• A novel application of BWM-GIS-FAHP-GT has been utilized for landfill site selection. • Just 2.47% area of the Guilan province was selected as the "most suitable region" location. • Game theory was used successfully to find the best location from the authorities' point of views. • The fuzzy AHP was used to calculate the payoffs of players in the game. The novel application of a new hybrid method of Geographic Information System (GIS), Multi-Criteria Decision-Making (MCDM) and game theory has been investigated for landfill site selection in Guilan province, which has a temperate and humid climate. The data utilized in the study were mostly obtained from satellite images and local organizations. Three main categories of environmental, social and economic impacts comprising fourteen criteria, based on the sustainability of a landfill location, were analyzed. Criteria weightings were obtained using the Best-Worst Method (BWM) and then a suitability map was produced by GIS analysis. Moreover, the restrictions for an airport (8 km), historical and touristic areas (3 km) and the border of the province (2 km) were applied. The result of the GIS was then analyzed using game theory (GT) in order to study the interactions of decision makers. In order to apply the new criteria for the game theory, a fuzzy analytical hierarchy process (FAHP) was used to find the weightings of five new criteria, which have been used for players' payoffs. The most optimum location (site A 1) was investigated and found to be near rural areas of the study region which could cause inevitable harm to the adjacent communities. Furthermore, only 2.47% and 0.78% areas of the Guilan province is in the "most suitable region" and "suitable region" classes, respectively; which raises the awareness of finding a sustainable approach for saving the environment rather than the landfilling.

A new hybrid method of utilizing Evidential Reasoning (ER) approach and Geographic Information System (GIS) was applied to find the optimum location of a Combined Heat and Power (CHP) incineration plant in Guilan province. According to guidelines and prevailing conditions, thirteen criteria were analyzed and divided to three main sections of environmental, social and economic categories. Most of the data in the study were obtained from local organizations and satellite images. To weight the criteria, evidential reasoning was applied to aggregate the decision-makers' opinions, and to find the potential sites; spatial analysis was done through the GIS. The result of suitability analysis indicates that about 0.07 % of total area of Guilan province is "the most suitable" region for the incineration plant and 0.05 %, 0.07 %, 2.77%, and 97.04 % are in the class of "suitable", "relatively suitable", "least suitable" and "limited". The areas with an area of larger than 40,000 m2 which is the necessary area for a 9 MW incineration plant were classified as alternatives for incineration CHP plant locations (A 1 -A 7). All the locations were investigated to be near rural areas, which might bring inevitable harm to the adjacent communities. Also, the low amount of "most suitable region" and "suitable region" foster a sense of concerns, which should be addressed by applying a sustainable approach for preserving the environment. The techno-economic analysis presented in this study indicates that the project is not economically beneficial at all. [ABSTRACT FROM AUTHOR]
