Artificial Intelligence-based Tolerance Assessment Methods

摘要

Artificial intelligence(AI) is utilized to assess the form error on the basis of nonlinear optimization, such as artificial neural network(ANN) and genetic algorithm(GA). The ANN-based method uses the structure of network (connection weights and nodes thresholds) to memorize the information of specific problems and fulfills the optimization assignment. And the GA-based method simulated the evolution process of struggle for survival to obtain the optimal objective. The computation results indicate that both ANN and GA are effective for nonlinear optimization of tolerance assessment.
