TRL is determined during a technology readiness assessment (TRA) that examines program concepts, technology requirements, and demonstrated technology capabilities. TRLs are based on a scale from 1 to 9 with 9 being the most mature technology. [1] TRL was developed at NASA during the 1970s.

Assessing Hardware CTEs Applying the TRL definitions to assess the maturity of hardware technologies appears to be straightforward. For a particular technology, evaluators assign the level of technical readiness that best describes the accomplishments and evidence according to the TRL definitions.

2015年10月1日 · TRL 9 and TRL 10 are distinguished by the duration of operations: where TRL 9 requires only a single successful implementation/use, TRL 10 requires user confidence levels to be built through repeated use and (if applicable) a certification process.

制造成熟度等级（MRL，Manufacturing Readiness Level）分为10级（见上表），主要从技术和工业基础、设计、材料、成本和投资、工艺能力和控制、质量管理、制造人员、设施和制造管理9大制造风险因素及20个子因素开展评价。

2023年9月27日 · Technology Readiness Levels (TRL) are a type of measurement system used to assess the maturity level of a particular technology. Each technology project is evaluated against the parameters for each technology level and is then assigned a TRL rating based on the projects progress. There are nine technology readiness levels.

2024年5月2日 · Definition: Technology Readiness Levels (TRL) are a method used to measure and assess the maturity of a particular technology. They allow engineers, managers and …

技术就绪度也称 技术成熟度 （TRL），什么是技术就绪度（成熟度）呢？ 根据 GB/T 22900-2009 《科学技术研究项目评价通则》中对“技术就绪水平”的定义：工作分解单元技术成熟程度 ；根据 GJB 7688-2012 《装备技术成熟度等级划分及定义》中对“技术成熟度”的 ...

One of the obstacles to achieving a cost-effective high-reliability paradigm has been the need to reinvent the command and data handling infrastructure on a spacecraft by spacecraft basis. The availability of a family of commercial spacecraft avionics units with extensive reliable flight heritage offers an attractive approach to efficiently implement a spacecraft bus tailored to support ...

The TRL describes the performance history of a given system, subsystem, or component relative to a set of levels first described at NASA HQ in the 1980s. The TRL describes the state of a given technology and provides a baseline from which maturity is gauged and advancement defined.

2018年6月19日 · 技术就绪指数（TRL，Technology Readiness Index）最初为美国国防部使用，后为NASA以及很多美国企业所采用，技术就绪指数用于评价一项技术的成熟水平，通常分为九个评价级别，第一级指技术还非常不成熟，第九级则为完全成熟的技术。
