The embodiment of the invention provides a case reasoning-based coping scheme selection method and system, and belongs to the technical field of data mining. The selection method comprises the following steps: acquiring a feature attribute of a current event; determining the weight of the feature attribute; calculating the similarity between the current event and each historical event according to the feature attributes and the corresponding weights; screening out the historical events with the similarity greater than or equal to a preset threshold value to form a similar case set; calculating implementation result utility and perception utility of each historical event in the similar case set; calculating a comprehensive evaluation value of each historical event according to the implementation result utility and the perception utility; and selecting the historical event as an optimal matching event of the current event according to the comprehensive evaluation value. According to the selection method and sys
