Urban Land Use Allocation Using MCDMs and GIS, Case Study: Zanjan City

City Development and its direction is always a potential problem in urban planning. In modeling this phenomenon, variety of criteria are involved, directly and indirectly. So it is assumed as a complex Multi-Criteria Decision Making problem. There is a wide range of rigorous methodology to analyze these types of problems. TOPSIS method is an appropriate approach to deal with MCDMs. This model accounts for the distance between each solution with ideal solution. In this research, the most appropriate direction of Zanjan city deployment is investigated considering economic, environmental, physical and climatically parameters employing TOPSIS method. The results illustrate that the eastern and north-western spaces are more suitable to city development. In contrast, the southern and northern parts are not primarily suitable in this case. It is notably to mention that 15% of city development since 2005 has been accrued in inappropriate areas.
