Embodiment Construction

[0047] In order to better understand the present invention, the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0048] A method for optimizing the reliability sampling acceptance test scheme based on MWO, including the following steps: S1: Determine the objective function according to the purpose of the test, and establish the acceptance model of the reliability sampling acceptance test; in order to make the test accuracy good, the designed objective function is The variance of the test is the smallest, and the accelerated degradation information of the product is obtained through the accelerated test of the product, the degradation test conditions of the accelerated degradation test are recorded, and the test data at different test time points are recorded D i and the test time point T i , where i=1, 2,..., n, n is the number of test data; taking smart meters as an example, the power grid company needs to p...

Abstract

The invention relates to the technical field of reliability sampling acceptance test, in particular to an optimization method of reliability sampling acceptance test scheme based on MWO. The concretesteps include: (1) determining the objective function according to the test purpose and establishing the acceptance model of reliability sampling acceptance test; (2) determining the constraint conditions of the acceptance model according to the agreement between the producer and the user of the product; (3) MWO algorithm is used to optimize the acceptance model under the constraint condition; (4)the optimized parameters of reliability sampling acceptance test plan are obtained. The invention adopts MWO algorithm to optimize reliability sampling acceptance test scheme. The invention optimizesthe sample size, the stress intensity, the test time and the failure threshold to avoid the damage to the product caused by the excessive stress intensity, and also avoids the time cost of the acceptance due to the excessive sample size and the long test time. The invention obtains a better test effect and solves the problem of the acceptance of the batch products with high reliability and long service life.

Description

technical field [0001] The invention relates to the technical field of reliability sampling acceptance test, in particular to an optimization method of a reliability sampling acceptance test scheme based on MWO. Background technique [0002] The reliability sampling acceptance test is an accelerated stress test for testing the reliability of batch products. It is to apply one or more different stresses to certain products in a certain batch within a certain period of time, so that the products will fail or degrade. A test method for extrapolating the reliability of all products in a lot by modeling test failure or degradation data. [0003] The key to this test is how to give a reasonable test plan so that both the product manufacturer and the user can accept it. The test time, sample size, applied stress and test deadline are the keys to the test cost and reliability. factor. Therefore, it is very important to give an optimized test plan through an effective method. Howe...
