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

This thesis explores the application of multi-criteria decision aid methods for the decision problem on food chain countermeasure strategies after a radioactive release to the environment. The core of the thesis is dedicated to formulating general lines for the development of a multi-criteria decision aid model. This includes the definition and generation of potential actions, construction of evaluation criteria and preference modelling and is essentially based on the results of a stakeholders’ process. The work is centred on the management of contaminated milk in order to provide a concrete focus and because of its importance as an ingestion pathway in short term after an accident. The integrated multi-criteria decision aid approach proposed makes use of outranking and interactive methods and is implemented and tested through a number of case studies and prototype tools.
