摘要
以利润最大为目标,给出了稀土分离企业产品结构的优化模型。流程中包括分离作业和提纯作业,前者的质量平衡式包括各稀土元素的分配矩阵,后者包括作业的收得率。与A企业产品结构相比,文中最优解在降低产量和减少原料消耗的同时,提高了生产利润,证明了按利润分摊分离成本对产品结构决策的错误影响;构成最优解的可行产品组合必须满足物料平衡的等式约束,因而须容纳原料中的所有组分。可行产品组合是成本分析和核算的最小单元。
An optimizing nts that use joint-growth model was developed for plarare earths concentrate and separate it into individual products. This processing course included separating activities and purifying activities, mass balance of former activities being expressed with separating matrix and that of latter activities with yield rate. The solution of the model attained higher profit with lower production volume and lower consumption of the concentrate, compared with the performance of A plant in June of 2005, which indicated that dividing separating cost between two products may result in bad decision on product mix. The analysis also shows that cost report should be drawn up for each feasible product mix, which contained all the rare earth elements in the concentrate meeting the equal constraints of mass balance.
