AbstractThe derivation of weights from preference statements is subject to difficulties, some of which are due to the unreliability of the judgement of the decision maker. To overcome this Jaynes' principle of maximum entropy has been invoked and may be applied either to weights or to the linear weighted scores of the candidates in a selection problem. When candidates are relatively few the two strategies give different styles of interaction. These are discussed and illustrated by application to a problem of personnel selection.

Concepts involving entropy have intermittently been used in consideration of multiattribute problems. This paper discusses the main approaches that have been proposed. It is argued that the analogies drawn with information theory and between weights and probabilities are to some degree unsatisfactory and a reconsideration is given. The result is a new suggestion in the spirit of Jaynes’ maximum entropy methodology, but now in two parts: ask those questions that are likely to be most discriminating (minimize entropy) but process the answers obtained conservatively (maximize entropy). In contrast to many previous methods, it is the distribution of the utilities of alternatives rather than of the weights given to attributes that is the focus of attention.
