# 2 explain the differences between decision making under certainty uncertainty and risk

If, however, two projects or alternatives have significantly different expected monetary values, we can use standard deviation to measure relative risk of the two projects.

Types of Decision Strategic Decision: The decision-maker would thus choose to order units because this offers the maximum possible payoff. With the priori method, the decision-maker is able to derive probability estimates without carrying out any real world experiment or analysis.

Weather and climate affect nearly all segments of society, and there is a multitude of weather- and climate-related decisions and decision makers.

Risk can be measured and quantified, through theoretical models. It is worthwhile for Mr.

The distinction is drawn on the basis of the degree of knowledge or information possessed by the decision-maker. Each of the possible states of nature of the problems causes the manager himself can not predict with confidence what the outcomes of his action to be.

The decision to restock food supply, for example, when the goods in stock fall below a determined level is a decision-making under circumstance of certainty.

A will maximise this and choose A2. Using the formula of weighted average The weighted average hourly salary of the project would be One method to handle decisions under certainty with multiple criterion is the weighted sum method. These not only constitute a formal description of the problem but also provide the structure necessary for a solution: All we have to do is to subtract each entry in the payoff matrix from the largest entry in its column.

The Hurwicz alpha criterion seeks to achieve a pragmatic compromise between the two extreme criteria presented above. Here, for the sake of simplicity, we consider only two probability distributions.

Such a risk may include the probability of losing the part or whole investment. Y will pay Mr. In the environment of uncertainty, more than one type of event can take place and the decision maker is completely in dark regarding the event that is likely to take place.

If you pick a red marble, you win a prize. While the psychological perspective suggests that the statistical decision theory does not fully describe real-world decision making, such a process may aid decisions and improve understanding of decision making by reducing complexity and focusing the analysis.

Since profit is a random variable, the concept of maximum profit becomes meaningless. These probability assignments can then be utilized to calculate the expected payoff for each action and to choose that action with the maximum smallest expected payoff loss.

For example what is the relative importance between a set of attributes. There are two ways of adjusting the model in the light of reality, i.

Its major defect is that, as one number, the discount rate is used to combine the effects of both risk and the time value of money. The psychological factors in interpretation and use of uncertainty information apply mostly to individual end users.Managerial Decision-Making Under Risk and Uncertainty.

Article Shared by. ADVERTISEMENTS: Regret is defined as the difference between the ac­tual payoff and the expected pay-off, i.e., the pay­off that would have been received if the decision maker had known what event was going to occur. Decision-Making Environment under Certainty.

Operations Management Chapter 5S study guide by ch includes 43 questions covering vocabulary, terms and more. The difference between the expected payoff under certainty and the expected payoff under risk. Expected value of perfect information formula.

Expected payoff under certainty minus expected payoff under risk. Decision making. Decision Making under Certainty: The decision maker knows with certainty the consequences of every alternative or decision choice. E.g., LPP,TP,AP 2.

Decision Making under Uncertainty: Decision maker has no information at all about various outcomes or states of nature, i.e., the decision-maker does not know the probabilities of the various. Formal models of decision making under risk and uncertainty (such as statistical decision theory, discussed in Section ) have predominantly focused on analytic decision making, even though researchers have long been aware that abstract statistical evidence is typically at a disadvantage when people have a choice between it and concrete personal experience.

The basic differences between decision-making models under certainty, risk, and uncertainty depend on the amount of chance or risk that is involved in the decision. A decision-making model under certainty assumes that we know with complete confidence the future outcomes.
