Embodiment Construction
[0088] The hierarchical optimization control method for the whole process of hydrometallurgy is characterized in that under the condition that the production management department determines the total output and total consumption, the optimization control problem of the whole process is divided into two parts: process-level index optimization and process-level loop setting optimization. To realize the multi-level structure, that is, firstly optimize the indicators of each key production process, and then realize the optimization of the key control loop setting of each process on the basis of the optimization results of the process indicators; The correlation model of each process index, with the goal of maximizing the economic benefits of the whole process, takes the process index as the decision variable, establishes the process index optimization model to realize the process index optimization; on the basis of the process model of each process, introduces the process index opt...

The invention provides a wet metallurgy full-flow layered optimization control technology. When a production management department determines gross output and total consumption, a full-flow optimization control problem is solved by a two-layered structure of procedure-level index optimization and process-level loop setting optimization. Firstly, various procedure index correlation modules for describing relations between various procedure outputs and minimal consumption of the wet metallurgy are established; and then, based on various procedure processing modules, procedure processing optimization modules are established and solved, and critical control loop setting optimization is realized further. The invention also provides a software system employing the full-flow optimization control technology, and the software system comprises a main program, a database and an interface. The invention is applied to some production flow of the wet metallurgy, thereby reducing production cost and improving economic benefits.
Description
