Summary Introduction
To determine: The machine that should be recommended by TS person using the present value method.
Introduction:
Present value (PV):
It is the value that is in present form of money in contrast to some future amount. This is achieved when it is invested in compound interest.
The NPV is the measurement of profit that is calculated by subtracting the present values of

1. Decision Rules.
A company is choosing a motorized mechanism for a new toy, a dancing ballerina
(TippiToes) that is currently under development. Demand is uncertain. but the
company is confident that demand will be: Light (25,000 units), Moderate (100,000
units) or Heavy (150,000) units.
The payoff table for each mechanism (in $) is given below.
Action: Choice of Mechanism
Event
Gears and Levers
Spring
Weights and Pulleys
Pneumatic

400,000
300,000
Heavy
650,000
740,000
750,000
700,000
Questions:
(1) Apply Maximax, Maximin, Minimax Regret, and EMV rules (assuming that the
probability of Light demand is 0.1, Moderate demand is 0.7, and Heavy
demand is 0.2) to decide what mechanism should the company choose?
(2) What is the expected value of perfect information?
(3) Draw a decision tree to solve this problem.
A manager is trying to decide whether to buy one machine ortwo. If only one machine is purchased and demand provesto be excessive, the second machine can be purchased later.Some sales would be lost, however, because the lead timefor delivery of this type of machine is 6 months. In addition,the cost per machine will be lower if both machines are pur-chased at the same time. The probability of low demand isestimated to be 0.30 and that of high demand to be 0.70. Theafter-tax NPV of the benefits from purchasing two machinestogether is $90,000 if demand is low and $170,000 if demandis high.If one machine is purchased and demand is low, the NPV is$120,000. If demand is high, the manager has three options:(1) doing nothing, which has an NPV of $120,000; (2) subcon-tracting, with an NPV of $140,000; and (3) buying the secondmachine, with an NPV of $130,000.a. Draw a decision tree for this problem.b. What is the best decision and what is its expected payoff?

The hospital, however, must complete its first 10 transplants under great scrutiny and at no cost to the patients with the hospital picking the expenses. The cost per hour of surgery is estimated to be $5,000. The very first transplant, just completed, required 27 hours. On the basis of research at the hospital, Beth Zion estimates that it will have an 75% learning curve. Using Table E.3, estimate the time it will take to complete: a) the 10th transplant hours (round your response to two decimal places).

Last year’s records can provide a fairly good estimate of the parameters for this year. Wende Brown, the owner, does not believe things have changed much, but she did invest an additional $3,000 for modifications to the bakery’s ovens to make them more energy efficient. The modifications were supposed to make the ovens at least 15% more efficient. Brown has asked you to check the energy savings of the new ovens and also to look over other measures of the bakery’s productivity to see if the modifications were beneficial.

- Cox Electric makes electronic components and has estimated the following for a new design of one of its products. . Fixed cost-$21,000 • Material cost per unit $0.17 Labor cost per unit = $0.11 Revenue per unit $0.68 Note that fixed cost is incurred regardless of the amount produced. Per-unit material and labor cost together make up the variable cost per unit. Assuming that Cox Electric sells all that it produces, profit is calculated by subtracting the fixed cost and total variable cost from total revenue. Construct an appropriate spreadsheet model to find the profit based on a given production level and use the spreadsheet model to answer these questions. (a) Construct a one-way data table with production volume as the column input and profit as the output. Breakeven occurs when profit goes from a negative to a positive value; that is, breakeven is when total revenue the total cost, yielding a profit of zero.
