Abstract
In a city, there are different sectors in operation and each sector also plays a role in the production of municipal waste, which draws attention to waste management methods. In the present study, a model to identify the factors affecting the production of waste in Bushehr has been explained.
Methodology: The main dimensions of the model are taken from the review of the theoretical literature in the field of urban waste management. Dynamic systems approach has also been used to identify urban waste management strategies, which is the main purpose of this study. In this research, we have tried to first identify the factors affecting the production of municipal waste and model it with the help of dynamic systems. Dynamic systems can include the complexity, nonlinearity, and cyclic feedback structures that are inherent in physical and non-physical systems. Therefore, they have the advantages of using the simulation method over the analysis methods. In the next step, the internal and external factors of the organization in the field of urban waste management and by referring to the SWOT analysis method, urban waste management strategies in Bushehr were performed.
Findings: The results of the SWOT method showed that the vulnerability threshold of urban waste management in Bushehr is very high and it is necessary to provide appropriate policies to address weaknesses and threats using strengths and opportunities. In the next step, Mikhailov's nonlinear method was used to rank the four strategies. The results of using this approach show that among SO strategies, the strategy of increasing awareness and changing citizens' attitudes towards proper waste management is in the first place. Among ST strategies, culturing for the use of recyclable containers weighing 0.51 is in the first place. Employing knowledgeable people for proper waste segregation and disposal among WT strategies, with a weight of 0.57 was ranked first, and finally the strategy of encouraging the private sector to invest with a weight equivalent to 0.43 among WO strategies Ranked first.
Originality/Value: The current research is innovative by focusing on combining fuzzy logic with dynamic systems modeling approach and Delphi method.
