对偶模型在农户经营决策中的应用

Application of Dual Linear Programming Model on the Management Decision-making for Farmers

针对目前农户层面的微观决策研究不足、农户生产经营布局盲目和农业生产资源配置不合理等状况,运用对偶线性规划方法对农户的农业生产经营布局建立优化决策模型,分析以种植业为主兼顾庭院养殖的决策变量选择依据以及满足耕地资源、生产要素和营养元素平衡等条件的约束方程构建过程,利用Lindo软件对实例中的优化模型求解计算,决策得出农户最大经济效益以及相应的最优布局结构。通过对决策结果进行深入的灵敏度分析和资源影子价格分析,保证农业生产经营经济效益最大化的同时科学合理地指导农业生产资源的优化配置。表4,参18。

Aiming at inadequate research on the microcosmic decision-making on the basis of individual farmer level,blind production distribution and unreasonable resource allocation, the study analyzed the process of establishing agriculture production and management optimization model by using dual linear programming,the way of choosing the decision variables for planting-based industry considering breeding industry, and the method of constructing constraint equation which satisfied conditions such as land resource, farming factors, nutrition balance etc. By using the software Lindo to calculate an example for solution, we obtained the maximized economy benefits and optimal distribution structure. With detail analysis on the sensitivity and shadow price of dual linear programming, the method can scientifically instruct the agricultural resource allocation as well as ensure the maximal economy benefits.
