基于鲁棒优化模型的农产品供销问题研究

Research on Supply and Marketing of Agricultural Products Based on Robust Optimization Model

农产品的供销过程实质上就是农产品流通的过程,在区域农产品流通过程中往往会存在信息不对称的情况。由于农产品价格的季节性波动以及受外界环境的影响,对农产品的需求量很难做到准确的把握,但是可以根据历史经验知农产品的需求量满足一定的概率分布。基于此构建了农产品供销的鲁棒优化模型,并用对偶的方法得到了在不完全信息下的农产品供销模型的最优解。

The process of agricultural product supply and marketing essentially is the process of circulation of agricultural products,it exists a phenomenon in the process of regional agricultural products circulation information is asymmetric. Due to seasonal fluctuations in the prices of agricultural products and the impact of the external environment,it＇s hard to know exactly the demand of the agricultural products,but according to the historical experience,it can know the demand of agricultural products to satisfy the certain probability distribution. Based on this,the paper builds a robust optimization model of supply and marketing of agricultural products,and gets the best optimal solution of agricultural products supply and marketing model under the incomplete information with the dual method.
