We note that a nearer to unity indicates that the decision-maker is optimistic while a value nearer to zero indicates that he is pessimistic. Sometimes we make decisions using information involving uncertainty, such as future weather conditions. These types of decisions are called decisions under certainty. The monetary payoffs of each combination of Ai and Sj are given in the following table: Solution: Since 17 is maximum out of the minimum payoffs, the optimal action is A2. Conditions of uncertainty exist when the future environment is unpredictable and everything is in a state of flux. Then the regret in selecting Ai, to be denoted by Rij is given by X2j - Xij, i = 1 to m. We note that the regret in selecting A2 is zero.
