摘要
All work of library is carried out around the readers, library visits prediction is crucial to the allocation and optimization of library human, financial, and material resources. Based on the construction of GM (1,1) model and the Back Propagation Neural Network (BPNN) model, this study established a combination model of GM (1,1)-BPNN, and takes Jiangan Library of Sichuan University as the case study, and fits the 36-month data from January 2017 to December 2019 for model verification. Results show that, in terms of library visit prediction, GM (1,1)- BPNN has smaller errors, higher prediction accuracy, and better stability than GM (1,1) or BPNN.
