为了支持农业组织的农业管理决策，提出了田间小区种植计划布局优化模型。采用混合0-1规划技术以整体方式在每个田间小区选择下一种植作物。减少总氮排放到排水渠的下游端的田间小区表示为一个目标函数的模型，以平衡实现经济目标和环境保护。该模型可用于制定日本政府关于调整水稻种植面积和促进特定高地作物生产的政策。最后给出了一个在综合政策管理下田间小区种植计划安排的算例，并对优化模型进行了不同权重的运算。所获得的权衡曲线和相应的种植计划模式可供农业组织决策参考。
An optimization model for cropping-plan placement on field plots is presented for supporting decision-making on agricultural management by a farming organization. The mixed 0–1 programming technique is employed to select the next planting crop at each field plot in a holistic manner. Reduction of total nitrogen discharged from field plots to the downstream end of the drainage canals is expressed as an objective function of the model to balance an achievement of economic goal and environmental conservation. Some Japanese governmental policies on regulating rice cropping areas and on promoting production of particular upland field crops can be formulated in the model. A computational example of cropping-plan placement on field plots managed under integrated policies is given by operating the optimization model with various weights associated with the objectives. The procured trade-off curve and corresponding patterns of cropping-plan could be useful in the decision-making by the farming organization.
