holding costs. The chemical can be purchased from a supplier who charges a delivery fee that varies on the orderingquantity as follows:Order SizeDelivery FeeEOQ0

Cost per unit = $2.5 Monthly demand = 40 pounds Annual demand = 40*12=480 pounds Holding cost % =…

QUESTION 2a. A manufacturing company Glass Items Manufacturing Limited (GIM), operating under acontinuous review system, has an average demand of 150 units per week for the item it produces.The standard deviation in weekly demand is 30 units. The lead-time for the item is seven weeks,and it costs the company $70 to process each order. The holding cost for each unit is $30 per year.The company operates 52 weeks per year.A normal distribution table is appended to this assignment. (i) Use the information in 2 a. above.

QUESTION 1:A confectioner buys plastic boxes in bulk and uses them to pack chocolates. The annual requirement of these boxes is 1,200, and each box costs $30. The ordering and carrying costs are $10 per order and 20%, respectively. The supplier from whom the confectioner purchases these boxes sells them only in lots of 25, that is, you only purchase quantities in multiples of 25 boxes.(a) How many boxes should the confectioner order so as to minimise inventory total stocking costs?(b) If the supplier offers 2% discount on the cost of each box when the purchases are in quantities of 300 at a time, should the confectioner accept this offer?(c) Suppose the supplier has decided that instead of the 2% discount offer the following price breaks will be used:ORDER QUANTITY COST PER BOXLess than 100 $30.00100 to 199 $29.75200 or more $29.60What order quantity should the confectioner make?
Question 2: Metro Tech buys three components from a local wholesaler. The annual demand for components A, B, and C is 500, 3000, and 6000 units respectively. The agreed purchase price is $20, $15, and $10per unit for A, B, and C respectively for each product. The holding cost is estimated to be 20% per year. The ordering cost consists of handling and trucking costs. The handling cost is $100 for each type of component regardless of the number of items ordered. In addition to the handling cost, Metro Tech must pay a trucking cost of $500 for each delivery regardless of the total number of components in the order. Currently, all three items are being ordered independently using EOQ models. A proposal has been made to combine the ordering of the three items to save on trucking costs. Analyze the current and the prosed scenario and show the results below. Input Data: Demand items/year Item Cost in $/item Holding Cost as %/year Ordering Cost $/order # of Orders/ year Economic Order Quantity…
Problem 20-36 (Algo) Palin’s Muffler Shop has one standard muffler that fits a large variety of cars. The shop wishes to establish a periodic review system to manage inventory of this standard muffler. Use the information in the following table to determine the optimal inventory target level (or order-up-to level). Annual demand 3,910 mufflers Ordering cost $ 75 per order Standard deviation of daily demand 6 mufflers per working day Service probability 87 % Item cost $ 27.00 per muffler Lead time 2 working days Annual holding cost 36 % of item value Working days 230 per year Review period 18 working days a. What is the optimal target level (order-up-to level)? (Use Excel's NORMSINV() function to find the correct critical value for the given α-level. Do not round intermediate calculations.

Question 8 What of the following best describes just-in-time inventory management? A firm minimises the time lags present in the supply chain by maintaining a certain amount of inventory to use in these lag times Inventory is maintained as a buffer to meet uncertainties in demand, supply, and movements of goods Production inefficiencies arising when production capacity stands idle for lack of materials are minimised by holding a small stock of essentials at all times A firm acquires inventory precisely when needed so that its inventory balance is always at, or close to, zero
Question 1 (Stock Control) - : Suyuti Auto purchases a component used in the manufacture of automobile generators directly from the supplier. Suyuti's generator production operation, which is operated at a constant rate, will require 1000 components per month throughout the year (12 000 units annually). Assume that the ordering costs are GH¢25 per order, the unit cost is GH¢2.50 per component and annual holding costs are 20 per cent of the value of the inventory. Suyuti has 250 working days per year and a lead time of five days. Answer the following inventory policy questions. a. What is the EOQ for this component? b. What is the reorder point? c. What is the cycle time? d. What are the total annual holding and ordering costs associated with your recommended EOQ?
QUESTION 10 An automotive warehouse stocks a variety of parts that are sold at neighborhood stores One particular part, a popular brand of oil filter, is purchased by the warehouse for $1.50 each. It is estimated that the cost of order processing and receipt is $100 per order. The company uses an inventory carrying charge based on a 25 percent annual interest rate. The monthly demand for the filter follows a normal distribution with mean 280 and standard deviation 70. Order lead time is assumed to be five months. Assume that if a filter is demanded when the warehouse is out of stock, then the demand is back-ordered, and the cost assessed for each back-ordered demand is $12.80. Determine the optimal values of the order quantity and the reorder level Q= 1358 R= 1765
Practice Question: 1. A small local pharmacy, Tacky Pharm sells self-test kits for diabetic patients. These kits cost Tacky $15 each. Customers want to buy the kits at a rate of 240 per week. The pharmacy operates 52 weeks per year. Tacky Pharm estimates ordering cost at $50. Annual holding costs are 20 percent of the unit cost. Lead time is 2 weeks. Using the information given, (1) Calculate the economic order quantity. (2) Calculate the total annual costs using the EOQ. (3) Determine the reorder point.
Question 1 The Jelly Bean operation holds an inventory of food colouring which used to colour the jelly beans. The jelly bean operation is interested in calculating the optimal ordering strategy for food colouring. Suppose the annual forecast for the necessary food colouring during a normal year of operation is 13491 litres per year. Furthermore, suppose the holding cost per litre of paint is $11.4 and every time the jelly bean operation issues an order to their supplier, a charge of $451 is added to the invoice as an ordering cost. The supplier charges $5.63 per litre of food colouring. Using the Economic Order Quantity formula, what is the optimal order size that minimises total cost (in Litres of food colouring per order)? a. 1265 litres b. 736 litres c. 1067446 litres d. 26 litres e. 1033 litres Question 2 Using the Economic Order Quantity formula and the data provided above, how many orders will have to be made in a single year?
