certainty and uncertainty in decision analysis

Decision making is a process of identifying problems and opportunities and choosing the best option among alternative courses of action for resolving them successfully. In the analysis of decision making, three types of knowledge with respect to outcomes are usually distinguished: Certainty: Complete and accurate knowledge of outcome of each alternative. Under conditions of certainty, accurate, measurable, and reliable information on which to base decisions is available. it is to reduce uncertainty. In terms of the payoff matrix, if the decision-maker selects A 1, his payoff can be X 11, X 12, X 13, etc., depending upon which state of nature S 1, S 2, S 3, etc., is going to occur. There is only one outcome for each alternative. 2. decision making under certainty, risk & uncertainty Explain the difference between decision-making under certainty, risk and uncertainty. ... get quotes, etc. The extent to which an uncertainty analysis can be considered “fit for purpose” in part depends on the decision(s) the modeling seeks to support. When such conditions of uncertainty is there then to make decision, a businessman or manager has two alternatives. Uncertainty is a lack of complete certainty. A situation of uncertainty arises when there can be more than one possible consequences of selecting any course of action. The construction and use of scenarios in decision analysis is reviewed in Sections 6 Decision analysis based on scenarios, 7.4 Scenarios. Decision analysis is a process that allows the decision maker to select at least and at most one option from a set of possible decision alternatives. Uncertainty analysis can serve two main pur-poses: assess confidence in a chosen course of action and ascer-tain the value of collecting additional information to better inform the decision. Describe the decision-making environments of certainty and uncertainty. Decision-making under Certainty A condition of certainty exists when the decision-maker knows with reasonable certainty what the alternatives are, what conditions are associated with each alternative, and the outcome of each alternative. He is also the co-author, along with John Kay, of Radical Uncertainty: Decision-Making beyond the Numbers. What follows is a lightly edited transcript of our … There must be uncertainty regarding the future along with the objective of optimizing the resulting payoff (return) in terms of some numerical decision criterion.
