Embodiment

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

[0055] Step 1: Obtain the correction factor of multi-source data parameters

[0056] It is known that a product has been tested for 3 times before the reliability test. The test data are (81,84), (115,125), (101,113), and the corresponding correction factors are k respectively. 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 minimum input sample size is 23, and the number of successes required is 21.

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

[0060] Step three: weighing the cost of the experiment

[0061] Know the cost of each product C s 20,000 yuan, each test cost C t 10,000 yuan, C Loss 1 million, the risks and costs corresponding to different sample sizes are calculated as:

Abstract

The invention discloses a multi-source data-based reliability test design and decision-making method for a success or failure product. The method comprises the following multiple steps of 1, obtaining a correction factor of a multi-source data parameter; 2, building a test evaluation model; 3, performing test cost tradeoff; and 4, performing test scheme and plan decision-making. According to the method, multi-source data information of the success or failure product can be comprehensively utilized and a reasonable test scheme is made based on the multi-source data information; and a sample amount can be increased, so that the designed test scheme can achieve an excepted effect with relatively low cost.

Description

Technical field [0001] The invention is a method for designing the reliability test of the success-failure product by using multi-source success-failure data and introducing parameter conversion coefficients to provide a decision-making basis for the implementation of the product test. In this way, data from various sources in the product development process can be fully utilized and reasonably planned to reduce the cost of testing while ensuring the accuracy of the evaluation, which belongs to the field of quality and reliability. Background technique [0002] In production and life, success-failure products are widely used, such as rockets, airbags, fire extinguishers, etc. The reliability assessment of them is mainly based on the use of success and failure data such as "success" and "failure"; in addition to success or failure products, When assessing indicators such as the mission reliability of complex large systems (such as airplanes), the number of mission "successes" and ...
