Methods for operating a management system that manages a large number of first function modules and second function modules. An inhibitor module I sets first control statuses to designating blocking when associated events are detected by an event detecting device, and then the management system no longer makes associated first function modules available for execution. The inhibitor module I sets second control statuses to designating executable when associated events are detected by an event detecting device, and then the management system makes associated second function modules available for execution.
