The invention relates to a hot rolling plan arrangement method, and belongs to the technical field of metallurgical continuous rolling. The method includes: setting a constraint function, establishing a rolling plan model, solving the rolling plan model, performing programming by employing a computer programming technology, and establishing a continuous casting and rolling production, organization, and management mode. Compared with the prior art, the beneficial effects of the method are that the plan making is flexible, mixed arrangement of different steel kinds, different thicknesses, and different widths can be performed, and crossed rolling is realized; the hot direct rolling rate of hot-rolled slabs is high, the heating time of cold-rolled plates is reduced, and energy is saved; and the function of six-in-one by three machines of the casting billet can be fully achieved, the 215OASP production line realizes tight combination of three processes including steel production, continuous casting, and rolling, and the goal of promoting energy saving and consumption reduction of steel products is achieved.
