【摘要】：基于第十一届"华为杯"全国研究生数学建模竞赛D题,在满足营养健康需要的前提下,就购买果蔬成本最少问题,建立线性优化模型,之后利用遍历搜索方法,分区域、分季节求解出农村、城市一年中不同季节的果蔬人均消费量及最低购买成本.最后考虑到居民人体的均衡营养、进出口贸易、种植面积等因素,建立购买成本最低一种植者收益最大的双目标优化模型,得出近几年各种果蔬合理的人均消费量,进一步就2020主要果蔬的种植面积提出建议.
[Abstract]:Based on title D of the 11th "Huawei Cup" National Graduate Mathematical Modeling Competition, under the premise of satisfying the nutritional and health needs, a linear optimization model is established for the minimum cost of purchasing fruits and vegetables, and then the traversal search method is used to divide into regions. The per capita consumption of fruits and vegetables and the lowest purchase cost in rural areas and cities in different seasons of the year are solved by season. Finally, considering the balanced nutrition of the human body, import and export trade, planting area and other factors, a two-objective optimization model with the lowest purchase cost and the greatest income for growers is established, and the reasonable per capita consumption of all kinds of fruits and vegetables is obtained in recent years. Further suggestions on the planting area of main fruits and vegetables in 2020 were put forward.
