Analytical Hierarchy Process-Based Decision Making for Sustainable MSW Management Systems in Small and Medium Cities

Municipal solid waste management is one of the key challenges of environmental, economic and social importance. It is a global problem regardless of economic development level and political orientation, and also applies to a country such as Belarus. There is a lack of studies considering the local aspects of waste management in Belarus, therefore the research is actual. The study aims to formulate the recommendations on the conceptual modelling of the MSW management system in Belarus. The research methods are based on the complex systems approach. The study provides a review of the actual concepts on MSW management, including its general principles, hierarchy and methods, analysis of the current state of MSW management system in Belarus, and recommendations on modeling the MSW management system covering the local and regional aspects in Belarus. The suggestions on formulating the MSW management system involve organizational, economic, technical and informational bases as well as considering the local and regional specifics. The results indicate the following: (1) the current MSW management system in Belarus does not move the country towards a circular economy, requiring an update of the existing waste management strategy; (2) sustainable waste management demands an integrated approach in order to support waste recycling into a manufacturing resource within circular economy; (3) two main approaches to solve the problem of waste management in rural communities have been identified— an economic approach implies the minimization of waste generation while a technological approach comprises the development of mini-solutions for waste recycling at the places of waste generation. The research results contribute to the increased interest in the issue of MSW management in Belarus, and can be a useful tool for improving the planning strategies considering the local and regional context.

MSW Management to Zero Waste: Challenges and Perspectives in Belarus

“…The AHP involves simple theories but is practical [24]; therefore, it has been widely used by various research institutions since its inception, particularly for planning, prediction, judgment, resource application and trial investment portfolios. In general, the AHP begins with a description of problems [25], the identification of primary factors, the establishment of hierarchical relationships, and the prioritization of decision attributes at each level, using pairwise comparisons and ratio scale. After priorities are assigned, pairwise matrices are established, eigenvalues and eigenvectors of the matrices are calculated, and the weight values of all attributes are derived.…”

Establishing Merger Feasibility Simulation Model Based on Multiple-Criteria Decision-Making Method: Case Study of Taiwan’s Property Management Industry

Chien

2021

The purpose of this study is to propose a feasible operational evaluation model for property mergers. It is expected that through the merger of enterprises, the comprehensive improvement of business management and the promotion of logistics supply resources will be effectively promoted, so that enterprises can effectively reduce operating costs and achieve maximum profits. This study uses the modified Delphi method and analytic hierarchy process method to find out the key factors of the common dilemmas in Taiwan’s property management companies, and the weight of their impact on the operation. Finally, we use the expected utility theory to develop a valuation model for whether the property is suitable for integration, and to evaluate this, the result is used as a reference indicator for merger operations. After 30 years of vigorous development in Taiwan’s property management companies, due to fierce market competition, most of the companies have reduced their profitability in the face of common dilemmas. The study found that the merger model should be accurately evaluated by the evaluation model. The sharing of logistics resources can indeed bring about the benefits of investment and marketing to the merger, and improve the profitability of the company. At the time of writing, there is no research on such a combined analysis of the property management industry in Taiwan. This research method uses multiple decision analysis theory and utility theory to develop a decision-making model that is suitable for consolidation. It can also be applied to the assessment of mergers in other fields, such as the clean service industry, real estate brokerage and other industry merger assessments. This is also the biggest contribution of this research paper.

“…In Thailand, a small city considered the criteria of environmental (with 3 indicators), economic (3), social (2), and technical (4) dimensions when conducting the assessment of the solid waste management system. The results showed that the environmental aspect is considered as the most important [24]. In addition, to develop a set of criteria for sustainable solid waste management in Central Java Province, Indonesia, the authors selected 12 criteria and 3 alternative treatment solutions (composting, recycling, and sanitary landfill) [25].…”

“…In addition, several methods have been applied for selecting optimal alternative treatment solutions. The Analytic Hierarchy Process (AHP) method was used to determine weights of criteria and find alternative treatment solutions [24,[27][28][29][30], whereas the TOPSIS method was adopted to propose a suitable waste treatment in Lahore [31]. The AHP method was also incorporated into the Delphi method to identify a proper set of criteria and technologies to treat MSW that are more economical and environmentally sound [32].…”

Development of Sustainability Assessment Criteria in Selection of Municipal Solid Waste Treatment Technology in Developing Countries: A Case of Ho Chi Minh City, Vietnam

Anh

Dinh³

et al. 2023

Municipal solid waste (MSW) management is a significant problem for developing countries due to lack of sufficient infrastructure, poor management capacity, and low level of waste treatment technology. This study proposes three main groups of criteria, i.e., social, economic, and environmental, that can be used as an effective tool to assess the sustainability of MSW treatment technologies, considering Ho Chi Minh City, Vietnam as a case study. The sustainability assessment criteria consist of a list of indicators which consider potential waste treatment plants. The indicators and technologies then undertake a selection process from identifying assessment goals and key aspects to data collection and consultation of experts. The findings from the previous phase will be used to select the most preferred waste technology through AHP and normalization approaches. As a result, 12 selected indicators are as follows: investment cost, treatment cost, operation and maintenance costs, revenue/benefits, job creation, community consensus, support policy, community health, air pollution, water pollution, greenhouse gas emissions, and land quota. Among three MSW facilities selected, i.e., landfill, compost, and waste-to-energy incineration, waste-to-energy is determined as the best alternative solution for Ho Chi Minh City in a given context of approximate 70% of landfilling being applied. The selection process and indicators found can guide decision-makers and policy on selecting MSW treatment technologies in developing countries. Additionally, Ho Chi Minh City’s governors benefit from finding the most appropriate waste technology. A technology adoption roadmap and its implementation plan should be thought thoroughly to address challenges in MSW management in the city.
