Take-out delivery time prediction method and device

An embodiment of the invention provides a take-out delivery time prediction method and a take-out delivery time prediction device. The take-out delivery time prediction method comprises the steps of:acquiring order information of a take-out order, and determining historical influencing factors and current influencing factors corresponding to the take-out order according to the order information,wherein the historical influencing factors are determined based on historical take-out delivery data; and determining delivery duration of the take-out order according to the historical influencing factors and the current influencing factors of the take-out order and a nonlinear prediction model. Since the historical influencing factors and the current influencing factors influencing the take-outdelivery duration are fully considered when predicting the delivery duration of the take-out order, the take-out delivery duration can be predicted more comprehensively. Since a gradient boosting treemodel and a random forest model are combined to construct the nonlinear prediction model used for predicting delivery duration, the influence of nonlinear influencing factors on the take-out deliveryduration are fully considered, thus the nonlinear prediction model has better fitting effect, better robustness and better delivery duration prediction effect when compared with the traditional linear regression model.
