Consistency in fuzzy rule based systems: an application inelementary school performance evaluation

摘要

Performance evaluation and reform of public organizations isreceiving increased attention. In many cases identification of thelowest performing organizations is an important part of performancebased reforms. Programs to identify low performance would typicallybenefit from incorporation of expert judgement, provided that judgementcould be applied in a verifiable and fair manner. Fuzzy rule basedsystems provide a mechanism for modeling expert judgement. However,translating that expertise into a consistent set of rules can be evenmore challenging for performance evaluation than it has been inengineering applications. We describe an approach that first creates acomprehensive and complete set of rules and then modifies those rules toprevent inconsistent results
