Decision strategy | Short description |
---|---|
Weighted addititive (WADD) | Taking into account the values of each alternative on all relevant attributes; considering the relative importance of each attribute; multipying weights times attribute values; summing weighted attribute values over all attributes. |
Additive difference (ADDIF) | Comparing pairs of alternatives directly on each dimension; determining the differences between subjective values of alternatives on a particular dimension; applying weighting function to each difference and summing results over all dimensions to obtain overall relative evaluation of two alternatives. |
Equal weight (EQW) | Choosing on basis of the sum of all values; ignoring information about relative importance. |
Elimination-by-aspects (EBA) | Assessing most important attribute; eliminating all options that are not satisfactory with respect to that attribute; repeating for next most important attribute and so on, until there is one option left. |
Satisfying (SAT) | Choosing the first option that is satisfactory. |
Lexicographic (LEX) | Assessing most important attribute; selecting the option that has the best value on that attribute. |
Lexicographic semiorder (LEXSEMI) | Assessing most important attribute; selecting the option that has the best value on that attribute; including notion of selecting alternatives that are within just-noticeable difference (JND) of the best alternative. |
Majority of confirming dimensions (MCD) | Choosing by comparing pairs of alternatives; winner is compared with the next alternative in the set; simplified version of the ADDIF strategy (only direction of differences is considered, not the magnitude). |
Frequency knowlegde (FRQ) | Counting the number of good and bad features; the option with the smallest numer of bad features or the option with the biggest number of good features is chosen. |
Habitual heuristic | Choosing what you chose last time. |
Affect referral | Recalling from memory previously formed evaluations for familiar alternatives; choosing acoordingly. |
Price-oriented | Buying the cheapest product. |
In store | Buying the first product you find. |
