This paper proposes an intervention support system between a manufacturing machine and a human for an anthropocentric factory automation system, which deals with feasible human interfaces and which treats unexpected problems in variable-kind variable-quantity production. In such production, repair tasks, dependent on non-deterministic human judgment, are required for raising the restorative capability of the system. An intervention support system using data carriers, engineering workstations, a point-of-production system, and PLC language is constructed. In this intervention support system, workers can understand the entire system, and heuristic information from tasks is easily accumulated as a result of experience at the shop-floor level.
