This case study examines the design and development of an expert system used to fairly distribute the opportunity to earn overtime pay among workers in a manufacturing environment. It describes the problem and the mechanisms used to prioritize workers for selection and details some of the difficulties encountered in the knowledge engineering stage. The benefits derived by using the system are given, as are some of the lessons learned during the development and deployment.
