Identify and Prioritize he Factors Affecting on the Drying of Urmia Lake with Integrated Fuzzy DEMATEL & Analytic Network Process (F.D.ANP)

Drying of Lake of Urmia will have irrecoverable effects on the environment of the region. In this study, with
due attention to the requirements of the problem, first we identify the parameters affecting the drying of Urmia
Lake, then we propose a conceptual model of network structure. As the parameters of the conceptual model
are interdependent, we use an integrated DEMATEL and Fuzzy Analytic Network Process technique in order to
assess the impacts and impressionability of those parameters as well as relative importance weights and ranking
thereof. The results indicated that among main criteria, "management aspect" had the greatest impact and the
maximum importance weight. Also among sub-criteria, "lack of strategic plan about the preservation of lake in
the past years and updating it" ranked as first in terms of intensity of impacts. Moreover, "Lack of attention to
the environment among managers and focusing on short-term goals" acquired the maximum importance weight.
According to the results, it seems necessary for the managers to switch from mere economical attitude, towards
environmental protective and preservative attitude
