| Abstract: | Reconfigurable Manufacturing Systems (RMS) will be a primary technology in future manufacturing systems. The portability of the equipment in RMS requires higher quality to maintain operating performance. But the ramp up effect, the degeneracy effect and other elements make the operation of the system rather complex. Therefore, system diagnosis is needed to keep the system reconfigurable. This paper defines the in process diagnosis ability of the quality defects and equipment failures for on line research. In addition, it presents measures of system operating performance by C ps (process scattering capacity coefficient) and C pe (process eccentricity capacity coefficient) to evaluate and further control the system. It also discusses the identification of recessive failures. |
