CONSENSUS ANALYSIS MODEL FOR ENVIRONMENTAL MANAGEMENT WITH FUZZY LINGUISTIC VARIABLES

摘要

There are many criteria that must be considered in environmental decision making problems, such as the environmental, economical, social factors, among others. However, since these criteria are often conflicting, it is extremely difficult and complex to make decisions regarding environmental problems. This study proposes an approach for quantifying the degree of consensus of stakeholders and attempts to find a compromise solution between the stakeholders. This study integrates fuzzy theory and linguistic variables to develop a consensus analysis model. The opinions of each stakeholder are understood through the questionnaires and then the degree of consensus of the stakeholder is quantified for all alternatives. An example is presented to illustrate this consensus analysis model. This model can quantify the degree of consensus of the stakeholders for alternatives and attempts to seek a balance between the scientific decision making model and stakeholder value. The source of possible conflicts can also be determined in this model. The model presented here provides a useful tool for aiding decision making for real world environmental management problems.
