The assessment of technology-readiness level is widely used in the multi-disciplinary manufacturing field. The identification of critical technical elements is a key step in the assessment of technology-ready level, and it is an important guarantee to reduce risks in the project or product development process and reduce development costs. The identification of traditional critical technical elements generally adopts the expert scoring method. Through discussion, the list of critical technical elements of final consistency is obtained. The results are subjective and uncertain, resulting in the loss or redundancy of critical technical elements, which directly affects the key to technical readiness. Quantitative identification of technical elements. To this end, this paper proposes a method for identifying critical technical elements using the AHP principle. Firstly, the judgment matrix is established according to the criterion and the importance degree scale. The consistency matrix is used to check and adjust the judgment matrix according to the consistency ratio. Then the summation method and the square root method are used to solve the importance of each sub-technical element. Finally, according to the importance degree. Quantitative evaluation results identify critical technical elements and validate their validity by example pairs. The results show that the method combines qualitative analysis with quantitative analysis and has good engineering application value.
