摘　　要：为探讨在饲料配方设计时如何选择合适的优化算法,文章比较了线性规划、目标规划和模糊规划等算法在鲤鱼、猪、蛋鸡配合饲料配方设计中的优化结果。结果表明:三种优化算法的结果存在显著差异。模糊规划算法在三种配合饲料配方设计中均不能满足所有营养物质水平,且计算时间最长,其优点是配方成本最低;线性规划算法和目标规划算法在三种饲料配方中均能满足所有营养物质水平,但是在配方成本和计算时间方面存在差异。在配方成本方面,目标规划算法在三种优化结果均为最高成本。在优化过程用时方面,除鲤鱼饲料配方中线性规划算法用时最短外,另外两种饲料配方中均是目标规划算法用时最短。同时,结果还表明线性规划算法和模糊规划算法会随着配方中原料和营养物质约束条件的增多而导致计算时间大幅度增加。In order to investigate the selection of appropriate optimization algorithms in feed formulation design,the optimization results of linear programming,goal programming,and fuzzy programming algorithms were compared in the context of carp,pigs and laying hens feed formulation design.The findings revealed that there were noteworthy differences in the optimization results of the three algorithms.Specifically,the fuzzy programming algorithm was unable to fulfill all the nutrient levels in the three feed formulations and had the longest computation time,yet offered the advantage of the lowest formulation cost.While both the linear programming algorithm and the goal programming algorithm were capable of satisfying all the nutrient levels in the three feed formulations,they exhibited dissimilarities in formulation cost and computation time.The goal programming algorithm yielded the highest cost among the three optimization outcomes in terms of formulation cost.In relation to the computation time expended during the optimization process,the goal programming algorithm was the shortest in the other two feed formulations,while the linear programming algorithm was the shortest in the context of the carp feed formulation.Furthermore,the results also demonstrated that an augmentation in raw material and nutrient constraint conditions in the feed formulation would result in a considerable increase in computation time for both the linear programming algorithm and the fuzzy programming algorithm.
