Identifying Least‐Cost Sources of Required Fertilizer Nutrients
用线性规划模型帮农户在满足肥料需求时，权衡施用成本与混合费用，找到最省钱方案。计算机辅助决策工具对农户有实用价值。
Abstract Agricultural producers should evaluate trade‐offs between application costs and blending fees when applying two or more fertilizer mixtures to satisfy their ex ante fertilizer requirements in an economical manner. This decision situation is modeled using a linear programming procedure designed for practical use as a computerized decision‐making aid. Results from a trial application of the methodology suggest this aid can be of significant value to producers confronted with such decisions.
