中小规模农产品时间柔性生产计划模型

A plan model of medium and small-scale agricultural production with time flexibility

考虑农产品生产时间的柔性特征,研究中小规模农产品生产计划,以实现生产周期收益最大化目标。利用图论将运用0-1型整数规划构建的农产品生产计划数学模型转换为网络模型,并运用Dijkstra算法对网络模型进行求解和优选策略——农产品生产计划,通过具体实例诠释了农产品生产计划拟订过程。研究表明,农产品生产计划模型将有助于农民专业合作社、农业企业等农村经济实体更加科学、合理的决策。

Considering the time flexibility of agricultural production,the medium and small-scale agricultural production plan was studied to maximize the income in the production cycle. Firstly,0-1 integer programming was used to build the mathematical model of agricultural production plan,which was translated into the network model based on graph theory. Then the Dijkstra algorithm was applied to solve the network model,and find the optimal strategy,namely an agricultural production plan. Finally,with the help of practical examples,the process to make an agricultural production plan was annotated. The results showed that the plan model helped to make scientific and reasonable decision for rural economic entities,such as farmers＇ professional cooperatives,agricultural enterprises and so on.
