| Tiivistelmä: | Total preferential independence is a necessary condition for the widely used additive value function. Cases when this substitutability is not present are considered, the value functions that are applicable to such cases are investigated. The case of total nonsubstitutability is studied, and it is proved that the maximum value function is appropriate for it. The result is extended to the closely related maximax value function. Next the case is considered when there is neither total substitutability nor total nonsubstitutability, and the application of a minsum value function is shown. A minsum function is one that uses only addition and minimum extraction operations. |
