The invention provides a knowledge representation-based steel production scheduling model matching method which specifically comprises the following steps: 1) a production plan is input, and the production plan comprises a production order and a hot delivery and hot charging production plan given by a hot rolling workshop; 2) a slab quantity is calculated; the order is decomposed based on steel types, slab specifications and delivery dates; 3) a casting order is arranged, and all castings are ordered according to difference between continuous caster usage conditions and order delivery dates; 4) characteristic signals are collected, and characteristic signals of a key position of a bottom layer device can be obtained via a corresponding sensor; 5) a crown block optimization algorithm is performed; 6) a transport task state is switched; 7) a plan is rearranged; 8) the adjusted plan is displayed to a scheduling worker in a form of a Gantt chart. Via the matching method, production safety of steel making processe
