基于IAFA-BP的门式起重机技术特性权重预测OA

Considering the lack of discussion on the relationship between functional requirements and technical characteristics in the design process of gantry crane in existing researches,in this paper,a weight prediction model of technical characteristics of gantry crane based on improved adaptive firefly algorithm and optimized BP neural network is proposed.By analyzing the relationship between functional requirements and technical characteristics of gantry crane,the weight of technical characteristics is predicted according to the importance of functional requirements,and the product adaptability design of gantry crane is realized.In addition,in order to improve the accuracy of the technical characteristics prediction of the gantry crane,an improved adaptive firefly optimization algorithm(IAFA)is proposed to optimize the weights and thresholds of the BP neural network and verify the effectiveness of the model.The comparison with the traditional model shows that this model has higher prediction accuracy.
