Suitable Site Priority to Establish of Urban Nuisance Industries Using Multi-Criteria Decision Analysis and Mathematical Programming Models

Rapid and heterogeneous urban growth and also imbalance between urban environment and urbanism culture have caused many problems. Some of these problems that caused by occupations and urban industries affected on urban fabric, social stratification and citizen life directly and indirectly. In order to protect human health and urban environment all of the disturbing industries should be transmitted on suitable sites. In this regard, choosing the best site in the urban landscape is a very important issue. Indeed, this study is done to select suitable site for Azna nuisance industries. 

In this research, after standardizing the layers and preparing the constraint maps, the weighted linear composition method was used to combine them. In order to determine the most suitable area, the competency approach of land areas was used and all patches with values higher than 200 and further than 5 hectares were identified. Finally, 15 zones were obtained, which were prioritized using mathematical programming and 5 factors of distance from the city center, road, nearest village, area of zones and average value of competencies.

The results showed that the 10th and 2nd patches are most suitable site to establish urban nuisance industries respectively.

Overall, it can be concluded that simply determining the appropriate zones is not enough to transfer industries, but determining the best zone and also prioritizing other zones is of special importance that can help managers in choosing the most appropriate zone.
