T/GDFCA 041-2021 Standard for Reliability Testing of Food Traceability Systems Based on Blockchain Technology

Scope

Scope: This standard introduces the terms and definitions of reliability testing for food traceability systems based on blockchain technology, as well as the corresponding guidelines, testing methods, and testing content. This standard applies to the reliability testing of food traceability systems based on blockchain technology. Main technical content: General reliability testing methods include the following: a) Expert review method: A subjective evaluation method. During the review, a review project form should be designed according to the object being reviewed and the purpose of the review, listing scoring columns, scores, weights, and scoring rules. A review team may consist of N experts, who will make judgments and score based on their own experience and knowledge. Then, the scores will be aggregated and calculated according to the experts' weights and statistical rules, and the resulting value will be used as the review result. The scoring rules can be graded, or they can be a value range, or another suitable rule; b) Technical testing method: An objective evaluation method. During technical testing, automated testing tools suitable for the object being tested and the testing purpose can be selected, or manual testing can be performed. The results obtained from technical testing are usually quantitative measurements; c) Mathematical calculation method: An evaluation method that uses mathematical models for calculation. During the evaluation, a suitable mathematical model should be selected according to the object being tested and the testing purpose, and then the calculation should be performed to obtain a numerical value as the evaluation result; d) User survey method: A questionnaire survey method aimed at a specific user group. During the user survey, a survey form should be designed according to the purpose of the survey and the specific user group, and the surveyed objects should fill it out and provide feedback. The number of recovered surve
