Abstract: This paper focuses on the issue of“Photographing and Making Money” task given by the National College Students Mathematical Modeling Contest in Modeling in 2017.Through the method of multiple linear regression analysis,the pricing law function of the task is established to explore the law of task pricing and analyze the reasons why the task is not completed.Based on the existing pricing law function,a multivariate logistics logistic regression function is introduced to correct the original pricing scheme,and an improved new task pricing scheme is obtained.In connection with the actual situation,consider using SPSS for task clustering and subcontracting processing and formulating package preferential policies to modify the pricing model.compared with the original program results,the new program has a better implementation effect.
