This study optimized Tehran's Solid Waste Management System (SWMS) using a linear programming model. The model reduced the number of transfer stations and processing units, improving efficiency.
Area of Science:
- Urban Management
- Environmental Engineering
- Operations Research
Background:
- Solid Waste Management (SWM) is crucial for urban areas, requiring systematic approaches to address environmental concerns.
- Effective SWM is legally recognized as a vital component of urban infrastructure.
- This research focuses on developing an integrated SWM model for metropolises.
Purpose of the Study:
- To design and apply a linear mathematical programming model for integrated Solid Waste Management.
- To optimize the Solid Waste Management System (SWMS) in Tehran.
- To identify potential reductions in infrastructure for improved SWM.
Main Methods:
- A novel linear programming model was developed for integrated SWM.
- The model was implemented using Lingo software.
- Data from Tehran's SWMS, including 22 municipal regions, 11 transfer stations, and 10 processing units, were utilized.
Main Results:
- Application of the linear programming model determined an optimal configuration for Tehran's SWMS.
- The model's execution led to a reduction in the required number of transfer stations from 11 to 10.
- The number of processing units was optimized, decreasing from 10 to 6.
Conclusions:
- The proposed linear programming model offers an effective method for enhancing urban SWMS.
- The model facilitates infrastructure optimization by reducing the number of transfer stations and processing units.
- This approach provides a viable alternative for improving the efficiency and sustainability of metropolitan SWM.
