Design and application of control system for operation of stacker-reclaimers based on multi-objective optimization

This study deals with the minimization of the driving distance and maintenance cost, and the optimization of the operation of the stacker-reclaimer. First, a multi-objective optimization model for the operation of the stacker-reclaimer is presented based on the analysis of the characteristics of the operation processes. Next, the model is converted to a singleobject optimization model using the analytical hierarchy process. Then, an optimization algorithm is designed to obtain an optimal working plan. Finally, an operating control system for the stacker-reclaimer is designed based on constrained conditions and practical requirements of the sintering stockyard in an iron and steel enterprise. This system contains an optimization module for piling up and reclaiming, a chart drawing module for the stockyard recording, an automatic control module, a monitoring module, and an alarm module. The application results of the system to the operation of real stacker-reclaimers shows that the system reduces the driving distance, increases the uniformity of utilization of devices, and improves the stability of raw material.
