An apparatus for testing operation of system components such as elevator cages under group-supervision control which has a central processor and stored control programs to provide group-supervision control of elevator cages including selecting cages from among a plurality of cages, on the basis of signals from hall call buttons for calling cages and destination call buttons, and causing the selected cages to travel to destination floors. The apparatus includes programs which produce diagnostic results and are incorporated with the stored control programs for controlling and operating the system. In one embodiment, the programs direct the cages to execute test operations which simulate normal operations of the cages under group-supervision control. In a second embodiment, the programs operate during normal cage operation. In both embodiments the programs provide a conservation function which selects and holds group-supervisory predictive-information values that are used in the group-supervision control programs, a group-supervisory information actual-measurement function which measures actual values which correspond to the predictive-information values, and a predictive-information accuracy function which compares the predictive-information values and the measured actual values and diagnoses the presence of an abnormality.
