Description

technical field [0001] The invention belongs to the technical field of reliability optimization, and in particular relates to a variational particle swarm optimization method, system, computer equipment, medium and application. Background technique [0002] At present, reliability is an important index to measure the application performance of various products in modern industrial society, and an important guarantee for the competitiveness and adaptability of various products. The requirement of medium reliability is an important embodiment of the development goal of "quality first". Therefore, improving the reliability of products has been paid more and more attention to by today's manufacturing industry. On the other hand, the cost and reliability of the product usually have a positive correlation. While ensuring the reliability index, the cost factor of the product must also be considered. Finding a balance between cost and reliability is a key way to improve product co...
