Offline solving method and device and online decision-making method and device

The embodiment of the invention provides an offline solving method and device and an online decision-making method and device. The offline solving method comprises the following steps: updating a data table; the data table comprises object data required for modeling; analyzing the dynamically updated constraint table; wherein the constraint table is generated in advance, each row in the constraint table corresponds to one constraint condition, and each column corresponds to one syntax element; each syntax element is an element which is abstracted according to description languages of various types of constraint conditions and is universal in the various constraint conditions; modeling according to the data in the data table and each constraint condition in the constraint table to obtain a model algorithm, and obtaining an index parameter corresponding to each constraint condition; and outputting the model algorithm and the index parameters. According to the embodiment of the invention, the implementation proc
