对烧结矿性能进行分析,运用模糊数学理论、 铁矿粉的理化性能和高温性能特征数,建立了加权型评价模型,由此获得一个可以综合评价烧结矿性能的参数β.模型中权重和隶属度函数分别用Fuzzy AHP方法和指派法进行确定.利用评价模型,在对烧结矿性能和供应量进行约束的基础上,将成本最低和烧结性能最好同时作为目标函数,建立多目标非线性的配矿模型,并用粒子群优化算法和Visual Studio软件编程对模型求解,得到最优配矿方案.基于新方法得到的烧结优化配料模型,通过实际生产运用,验证了模型的可行性.%Utlizing the fuzzy mathematics, assimilation and fluidity characteristic number, the present study analyzed sinter properties comprehensively and established a weighted evaluated model to evalu-ate sinter properties with a parameter ofβ. In the evaluated model, Fuzzy AHP and the assigned meth-od were used to determine the weight and membership functions respectively. The model made both the lowest cost and the best sinter properties as objective function by limiting the sinter properties and the raw materials' supplement, which build a multi-objective and non-linear ore matching model fur-ther. And the paper used particle swarm optimization algorithm and programming with visual studio to solve the model. Through practical application in production, the sinter-optimization-supply model based on the new method was proved to be effective.
