为恢复受放射性核素污染的水生生态系统而采取的干预措施可减少个人和集体辐射剂量，但也可能造成有害的生态、社会和经济影响。决策者在选择对策之前必须仔细评估可能的影响，因此决策分析方法构成了水生态系统污染后对干预策略进行排序的重要辅助手段。我们描述了MOIRA，一个决策支持系统，用于确定最佳的补救策略，以恢复意外引入放射性物质后的水系统。MOIRA包括一个基于多属性价值模型的评估模块，用于对备选方案进行排名，以及一个用于执行多参数敏感性分析的模块，无论是权重还是价值，都可以让我们深入了解问题。这个问题是确定性，因为用于量化对策影响的模型的验证表明，在政策effects.The系统的不确定性很小，是在一个基于PC的决策支持系统，它允许包括所有相关的信息。
Interventions to restore radionuclide contaminated aquatic ecosystems may reduce individual and collective radiation doses, but may also result in detrimental ecological, social and economic effects. Decision makers must carefully evaluate possible impacts before choosing a countermeasure, hence decision analysis methods constitute an important aid to rank intervention strategies after the contamination of an aquatic ecosystem. We describe MOIRA, a decision support system for the identification of optimal remedial strategies to restore water systems after accidental introduction of radioactive substances. MOIRA includes an evaluation module based on a multi-attribute value model to rank alternatives and a module to perform multiparametric sensitivity analyses, both with respect to weights and values, to allow us to gain insights into the problem. The problem is under certainty since the validation of models used to quantify countermeasure impacts suggests little uncertainty in policy effects.The system is implemented in a PC based decision support system which allows the inclusion of all relevant information.
