Abstract:The Technology Readiness Level (TRL) evaluation, based on project decomposition and key technology identification, emphasizes the transformation of technologies through various development stages. It directly reveals the progress and target completion of projects, innovating project management by enriching evaluation details for each stage of technological research and development. Currently, a well-developed definition of TRL9 has been formed and is primarily applied in industry. However, measuring the effectiveness of science and technology projects at the management level remains unaddressed. Therefore, this study aims to improve the management of national major projects by enriching TRL evaluation details and optimizing the evaluation process at all stages of technology development through a case study. Firstly, key special project of Key Technology and Intelligent Agricultural Equipment of Factory Agriculture was used as a case study to analyze the TRL management system. The study reviewed the development of TRL concepts and domestic and international research applications. It then systematically idenitified and evaluated the technical and normative requirements in the R&D chain of principle conception, technology validation, simulated environment testing, practical application. Secondly, according to the definition of TRL level 9 by the National Aeronautics and Space Administration (NASA) of the United States, a technology-readiness evaluation system was constructed from the three key elements, namely, the TRL evaluation team, the evaluated organization and the evaluating object. This system covered the following three domains: technology, assessment of technological achievements and innovativeness, and application performance. In particular, it encompassed technical indicators, indicators of technical achievement and innovativeness, and indicators of application performance. Finally, considering the operational characteristics of the evaluation organization, we designed the technical readiness evaluation process through expert consultation. Operational guidelines were developed from two dimensions: the technical readiness assessment team and evaluated institutions. The study established the general TRL standard, TRL index system, and reference indexes for rating points based on project characteristics, eventually developing the technical readiness management system for the key project "Key Technology of Factory Farming and Intelligent Agricultural Machinery and Equipment." Based on the conclusions, the study offers recommendations to enhance TRL implementation in S&T project management. These include conducting pilots and promotions in agriculture, increasing awareness and training on evaluation methodology, integrating TRL with other project management methods, and accelerating informatization and technological development.
