摘要
饲料是发展水产养殖业的重要物质基础,饲料费用在养殖成本中所占比例达到50%左右。因此,水产养殖经济效益的好坏在很大程度上取决于饲料选择是否合理。研究旨在探讨如何选择鲍鱼饲料才能降低投喂成本。文章利用Excel 2007以及基于单纯形法求解线性规划算法研发的饲料投喂选择决策系统,实现了在满足鲍鱼生长所需的营养元素前提下饲料投入成本的最低。数据证明,两种方式均能有效地降低饲料成本。运用计算机求解线性规划问题是寻求最优解的有效手段。
Feed is an important material foundation for the development of aquaculture, but feed cost reaches about 50% of total costs. Therefore, the economic benefits of aquaculture depend largely on whether feed choice is reasonable. The aim of this study is to investigate how to choose the abalone feed to reduce feeding cost. This article uses Excel 2007 and develops a feeding selection decision system based on the simplex method algorithm for linear program- ruing to make sure that feed cost is the lowest under the premise of meeting the i^quired nutritional elements for the growth of abalone. Data shows, these two methods can effectively reduce the cost of feed. And using computer for solving linear programming problem is effective means to find the optimal solution.
