Tools for Decision Making under Uncertainty V. Seˇck´arov´a Charles University, Faculty of Mathematics and Physics, Prague, Czech Republic. Decision Making Under Certainty Uncertainty and Risk Examples. Sometimes we make decisions using information involving uncertainty, such as future weather conditions. realms of decision-making under either: (a) Certainty, where each action is known to lead invariably to a specific outcome. Under conditions of certainty, accurate, measurable, and reliable information on which to base decisions is available. For example, if an investor has $1000, he can invest it at 6% in a bank and be certain that the return will be $60 in one year. He has received an order which can processed either Normative theories focus on how to make the best decisions by deriving algebraic representations of preference from idealized behavioral axioms. Example project for a really simple implementation of the AHP - Analytic Hierarchy Process topic mentioned in the book "Operations Research: An Introduction, Hamdy A. Taha". However, the decision making environment is also an important factor of the process. When a Risk-Averse decision-maker acts, a risky opportunity would be exchanged for one that has a definite outcome. Decision making under certainty In this environment, the payoffs for various criteria are known and guaranteed. Decision-making is needed whenever an individual or an organization (private or public) is faced with a situation of selecting an optimal (or best in view of certain objectives) course of action from among several available alternatives. 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. (2) Risk A state of risk exists when the manager is aware of all the alternatives, but is unaware of their consequences. Decision Analysis. DECISION MAKING UNDER CERTAINTY In this decision making environment, decision maker has complete knowledge (perfect information) of outcome due to each decision alternative (course of action).

Decision making is a process used in many parts of life to determine an optimal choice with respect to a particular subjective aim for a particular decision maker. These problems range from making decisions in which information about the parameters of the problem are known with certainty, unknown, or determined probabilistically.
