When farmers must make economic decisions, three competing goals must be considered: maximization of profit, avoidance of risk, and personal satisfaction. If a decision has a relatively long time-frame, then the time value of costs and of benefits also must be considered. There are a variety of ways to structure the comparison between disease control programs. If disease is endemic, a partial budget analysis is recommended. If, instead, probabilities must be included in the calculations, then the recommendation is to use pay-off table analysis or to draw a decision tree (the latter especially if there are sequences of decisions).
当农民必须做出经济决策时，必须考虑三个相互竞争的目标：利润最大化、风险规避和个人满意度。如果决策具有相对较长的时间框架，那么成本和收益的时间价值也必须予以考虑。有多种方法来构建疾病控制项目之间的比较。如果疾病是地方性的，建议进行局部预算分析。相反，如果计算中必须包含概率，那么建议使用收益表分析或绘制决策树（如果有一系列决策，后者尤为适用）。
