FUZZY RANKING FOR LANDFILL SITE SELECTION IN INDIAN CONTEXT

Landfill site selection in an urban area is critical issue in the urban planning process. It creates major impact on economy, ecology, and the environmental health of the region. With the growth of urbanization as well as the desire to live in cities, larger amount of wastes are produced. Therefore, unfortunately the problem gets bigger every day. A selection of proper waste disposal site is a function of many parameters pertaining to urban planning and Environmental aspects. The normal practice is to select a site where open space is available. Parameters pertaining to above aspects are hardly attended to. The right method of selection should have been based upon correct assessment of parametric evaluation. All parameters have various scales and values too. In order to integrate these values, fuzzy approach seems to be the reasonable selection method. Thus, the objectives of this paper are to highlight solid waste scenario in Indian context, to present the assessed parameters and to present a model of fuzzy ranking approach to solve the problem. The fuzzy multi criteria decision making (FMCDM) is used to rank different land fill sites. The solution suggested shall be a useful tool for urban environmental applications.
