• This study proposes a set of attributes to access sustainable solid waste management performance in Vietnam. • Fuzzy DEMATEL is to handle the interrelationships and ANP is to build the hierarchical structure to acquire the aspects and criteria weights. • Sustainable solid waste management requires the leadership of politics to drive stakeholders' participations and social impacts. • Population growth and migration, institutional settings, waste recycling and energy recovery, households, and private contractors are critical for improvement. This study contributes to building a valid hierarchical sustainable solid waste management (SSWM) attribute set with qualitative information, which is a complicated and ambiguous problem with uncertainties. Few studies have provided qualitative information and have addressed the interrelationships and interdependencies among the hierarchical SSWM attributes. SSWM has recently become a difficult problem to solve due to urbanization, inequality, and economic growth. This study aims to propose an SSWM attribute set and identify a causal model through linguistic preferences by using a fuzzy decision-making trial and evaluation laboratory approach to simultaneously handle the uncertainty and the interrelationships. The analytic network process is used to develop the hierarchical structure to weigh the aspects and criteria. Qualitative information is transformed into crisp and comparable values to examine the causal relationships between attributes and confirm the consistency between the theoretical structure and industry phenomena. The results indicate that policy and regulations, stakeholder participation, and social impacts play essential roles in these causal interrelationships. Political leadership in SSWM is required to drive stakeholder participation and achieve social impacts. Population growth and migration, institutional settings, waste recycling and energy recovery, households, and private contractors are the main aspects involved in improving SSWM in Vietnam.

• There is gap in measuring sustainable solid waste management in coastal and marine tourism cities. • Fuzzy synthetic evaluation and decision-making trial and evaluation laboratory are proposed. • A hierarchical framework is constructed to examine the causal interrelationship among attributes. • Stakeholder participation, tourism activities, and policy and legal framework are important to archive sustainability. • Civil construction debris, tourist flow and political leadership support are as practical guidelines. This study contributes to assess the sustainable solid-waste management of coastal and marine cities in Vietnam due to prior studies are lacking to develop a set of measures in hierarchical structure. Coastal and marine tourism cities are the largest and fastest growing segment of the tourism industry. City infrastructures are being developed in the absence of a solid-waste management capacity and create a gap in the measurement of sustainable solid-waste management. This study employs both qualitative techniques and quantitative measures to extend the literature. An exploratory factor analysis is applied to test the proposed hierarchical framework's validity and reliability. A fuzzy synthetic evaluation and a decision-making trial and evaluation laboratory are used to evaluate sustainable solid-waste management in the cities. A set of criteria that consider the economic benefit, environment assessment and social impact are constructed on six aspects: funding and expenditures, tourism activities, the policy and legal framework, environmental co-creation, stakeholder participation and community awareness. The result reveals the causal interrelationships among the aspects and that stakeholder participation, tourism activities, and the policy and legal framework are the causal attributes for achieving sustainability performance. Civil construction debris, the tourist flow, the support of political leadership, cost-sharing and mutual strategy adoption, and technical cooperation are also found to be success criteria that contribute as practical guidelines for practitioners and communities. More emphasis needs to be placed on coastal and marine environments, and doing so has the highest priority value and contributes to raising awareness of issues in the development process.

Resources and expertise for controlling processes are inadequate due to municipal solid waste management (MSWM) capability limitations in Vietnam. The resource-based view (RBV) needs to be considered in the assessment of municipal solid waste management. Nevertheless, in practice, various attributes of municipal solid waste management are not considered in the sustainable performance of cities. Hence, this study applied exploratory factor analysis (EFA) to confirm the validity and reliability of these attributes and construct a hierarchical structure. Fuzzy set theory was used to convert the linguistic preferences into crisp values and the decision-making trial and evaluation laboratory (DEMATEL) method was used to assess the causal interrelationships among the attributes. The analytic network process (ANP) was adopted to construct the hierarchical framework, and fuzzy importance - performance analysis (IPA) was used to enhance our understanding of the gap between importance and performance. The results show that the efficiency and effectiveness of cities' waste management systems depend on the capability based on utilizing economic efficiency and technology advantages to foster social mobilization and environmental integrity. Practitioners should consider new data acquisition and communication technologies, the circular economy, technical capabilities, and organizational/leadership capabilities in their decision making to promote sustainable performance. To develop sustainable MSWM, suitable strategic solutions based on the resources and strengths of each city should be developed that consider formal, informal and small-scale sectors. • The resource-based view is applied to analyze the municipal solid waste management for improving the sustainable advantages. • Hybrid method is used to confirm the attributes' validity and reliability and construct a hierarchical structure. • Cities depend on the capability based on utilizing economic efficiency and technology advantages. • Practitioner has to involve new data acquisition and circular economy to promote sustainable performance.

This study aims to explore integrated solid waste management hierarchical interrelationships using a sustainable balance scorecard approach. The proposed analysis using the fuzzy Delphi method to exclude invalid attributes, interpretive structural modeling to arrange attributes into an extensive hierarchical model, and using a fuzzy decision-making trial-and-evaluation laboratory to examine the causal interrelationships among attributes. The solid waste management systems in Vietnam are generally inefficient due to a lack of proper administrative oversight, infrastructure, and adequate resource utilization. Integrated solid waste management is an important provision in public service systems. There is a need to propose and evaluate better management approaches to enhance waste process activities and increase sustainable performance. Collected qualitative information is converted into a crisp value for the evaluation process, and the qualitative data stem from the operations. This study measures 6 aspects and 24 criteria. The results showed that financial investment, stakeholder involvement, and innovation capacity are decisive causal aspects in which stakeholder involvement and innovation capacity are interrelated. The cost efficiency, stakeholder collaboration, flexibility/adaptability to environmental changes, availability of local technical skills, and knowledge acquisition and communication technologies are identified as the linkage criteria that present the highest driving and dependence powers to help decision makers achieve better operational performance. • This study aims to explore ISWM using a sustainable balance scorecard. • Fuzzy Delphi method is to exclude the invalid attributes. • ISM arranges attributes into an extensive ISWM hierarchical model. • Fuzzy DEMATEL presents the causal interrelationships. • The financial investment and stakeholder involvement capacity are the decisive attributes.

There are existing inadequate and ineffective practices that are not only common in Vietnam but also explicit in each municipal area. This study compares the municipal solid waste management attributes of cities in Vietnam under uncertainty. The uncertainties include the interrelationships among the attributes, linguistic preferences and qualitative information on the attributes. This study applies exploratory factor analysis to test the validity and reliability of the proposed attributes. Fuzzy set theory is used to translate the linguistic references into the qualitative attributes of municipal solid waste management. The decision-making trial and evaluation laboratory is used to address the interrelationships among the attributes. This study identifies the causal interrelationships among attributes using qualitative information, and a set of 14 attributes is defined and found to be valid and reliable for measurement. The results show that technical integration and social acceptability are the aspects that drive municipal solid waste management. Treatment innovations, safety and health, economic benefits, and technology functionality and appropriateness are determined to be the linkage criteria. The distinctions between cities are identified, Hanoi focuses on the institutional and organizational administration framework, whereas resource efficiency is an aspect of specific concern in Danang, and Ho Chi Minh City prioritized financial and operational requirements and facilities and infrastructure requirements. The implications for theory and practice are discussed. [ABSTRACT FROM AUTHOR]
