Problems solved by technology

However, the current research results are mainly aimed at the energy optimization problem under the parameter determination, ignoring the uncertain factors in the actual production process, such as the uncertain fluctuation of energy demand in the production system, the uncertain change of energy price and the internal equipment of the system. Uncertain failure, etc.
The existence of these uncertain factors makes the deterministic model unable to effectively define the optimization scheduling problem of the iron and steel enterprise energy system, which may cause the final optimization scheme to be inconsistent with the actual situation, and the operability is poor
