User operation method and device based on arithmetic expression configuration

The invention discloses a user operation method and device based on arithmetic expression configuration, and the method comprises the steps: receiving a calculation index configured by an operator, the calculation index being configured by the operator in a configuration interface based on a pre-configured calculation template and basic data; the calculation indexes comprise a parameter value list and a mathematical expression with placeholders; analyzing a mathematical expression and a parameter value list in the calculation index to obtain a calculation expression; based on the basic data, numerical calculation is carried out according to the calculation expression to obtain a calculation result, and the calculation result is used for determining a target user; and sending the calculation result to an operator terminal for display, so that an operator formulates an operation strategy according to the calculation result. According to the method and the device, the technical problems of high cost and low effi
