Abstract:
A novel
method of diagnosability analysis of manu- facturing systems is
presented and the necessity and sufficient condition of fault
diagnosability of manufacturing systems is derived on the basis of
developing state space model of a manufacturing system for lack of
studies of manufacturing systems diagnosability for quality control and
diagnosis ability of partially diagnosable systems. Diagnosability
indexes are constructed for a partially diagnosable system. The validity
and feasibility of the proposed method and indexes are demonstrated by
an illustrative example of an assembly system with varied system
deployments. The proposed method lays a theory analysis foundation for
measurement of diagnosability, optimization of system deployment and
in-process fault diagnosis.
