Thermtech Science has performed an economic analysis of proposed service in a new region of the country. The three-estimate approach to sensitivity analysis has been applied. The optimistic and pessimistic values each have an estimated 15% chance of occurring. Use the FW values shown to determine the expected FW. Optimistic Most Likely Pessimistic FW value, $ 200,000 40,000 −25,000
An industrial machine costing $10,000 will produce net cash
savings of $4,000 per year. The machine has a five-year useful life
but must be returned to the factory for major repairs after three
years of operation. These repairs cost $5,000. The company's
MARR is 10% per year. What IRR will be earned on the purchase
of this machine? Analyze the sensitivity of IRR to $2,000
changes in the repair cost.
Perform the sensitivity analysis. Fill-in the table below. (Round to

Each order costs £a to place, and the cost of holding stock is b% of the average value of stock per annum. Determine the optimal order quantity. A local firm uses 2000 units of a particular component each year. The component has a purchase price of £4/unit, while the cost of holding stock is estimated at 20% of the average stock value. If the cost of placing each order is £12.50, find the optimal number of orders placed each year. Suppose the component supplier offers a discount of 2% on the purchase price if orders are placed in units of 1000. Is the discount worth accepting? Suppose that instead of a single figure you had been given a probability distribution for the number of units used each year. Indicate the effect on stock policy..

- When the country’s economy is expanding, AB Investment Company is optimistic and expects a MARR of 15% on new investments. However, in a receding economy the expected return is 8%. Normally a 10% per year return is anticipated. An expanding economy causes the estimates of project life to go down about 20%, and a receding economy causes the life values to increase about 10%. Additionally, the market value after the project’s life varies widely; optimistically, it may be as high as 50% more or as low as 75% of the initial investment. (a) Summarize the optimistic, most likely, and pessimistic estimates in tabular form. (b) Use a spreadsheet to calculate and plot the sensitivity of PW versus (1) MARR, (2) life values, and (3) market value for possible investment in one of two locations. Use the most likely estimates for the other parameters. (c) Considering all the analyses, under which scenario, if any, should location Miami or Houston be rejected?
