Risk assessment method and device

The invention provides a risk assessment method and device, which can be applied to the field of equipment management. The method comprises the following steps: acquiring equipment information of to-be-evaluated target equipment, wherein the equipment information comprises a plurality of parameters influencing offline of the target equipment; based on the multiple parameters and a predefined first mapping relation, multiple pieces of risk index data are obtained, and the first mapping relation is used for indicating a mapping relation between multiple values of each parameter in the multiple parameters and the multiple pieces of risk index data; and determining the risk level of the target equipment based on the multiple pieces of risk index data and the risk assessment model. By comprehensively considering multiple parameters influencing offline of the target equipment, the risk of the target equipment can be reasonably evaluated, so that the target equipment is reasonably replaced, potential safety hazards
