Problems solved by technology

[0003]At present, product reliability verification tests mainly assess the basic reliability level of equipment or systems, and cannot give accurate task reliability parameters
Traditional mission reliability verification methods such as laboratory statistical tests for index verification, this method takes too long to test, consumes manpower and material resources, and cannot effectively expose problems; It is too late to give the test conclusion, unable to guide the design, and it is difficult to evaluate the product in the short term
The mission reliability index requirements generally adopt simulation verification and modeling analysis verification, and the mission reliability parameters and design of the product have not yet been actually verified.

Abstract

The invention relates to a task reliability evaluation method and device, computer equipment and a storage medium. The method comprises the steps of obtaining task reliability design data of a product, performing task reliability design analysis on the product according to the task reliability design data, determining a to-be-verified module of the product, and determining a verification demand and a test demand of the to-be-verified module, the verification demand comprising a target task, a fault mode and a fault rate corresponding to the fault mode, based on the verification demand and the test demand, constructing a fault injection test case, and performing a fault injection test on the to-be-verified module according to the fault injection test case to obtain test result data, the test result data including target task completion data of the product in the fault mode, and determining a task reliability evaluation result of the product according to the target task completion data and the fault rate of the product in each fault mode. By adopting the method, the task reliability parameters can be verified and quantified.

Description

technical field [0001] The present application relates to the technical field of product testing, and in particular, to a task reliability evaluation method, apparatus, computer equipment, storage medium and computer program product. Background technique [0002] Mission reliability refers to the ability of a product to complete a specified function within a specified mission profile, and characterizes the ability of a product to successfully complete a mission. In the development process of modern electronic products, in addition to the high requirements of performance indicators, the requirements of the product's mission reliability are getting higher and higher. [0003] At present, the product reliability verification test mainly evaluates the basic reliability level of the equipment or system, and cannot give accurate mission reliability parameters. The traditional implementation method of mission reliability verification, such as the laboratory statistical test for in...
