Enhancing Urban Solid Waste Management Through an Integrated Geographic Information System and Multicriteria Decision Analysis: A Case Study in Postwar Reconstruction

This chapter developed a geographic information system (GIS) model and applied spatial analysis techniques to determine the most suitable location for municipal solid waste transfer station within the city of Vinnytsia, Ukraine. The absence of such a station within the city’s sanitation infrastructure gives rise to numerous challenges, leading to an overall decreased efficiency in waste management. With the rising costs associated with solid waste management, the importance of optimizing processes during the transportation stage has become increasingly evident. This issue is particularly significant in rapidly growing urban areas. Given the intricate hierarchical nature of waste management systems, the process of site selection requires a thorough examination of various alternative solutions and assessment criteria. Drawing on the conditions of the study area, a thorough look at the relevant factors and established criteria weights was examined using multicriteria decision analysis. A hierarchical model was then constructed to address the challenge of determining the optimal site for a waste transfer station in the city using spatial data. The creation of suitability maps for the geographical area was undertaken based on a range of criteria. These criteria were assessed on a scale from 1 (i.e., lowest suitability) to 5 (i.e., highest suitability), utilizing spatial information technologies. The potential sites for consideration were categorized using the best-worst method: “optimal,” “favorable,” and “unsuitable.” Optimal sites represent the most advantageous choices, while favorable sites could serve as backup options for potential candidates. This information possesses practical value for individuals responsible for making managerial decisions in the context of municipal solid waste management in urban areas marked by significant urbanization. Moreover, the model serves as a demonstrative example of infrastructure development and nation building, an important consideration for the country in the postwar reconstruction period.
