大型的矿区煤质与选煤计算机综合管理系统(三)——重选产品结构优化算法研究

A Large-scale Coal Quality and Preparation Computer Comprehensive Management System for Coal Mining District-(Part 3) Study on Optimization Algorithm of Gravity Separation Product Structure

在矿区煤质与选煤计算机综合管理系统中,产品结构优化是重要的决策支持功能之一。文章针对类型众多和复杂的重选产品结构优化问题,从简单到复杂,选取了4种比较有代表性的优化问题进行研究。为了便于建立数学模型,在做出必要的假设和条件限定的前提下,对这4种问题进行了分析和简化,并根据其优化目标和约束条件的不同,分别对其进行公式推导和建模,最后给出了初步的求解思路。

In the light of the complex questions about optimization of gravity separation product structure,the paper selected four representatively questions from simple to complex for research one.In order to establish mathematic model easily,the four questions are analyzed and simplified under the necessary conditions of have make hypothesis and restriction.According to the different of optimization goal and constraint condition,the paper makes formula derivation and model building separately for the questions,and finally gives out preliminary solving methods.
