Problems solved by technology

Therefore, it is necessary to design a corresponding reliability test, obtain and verify the reliability index of the product within the required credible range, and verify the reliability index that meets a certain degree of confidence usually requires a certain amount of samples to be realized. In the actual development process, due to the limitation of funds, time and other factors, it is often difficult to meet the requirements of sample size

Embodiment

[0054] Now through the application of a certain system, the method of this patent is described.

[0055] Step 1. Obtain the correction factor of the multi-source data parameter

[0056] It is known that a product has been tested 3 times before the reliability test, and the test data are (81,84), (115,125), (101,113), and the corresponding correction factors are k 1 =0.894,k 2 =0.956,k 3 = 0.994.

[0057] Step 2: Establish a test evaluation model

[0058] It can be calculated by formulas (6) and (8) to satisfy γ=0.9, R L =0.865, the sample size that requires the least input is 23, and the required number of successes is 21.

[0059] Note: If conventional methods are used, at least 51 samples should be invested in high-risk situations.

[0060] Step 3. Cost trade-off of trials

[0061] The cost C of each product is known s It is 20,000 yuan, and the cost of each test is C t10,000 yuan, C Loss is 1 million, the calculated risks and costs corresponding to different sampl...

Abstract

The invention discloses a reliability test design and decision-making method for a success-or-fail product based on multi-source data, which comprises the following steps: Step 1, obtaining correction factors of multi-source data parameters; Step 2, establishing a test evaluation model; Step 3 , test cost trade-off; step 4, test plan and planning decision; the present invention can comprehensively utilize the multi-source data information of success or failure products, and formulate a reasonable test plan based on this; due to the ability to expand the sample size, the designed The experimental program can achieve the desired effect at a relatively low cost.

Description

technical field [0001] The invention is a method for designing reliability tests of success-or-failure products by using multi-source success-or-failure data and introducing parameter conversion coefficients, so as to provide decision-making basis for product test implementation. In this way, the data from various sources in the product development process can be fully utilized and rationally planned, and the accuracy of the evaluation can be ensured while reducing the test cost, which belongs to the field of quality and reliability. Background technique [0002] In production and life, success-or-failure products are widely used, such as rockets, airbags, fire extinguishers, etc., and their reliability evaluation mainly uses success-or-failure data such as "success" and "failure"; except for success-or-failure products, When assessing the mission reliability and other indicators of complex large systems (such as aircraft), the number of mission "success" and "failure" data ...
