Abstract：To mitigate the R&D risk,it is necessary to study whether eVTOL project can be productization.Using the im-proved new product assessment index system,and the Gray Correlation-Least Square(GC-LS)method determines the productiza-tion index of eVTOL project.This method effectively attenuates the influence of subjectivity in the model and analytic hierarchy pro-cess(AHP).This paper estimates the productization index of 15 publicly available electric Vertical Take-Off and Landing(eV-TOL)projects.14 cases are used to determine the weights,while the last case are used to validate the effectiveness of the weights.Results:1)The simulated evaluation results were in good agreement with the actual situation.2)The top three optimal weights are:R&D progress,safety and social acceptance.Conclusion:1)The GC-LS method gives reasonable optimized weight factors.2)R&D progress,safety and social acceptance play relatively more important roles in the productization index of eVTOL projects.3)Utiliz-ing the GC-LS method enables convenient and objective assessment for eVTOL project productization index.
