Fuzzy multicriteria disposal method and site selection for municipal solid waste (Shiraz City, Southwestern Iran)

摘要

The Sanitary landfill of urban waste and other engineering project, needs basic information and careful planning. Choosing different factors leads to diversity in data layers, consequently the attempts to find adequate solutions and make correct decisions directs the decision makers to apply systems which not only have high accuracy but also are fast and easy to be used in operations. The object of the current study was to determine the environmental Shiraz landfill waste by using a fuzzy multicriteria decision analysis, hierarchical analysis, Geographic Information Systems (GIS), techniques was done using software Expert Choice. In this study, using data from the legal limits of the city, away from roads, airports, land use, capability land, artifact effects (rural, urban facilities and equipment, mining), fault, the physical development of the city, surface water, wind direction, population density, Soil, Hypsometric (height floor), slope, aspect, vegetation, land types, geological information etc. Combining data from different models and maps based on fuzzy logic to combine these data and models and Georefrence with satellite images in a region with radius 19 kilo-meters with 272 hectares in the north, which has limited capacity to accept the weight of tons of waste per day for 15 years may have been switching places.
