线性规划优化饲料配方的模型及其软件设计

Design on model and software of linear programming to optimizing feed formula

线性规划是广泛应用的饲料配方优化技术,能够解决多种原料配比、满足多个营养指标要求,同时符合饲料成本最低的要求。为了发挥线性规划和现代信息技术在饲料配方中的双重优势,本文从三个方面展开研究:首先,设计了线性规划优化饲料配方模型,作为进一步研究的基础;然后,设计了线性规划优化饲料配方求解流程,针对单纯形法计算机求解存在的问题,深入研究了改进单纯形法;最后,设计了线性规划优化饲料配方软件,在主程序界面模型相关数据后,就可得到计算结果。

Linear programming is the widely used optimizing feed formula technology that can solve a variety of raw material ratios,meet multiple nutritional requirements,and accord with the minimum feed cost requirements. In order to give play to the dual advantages of linear programming and modern information technology in feed formula,this paper starts from three aspects ：fi rst,the model on linear programming to optimizing feed formula is designed as the basis for further research;then,linear programming to optimizing feed formula is designed. The solution process is based on the simplex method computer to solve the problems,and the improved simplex method is deeply studied. Finally,the linear programming to optimizing feed formula software is designed. After the relevant data of the main program interface model,the calculation results can be obtained.
