Method and device for processing production and operation data of oil refinery

The invention relates to an oil refinery production operation data processing method and device. The method comprises the following steps: determining oil refinery production operation parameters; the parameters comprise integer parameters; establishing an integer parameter constraint function according to the integer parameter; establishing an integer parameter sequence table according to the time sequence of the integer parameters applied in the production operation process of the oil refinery; determining a plurality of branch chains in one-to-one correspondence with the plurality of integer parameter constraint functions according to the integer parameter sequence table and a preset integer parameter value sequence; determining boundary solutions of the plurality of branch chains in a pre-established profit optimization model; traversing all the branch chains, and optimizing the boundary solution of the previous branch chain by using the boundary solution of the next branch chain; according to the optimiz
