Concept explainers
a)
To draw: A decision tree for the given problem.
Introduction:
Decision tree is one of the methods used in decision-making process. It would graphically represent the available alternatives and states of nature. It would also mention the payoffs and probabilities of the alternatives. It helps to choose the best alternative that would give the best result among the alternatives.
b)
To determine: Maximin alternatives
Introduction:
Maximin is the decision making method which is used to make decision under uncertainty. This method will find an alternative that maximizes the minimum outcome of every alternative or we can say that calculating the minimum outcome within the each alternative.
c)
To determine: Expected value of perfect information (EVPI) and interpret it.
Expected value of perfect information: It is the rate that a person is willing to pay to gain access to perfect information. A common area which uses expected value of perfect information is the healthcare economy. This value tries to evaluate the expected cost of the uncertainty, which can be interpreted as the expected value of perfect information
The expected value of perfect information can be calculated by using below given formula:
d)
To determine: The sensitive analysis on P (high).
Introduction
Decision table is formats or visual representations were data is expressed arranged, determined and calculated to make a effective decision making. A decision table is a tabular representation that is used to analyze decision alternatives and states of nature.

- 1. A builder has located a piece of property that she would like to buy and eventually build on. The land is currently zoned for four homes per acre, but she is planning to request new zoning. What she builds depends on approval of zoning requests and your analysis of this problem to advise her. With her input and your help, the decision process has been reduced to the following costs, alternatives, and probabilities: Cost of land: $2 million. Probability of rezoning: 0.60. If the land is rezoned, there will be additional costs for new roads, lighting, and so on of $1 million. If the land is rezoned, the contractor must decide whether to build a shopping center or 1,500 apartments that the tentative plan shows would be possible. If she builds a shopping center, there is a 70 percent chance that she can sell the shopping center to a large department store chain for $4 million over her construction cost, which excludes the land; and there is a 30 percent chance that she can sell it to an…arrow_forwardAdam has been offered to open up a Service station. However, the size of the establishment will be based on his decision. The annual return and investment required will be based on both size and market condition.

Th e decision is whether to expand nowwith a large facility or expand small with the possibility of havingto expand again in fi ve years.Th e owners have estimated the following chances for demand:• Th e likelihood of demand being high is 0.70.• Th e likelihood of demand being low is 0.30.Profi ts for each alternative have been estimated as follows:• Large expansion has an estimated profi tability of either$80,000 or $50,000, depending on whether demand turnsout to be high or low.• Small expansion has a profi tability of $40,000, assumingdemand is low.• Small expansion with an occurrence of high demand wouldrequire considering whether to expand further. If the bakeryexpands at this point, the profi tability is to be $50,000.(a) Draw a decision tree showing the decisions, chanceevents, and their probabilities, as well as the profi tabilityof…arrow_forward
- A firm is weighing three capacity alternatives: small, medium, and large job shop.Whatever capacity choice is made, the market for the firm’s product can be “moderate”or “strong.” The probability of moderate acceptance is estimated to be 40%; strongacceptance has a probability of 60%. The payoffs are as follows. Small job shop,moderate market = $24,000; Small job shop, strong market = $54,000. Medium job shop,moderate market = $20,000; medium job shop, strong market = $64,000.Large job shop,moderate market = -$2,000; large job shop, strong market = $96,000.

- A retailer is deciding how many units of a certain product to stock. The historical probability distribution of sales for this product is 0 units, 0.2; 1 unit, 0.3; 2 units, 0.4, and 3 units, 0.1. The product costs $11 per unit and sells for $25 per unit.

The company is currently considering two options. The first is a small facility that it could build at a cost of $7.2 million. If demand for new products is low, the company expects to receive $10 million in discounted revenues (present value of future revenues) with the small facility. On the other hand, if demand is high, it expects $12 million in discounted revenues using the small facility. The second option is to build a large factory at a cost of $8 million. Were demand to be low, the company would expect $10 million in discounted revenues with the large plant. If demand is high, the company estimates that the discounted revenues would be $14 million. In either case, the probability of demand being high is .45, and the probability of it being low is .55. Not constructing a new factory would result in no additional revenue being…arrow_forward
