Abstract: A reliability management system and its operation method is presented. The reliability management system comprises instructions stored in a computer-readable non-transitory storage medium, with said instructions executable by one or more hardware processors communicating with the storage medium, the system comprises a reliability manager and a Reliability Test Requestor (RTR). The reliability manager receives a test equipment request from the RTR and sends corresponding test equipment information to the RTR. The RTR sends a test equipment request to the reliability manager based on product information of a test product it receives, and receives test data from a corresponding test equipment according to the test equipment information received from the reliability manager. The RTR also processes the test data to generate a test report, and determines whether the test product passed a reliability test based on the test report. This inventive concept realizes an automatic management on reliability tests.
