Comparison of efficiency based on the qualitative decision-making method of autoclave and non-autoclave technologies for the manufacture of carbon-fiber aircraft structures such as aircraft wing planes B787, A350, MC-21, Cseries. The differences and advantages in the serial production of prepreg-autoclave and VARTM technological process.  The comparison was carried out on sufficient presentational basis of criteria of two levels using combinatorial and decomposition research method. Each variant of the process is characterized by evaluations according to selection criteria. Their scores are vector assessment of the criteria based on expert judgment and opinion of the decision maker. Noted that each option has own boundaries of compatibility and practical application.
