An interactive computer program designed to facilitate the quantification of a decision maker's preferences for multiple objectives in terms of a multiattribute utility function is described. It is meant to alleviate many of the operational difficulties with current procedures for assessing and using multiattribute utility functions. The package includes commands for structuring the utility function, assessing single-attribute component utility functions of the overall multiattribute utility function, identifying the preference trade-offs between attributes, evaluating alternatives, and performing sensitivity analysis. Suggestions for using the program are included
