采用随机规划法进行饲料配方设计

ANIMAL RATION FORMULATED BY STOCHASTIC PROGRAMMING

采用随机规划法建立了饲料配方设计的一种数学模型．与常用的线性规划比较，该模型具有涵容原料养分含量的变异性、配方产生预期效果的可靠性大和具有开放性的优点，为饲料配方研究提供了一种新的设计方法，并举例说明了方法的应用．

This paper deals with the stochastic programming served as a mathematical model for feed formulation at the least cost. The stochastic programming model has three special advantages over common linear programming: (1) it can incorporate nutrient variability, (2) when formulating a ration ,livestock managers take the effect of the animal ration into account,and (3) it has an open system.Thus,it is a promising feed formulation technique.A practical example is given to illustrate the application of this method.
