This paper describes a study on an integration of product modeling activity and reliability analysis activity. In order to support designer from the view point of reliability, it is necessary that the product modeling activity and reliability analysis activity are processed concurrently and the results of reliability analysis are presented to the designer during the modeling activity. To achieve the concurrent processing, the authors present a concept and a method of real time fault simulation that examines how the faults affect the design object during the modeling activity. In this concept, the fault simulation is decomposed into the solving operations of sub-problems and the coordinating operation of the solutions of the sub-problems, and these operations are performed during the modeling activity. A real time fault simulator is developed, which is integrated with a CAD system. An example is given to demonstrate the effectiveness of the method. It is found that the designers can obtain the information concerned with the fault propagation during the modeling activity by using the system.
