Construction of Knowledge-based Simulation Environment Using Expert System and Database

As the application domains of rule-based systems become larger and more complicated, the integration of rule-based systems within the database systems has become the topic of many research works. This paper suggests a simulation modeling usmg expert system and database. The integration methods employed in this research are as follows. First, we defined new states and state transition functions to interrelate simulation model and expert system. Second, we designed and implemented FCLCFact Class Library) as a interface of expert system and database. FCL has facili es of filtering data from database, and assigning a meaning to the filtered data. Also, FCL detects the violation of the integrity rules in database, as the result of inference is reflected. Some implementation problems are pointed out and the methods to ve these problems are discussed in this paper. We developed a simulation model of the grating production line and executed it to validate the functions of the proposed method.
