A Fuzzy Multistage Control Model for Sustainable Regional Agricultural Development: Effectiveness and Stability

Abstract

As an important further extension of a multistage fuzzy control model of stable sustainable regional agriculture development proposed by the authors, the stability requirement is added which stands for a clear preference of the stakeholders, i.e. farmers, agri-food producers, local, regional and central authorities, food producers and processors, etc. for a limited variability of crucial development indicators and parameters. A dynamic programming model is proposed which reflects many crucial aspects of the respective systems. proicessses and their characteristics, notably the life quality indicators, and which are subject to objective, by the authorities, and subjective, by the inhabitants, evaluations and assessments a considerable part of which is perception oriented. An additional requirement of a limited variability of crucial development indicators, parameters, etc. is added. As an example the determination of the best (optimal) investment policy under different development scenarios, and subject to objective and subjective evaluations, is shown.
