【摘要】：基于第十一屆"華為杯"全國研究生數(shù)學(xué)建模競賽D題,在滿足營養(yǎng)健康需要的前提下,就購買果蔬成本最少問題,建立線性優(yōu)化模型,之后利用遍歷搜索方法,分區(qū)域、分季節(jié)求解出農(nóng)村、城市一年中不同季節(jié)的果蔬人均消費(fèi)量及最低購買成本.最后考慮到居民人體的均衡營養(yǎng)、進(jìn)出口貿(mào)易、種植面積等因素,建立購買成本最低一種植者收益最大的雙目標(biāo)優(yōu)化模型,得出近幾年各種果蔬合理的人均消費(fèi)量,進(jìn)一步就2020主要果蔬的種植面積提出建議.
[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.
