【Abstract】 There are some associations between potential failures and running states of elevators. According to the key elements of elevators, the assessment model based on logistic regression algorithm is established by choosing assessment parameters and characterization reflecting the status of elevators. Through analyzing the evaluating model’s basic principles, preprocessing original data, introducing the methods of penalty factor, cross validation, and high order pseudo linear, unbalanced data and difference issues are solved, and the evaluating model’s accuracy is improved, thus the realtime supervision and pre-warning of elevators’ status are established.更多还原
