Economic analysis of hazard surveillance in livestock production chains is essential for surveillance organizations (such as food safety authorities) when making scientifically based decisions on optimization of resource allocation. To enable this, quantitative decision support tools are required at two levels of analysis: (1) single-hazard surveillance system and (2) surveillance portfolio. This paper addresses the first level by presenting a conceptual approach for the economic analysis of single-hazard surveillance systems. The concept includes objective and subjective aspects of single-hazard surveillance system analysis: (1) a simulation part to derive an efficient set of surveillance setups based on the technical surveillance performance parameters (TSPPs) and the corresponding surveillance costs, i.e., objective analysis, and (2) a multi-criteria decision making model to evaluate the impacts of the hazard surveillance, i.e., subjective analysis. The conceptual approach was checked for (1) conceptual validity and (2) data validity. Issues regarding the practical use of the approach, particularly the data requirement, were discussed. We concluded that the conceptual approach is scientifically credible for economic analysis of single-hazard surveillance systems and that the practicability of the approach depends on data availability.
对畜牧生产链中的危害监测进行经济分析，对于监测组织（如食品安全当局）在基于科学做出资源分配优化决策时至关重要。为此，需要在两个分析层面使用定量决策支持工具：（1）单一危害监测系统层面和（2）监测组合层面。本文通过提出一种单一危害监测系统经济分析的概念方法来解决第一个层面的问题。该概念包括单一危害监测系统分析的客观和主观方面：（1）一个模拟部分，用于根据技术监测性能参数（TSPP）和相应的监测成本得出一组高效的监测设置，即客观分析，以及（2）一个多标准决策模型，用于评估危害监测的影响，即主观分析。对该概念方法进行了（1）概念有效性和（2）数据有效性的检验。讨论了该方法实际应用方面的问题，特别是数据要求。我们得出结论，该概念方法对于单一危害监测系统的经济分析在科学上是可信的，并且该方法的实用性取决于数据的可获得性。
