This work describes an integration of an entity/relationship model and fuzzy databases. It outlines a formal model for representing fuzziness in the ER model, and sketchs a version of the ER algebra, adapted to manipulating fuzzy databases.

This work is concerned with the initial design of an expert system for increasing utilization of evaluations in the social sciences. It is an empiric fact that evaluation findings in the social science have a very low and unpredictable utilization. An expert System for Utilization of Research (SUR) may serve both as a research tool (expert systems research and utilization research) and later as an aid to evaluators in the field. The system will be used to collect and store existing utilization research expertise, sort it and detect contradictions. A dynamic model of interaction of an evaluator and an organization will be developed, and the system will be used to simulate interactions and devise strategies and responses applicable to different scenarios. The system may also be used by the applied evaluator as a sophisticated tool for presentation of recommendations, and as a supportive guide for conducting good evaluations.
