- 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.

- Forrest and Dan make boxes of chocolates for which the demand is uncertain. Forrest says, “That’s life.” On the other hand, Dan believes that some demand patterns exist that could be useful for planning the purchase of sugar, chocolate, and shrimp. Forrest insists on placing a surprise chocolatecovered shrimp in some boxes so that “You never know what you’ll get.” Quarterly demand (in boxes of chocolates) for the last 3 years follows: Quarter Year 1 Year 2 Year 3 1 2 3 4 3,000 1,700 900 4,400 3,300 2,100 1,500 5,100 3,502 2,448 1,768 5,882 Total 10,000 12,000 13,600 a. Use intuition and judgment to estimate quarterly demand for the fourth year.b. If the expected sales for chocolates are 14,800 cases for year 4, use the multiplicative seasonal method to prepare a forecast for each quarter of the year. Are any of the quarterly forecasts different from what you thought you would get in part (a)?arrow_forwardProduction Quantity Model A stew production facility sells the stew in an adjoining store. Demand for the stew is 32 gallons per day. Both the store and production facility operate 310 days per year. The company can produce 128 gallons per day. It costs $1200 to set up a production run. The stew is stored at an annual cost of $20 per gallon. The company wants to use the optimal order quantity. (Round the order quantity to an integer value) What is the maximum inventory level? How many production runs will be required each year? What is the total annual carrying cost? If the store places an order to the production facility for 1000 gallons of stew (not necessarily the economic order quantity), how many gallons of stew will be sold during the order receipt period?arrow_forwardd. The weekly average inventory listed above cannot change much since the grocery store is limited in storage capacity, and can therefore assumed to remain constant over time. The store has calculated that having less than 3 weeks of supply will create problems keeping stock available for clients. What annual cost of goods sold will bring about this condition (3 weeks of supply)?e. The grocery store is increasingly popular and management has calculated that, on average, the cost of goods sold increase by $5 million per year, reflecting better sales. How many years will it take for the grocery store to require expansion?arrow_forward
