Decision making supported by fuzzy deontological statements

An approach to computer-assistant decision making problem is presented in the paper. The recommendations of actions that can be undertaken by an user in order to reach a desired goal are presented in the form of deontological statements. The necessary domain knowledge is provided to the system in the form of a domain ontology. The recommended actions are relatively evaluated by a system of semi-ordering relations suggested by the user. The semi-ordering relations constitute partial selection criteria of qualitative and/or quantitative type. Final solution is based on examination of an evaluation matrix. The method is illustrated by examples.
