DECISION MAKING ON REGIONAL LANDFILL SITE SELECTION IN HORMOZGAN PROVINCE USING SMCE

Abstract. Landfill site selection and suitable conditions to bury hazardous wastes are among the most critical issues in modern societies. Taking several factors and limitations into account along with true decision making requires application of different decision techniques. To this end, current paper aims to make decisions about regional landfill site selection in Hormozgan province and utilizes SMCE technique combined with qualitative and quantitative criteria to select the final alternatives. To this respect, we first will describe the existing environmental situation in our study area and set the goals of our study in the framework of SMCE and will analyze the effective factors in regional landfill site selection. Then, methodological procedure of research was conducted using Delphi approach and questionnaires (in order to determine research validity, Chronbach Alpha (0.94) method was used). Spatial multi-criteria analysis model was designed in the form of criteria tree in SMCE using IL WIS software. Prioritization of respective spatial alternatives included: Bandar Abbas city with total 4 spatial alternatives (one zone with 1^st priority, one zone with 3^rd priority and two zones with 4^thpriority) was considered the first priority, Bastak city with total 3 spatial alternatives (one zone with 2^nd priority, one zone with 3^rdpriorit and one zone with 4^th priority) was the second priority and Bandar Abbas, Minab, Jask and Haji Abad cities were considered as the third priority.
