The current solution to SureStep’s no-backlogging aggregate planning model requires a lot of firing. Run a one-way SolverTable with the firing cost as the input variable and the numbers fired as the outputs. Let the firing cost increase from its current value to double that value in increments of $400. Do high firing costs even- tually induce the company to fire fewer workers?

In the cash balance model from Example 11.5, the timing is such that some receipts are delayed by one or two months, and the payments for materials and labor must be made a month in advance. Change the model so that all receipts are received immediately, and payments made this month for materials and labor are 80% of sales this month (not next month). The period of interest is again January through June. Rerun the simulation, and comment on any differences between your outputs and those from the example.
A market analyst working for a small appliance manufacturer finds that if the firm produces and sells x blenders annually, a model for the total profit (in dollars) is P(x) = 8x + 0.3x2 − 0.001x3 − 372. Graph the function P in an appropriate viewing rectangle, and use the graph to answer the following questions. (a) When just a few blenders are manufactured, the firm loses money (profit is negative). (For example, P(10) = −263, so the firm loses $263.00 if it produces and sells only 10 blenders.) How many blenders must the firm produce to break even? (Round your answer to the nearest whole number.) blenders(b) Does profit increase indefinitely as more blenders are produced and sold? YesNo If not, what is the largest possible profit the firm could have? (If profit increases indefinitely, enter your answer as ∞. Otherwise, round your answer to the nearest cent.)
In the Walton Bookstore example with a discretedemand distribution, explain why an order quantityother than one of the possible demands cannot maximizethe expected profit. (Hint: Consider an orderof 190 calendars, for example. If this maximizesexpected profit, then it must yield a higher expectedprofit than an order of 150 or 100. But then an orderof 200 calendars must also yield a larger expectedprofit than 190 calendars. Why?)
Change the capital budgeting model in Figure 6.5 so that 80% of each cost in row 5 is incurred right now, at the beginning of year 1, and the other 20% is incurred a year from now, at the beginning of year 2. You can assume that the NPVs don’t change. The available budget in year 1 is $11.5 million, and the budget in year 2 is $3.5 million.a. Assuming that available money uninvested in year 1 cannot be used in year 2, what combination of investments maximizes NPV?b. Suppose that any uninvested money in year 1 is available for investment in year 2. Does your answer to part a change?
Your company orders packs of gums and, then, sells them to retailers. The profit you get from each pack is $5. The salvage loss is $3 for each pack, which is the amount you lose if you buy more than the demand. The following table shows the demand for the number of packs of gums over 300 days. For instance, you have 10 packs of gums demanded for 60 days (out of 300 days). Packs demanded 10 11 12 13 Number of days 60 90 120 30 Calculate your optimal order number for the packs of gums. What is the max amount to pay to know the certain demand?
The purchased and installation costs of some pieces of equipment are given as a function of weight rather than capacity. An example of this is the installed costs of large tanks. The 1980 cost for an installed aluminum tank weighing 100,000 lb was $390,000. For a size range from 200,000 to 1,000,000 lb, the installed cost-weight exponent for aluminum tanks is 0.93. If an aluminum tank weighing 700,000 lb is required, what is capital investment needed in 2002? Notice: If you can't find exponent (x), you can use the value 0.6
Company A's stock sells for $142 a share and has a 3-year average annual return of $27 per share. The beta value, a measure of risk, is 0.38. Company B sells for $149 a share and has a 3-year average annual return of $61 a share. The beta value is 1.23. Tori wants to spend no more than $12000 investing in these two stocks, but she wants to obtain at least $3000 in annual revenue. Tori also wants to minimize the risk, that is, the beta value. Determine how many shares of each stock Tori should buy.
Use excel for this problem A trust officer at the Blacksburg National Bank needs to determine how to invest $150,000 in the following collection of bonds to maximize the annual return. Bond Annual Return Maturity Risk Tax Free A 9.5% Long High Yes B 8.0% Short Low Yes C 9.0% Long Low No D 9.0% Long High Yes E 9.0% Short High No The officer wants to invest at least 40% of the money in short-term issues and no more than 20% in high-risk issues. At least 25% of the funds should go in tax-free investments, and at least 45% of the total annual return should be tax free. Formulate the LP model for this problem. Create the spreadsheet model and use Solver to solve the problem.
A firm is considering importing some products to sell in a local market. The unit price and cost for product i are p; and Cį, respectively. While the prices may be determined by the firm, the costs are given and fixed. For product i, the demand volume is Aį – Bipi, where A; and Bi are all given. The amount of budget that may be used to purchase all products is K. The demand volume may be fractional. Formulate a mathematical program that can find a purchasing plan that maximizes the firm's profit. Determine whether your program is an LP, IP, or NLP.
A local finance company quotes a 16 percent interest rate onone-year loans. So, if you borrow $26,000, the interest for the year will be $4,160. Because you must repay a total of $30,160 in one year, the finance company requiresyou to pay $30,160y12, or $2,513.33, per month over the next 12 months. Is this a15 percent loan? What rate would legally have to be quoted? What is the effectiveannual rate?
Dataware is trying to determine whether to give a $10 rebate, cut the price $6, or have no price change on a software product. Currently, 40,000 units of the product are sold each week for $45 apiece. The variable cost of the product is $5. The most likely case appears to be that a $10 rebate will increase sales 30%, and half of all people will claim the rebate. For the price cut, the most likely case is that sales will increase 20%.a. Given all other assumptions, what increase in sales from the rebate would make the rebate and price cut equally desirable?b. Dataware does not really know the increase in sales that will result from a rebate or price cut. However, the company is sure that the rebate will increase sales by between 15% and 40% and that the price cut will increase sales by between 10% and 30%. Perform a sensitivity analysis (two-way data table) that could be used to help determine Dataware’s best decision.
I own a single share of Wivco stock. I must sell myshare at the beginning of one of the next 30 days. Each day,the price of the stock changes. With probability q(x), theprice tomorrow will increase by x% over today’s stock price(x can be negative). For example, with probability q(5),tomorrow’s stock price will be 5% higher than today’s. Showhow dynamic programming can be used to determine astrategy that maximizes the expected revenue earned fromselling the share of Wivco stock. Assume that at thebeginning of the first day, the stock sells for $10 per share.
