Multi-criteria decision aiding model for the evaluation of agricultural countermeasures after an accidental release of radionuclides to the environment

摘要: Multi-criteria decision aid has emerged from the operational research field as answer given to a couple of important questions encountered in complex decisions problems. Firstly, aiding tools, such methods do not replace maker with mathematical model, but support him construct his solution by describing and evaluating options. Secondly, instead using unique criterion capturing all aspects problem, multi-criteria one seeks build multiple criteria, representing several points view. This work explores application for optimising food chain countermeasure strategies after radioactive release environment. The core thesis is dedicated formulating general lines development model. includes definition potential actions, construction evaluation criteria preference modelling essentially based on results stakeholders’ process. centred management contaminated milk order provide concrete focus because its importance an ingestion pathway short term accident.Among other issues, public acceptance countermeasures key analysed detail. A comparison stochastic dominance proposed and, that, countermeasures’ ranking deduced.In assess “global preferences” taking into account ordinal method chosen. allows expressing relative qualitative way using, instance, numerical weights. Some algorithms that can be used robustness analysis are also proposed. type alternative sensitivity what concerns data uncertainty imprecision determine how if model result or conclusion obtained specific instance model’s parameters holds over entire domain acceptable values these parameters.The integrated approach makes use outranking interactive methodologies implemented tested through number case studies prototype tools.
