Development Of Overall Performance Effectiveness In Job Shop Manufacturing Process

Overall equipment effectiveness (OEE) is implemented by the case company,an aerospace part manufacturing company, to encourage machines to operate all the time at the ideal speed and produce no quality defect in extreme case.However,integration between workstations and transporting activities,deviat...
