Research of Manufacturing Readiness Level and Its Application in Chinese Space Engineering

This paper introduces the method of MRLs （Manufacturing Readiness Levels ） applied in United States DoD （Department of Defense）, and analyzes its application value in improving manufacturing capability and manufacturing risk management in Chinese space engineering. First- ly, the relationship between the MRLs, TRLs （technology readiness levels） and PM （product maturity） is explained. Secondly, the theoretical limitations of the MRLs in mass production are analyzed. Thirdly, in accordance with the characteristics of Chinese space industry which are multiple manufacturing types, manufacturing difficulties and mass production, modified definitions of MRLs and the assessment method of manufacturing readiness are suggested. Finally, suggestions are given to the research of MRLs, the trial application of MRLs, the establishment of MRL standards and a mechanism for manufacturing maturation improvement in Chinese space industry.
