A Novel Two-Stage Method for Collaboratively Scheduling of Steel Production and Energy in Steelmaking and Continuous Casting Processes

摘要

Taking account of time dependent electricity prices, this paper proposes discrete-time Resource Task Network (RTN) formulations to deal with collaborative scheduling of steel production and energy in steelmaking and continuous casting (SCC) problem. Due to complexity and difficulty of a large-scale SCC problem, a novel two stage method with different scheduling units is proposed to solve the model faster and more effective. The numeric experiments show that the two-stage method is very efficient and practical in the realistic steel and iron enterprises.
