A company purchases wood for use in its products. The firm uses 760 pounds of wood per week andpurchases wood for $1.75 per pound from a supplier. Each time the firm orders wood from the supplier,the firm must pay a $75 order processing charge. The firm's annual holding cost percentage is 31%.Do not round intermediate calculations. Assume there are 52 weeks in a year and roundyour answer to two decimal places.If the company orders 3,000 pounds of wood with each order, what is the sum of theannual holding and ordering costs?dollars

Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.
A hospital orders its thermometers from a hospitalsupply firm. The cost per thermometer depends on the ordersize q, as shown in Table 6. The annual holding cost is 25%of the purchasing cost. Let EOQ80 be the EOQ if the costper thermometer is 80¢, and let EOQ79 be the EOQ if thecost per thermometer is 79¢.a Explain why EOQ79 will be larger than EOQ80. b Explain why the optimal order quantity must be ei-ther EOQ79, EOQ80, or 100. c If EOQ80 100, show that the optimal order quan-tity must be EOQ79. d If EOQ80 100 and EOQ79 100, show that theoptimal order quantity must be either EOQ80 or 100.e If EOQ80 100 and EOQ79 100, show that the optimal order quantity must be EOQ79.
A firm uses the order-up-to model to manage its inventory. It wants to increase its in-stockprobability while decreasing its holding costs (i.e., reducing its average inventory). Which ofthe following actions will help to achieve this goal? (Consider each action independently.)I. Decrease the lead time.II. Increase the order-up-to level.III. Increase the average quantity on order.a. Only Ib. Only IIc. Only IIId. I and IIe. I and IIIf. II and IIIg. Any of them will help (that is I, II, or III).h. None of them will help.
The home appliance department of a large department store is using inventory models to controlthe replenishment of a particular model of Microwave ovens. The daily demand follows anormal distribution with a mean of 150 units and standard deviation of 16 units. The store pays$100 for each oven. Fixed costs of replenishment are $28. The accounting departmentrecommends a 20% annual holding cost rate. Assume that the average lead time is 5 days with astandard deviation of 1 day. Assume 365 days a year.Part A: What is the EOQ?Part B: What is the reorder point if the maximum chance of 5% of stock out (i.e. 95% servicelevel) is desired?Part C: What is the reorder point if a fill rate of 99% is required?Part D: Suppose management wants to simplify the process by setting the reorder point to“1000” units. Based on this policy, what is the implied chance of stock out?
Parasol Systems sells motherboards for personal computers. For quantities upthrough 25, the firm charges $350 per board; for quantities between 26 and 50,it charges $315 for each board purchased beyond 25; and it charges $285 eachfor the additional quantities over 50. A large communications firm expects torequire these motherboards for the next 10 years at a rate of at least 140 peryear. Order setup costs are $30 and holding costs are based on an 18 percentannual interest rate. What should be the size of the standing order?
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.
The lead time demand for bathing suits is governed bythe discrete random variable shown in Table 11. Thecompany sells an average of 10,400 suits per year.

ABC firm uses roughly 3,400 pounds of chemical dye a year. Currently, the firm purchases 300 pounds per order and pays P120.00 per pound. The supplier has just announced that orders of 1,000 pounds or more will be filled at a price of P80.00 per pound. The manufacturing firm incurs a cost of P4,000.00 each time it submits an order and assigns an annual holding cost of 17% of the purchase price per pound. a. Determine the order size that will minimize the total cost.b. If the supplier offered the discount at 1,500 pounds instead of 1,000 pounds, what order size would minimize total cost?
Rocky Mountain Tire Centre sells 20,000 tires of a particular type per year. The ordering cost for each order is $40, and the holding cost is 20% of the purchase price of the tires per year. The purchase price is $20. per tire if fewer than 500 tires are ordered, $18. Per tire if more than 500 but fewer than 1,000 tires are ordered and $17. per tire if 1,000 or more tires are ordered. Quantity Unit Price 1-499 $20. 500-999 $18. 1000 & over $17 Based on available information, lead time demand for CD-ROM drives averages 50 units (normally distributed), with a standard deviation of 5 drives. Management wants a 97% service level. What value of Z should be applied? How many drives should be carried as safety stock?
I need a detailed assistance to solve this problem in: Operations Analysis. 3) A chemical manufacturer produces a compound at the rate of 10,000 pounds a day over 250 days each year. Annual demand for that compound is 600,000 pounds per year, and each pound sells for $3.90. There is a fixed setup cost of $1,500 for each production run, and a variable cost of $3.50 for each pound produced. The following costs are incurred: Interest rate on the cost of capital is 22% per annum (annually). Storage and handling costs amount to 12% of the compounds cost per annum. a)- What is the optimal production lot for the compound (write down the model name, its parameters and formula)? b)- Compute the uptime, downtime and cycle time in days, and find the cycle fraction of uptime and the cycle fraction of downtime (include the formula). c)- What are average annual holding and setup costs for the compound (include the formula)? d) - What is the annual profit for this compound?
