Consultation systems based on goal-driven reasoning such as MYCIN, tend to impose redundant and tiresome interactions on the user. For practical use, it is necessary to realize flexible reasoning mechanisms and mixed-initiative interactions between the user and the system. This paper presents a fault diagnosis system with parallel reasoning and interaction. To realize a flexible reasoning, the following functions are necessary: (a) to run multiple goal-driven reasoning processes in parallel, (b) to control the reasoning processes dynamically in the user-initiative mode or the system-initiative one, (c) to monitor the degree of attainment of each diagnosis goal and the degree of contribution of each query for goal attainment and to use them in the reasoning control. Multiple queries are shown simultaneously in the query window. The user may select and answer only important queries ralated to his current focus. An application of this system against the operating system driving the rotary cutting machine has showed that the system is effective in supporting the diagnosis. The user can alter the diagnosis strategy voluntarily and dynamically according to the stage reached in the diagnosis session.
