A fault diagnosis system which detects possible faulty components in a complex system. The complex system is represented by a representation comprising a plurality of nodes interconnected by links defining a flow among nodes corresponding to flows in the complex system. At least one of the nodes is a checkpoint node, which generates a report if the flow received by it is not correct. A fault diagnosis processor performing upstream search operation to repeatedly (such as by recursion of iteration) step in upstream path, that is, opposite to the direction of flow in the complex system, from node to node starting with the reporting checkpoint node. At each step, the fault diagnosis processor indicts components represented by both nodes and links in the representation.
