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.

这项研究有助于评估越南沿海和海洋城市的可持续固体废物管理，因为先前的研究缺乏制定一套分级结构的措施。沿海和海洋旅游城市是旅游业中规模最大，增长最快的部分。在缺乏固体废物管理能力的情况下，城市基础设施正在建设中，并在衡量可持续固体废物管理方面造成了差距。这项研究采用定性技术和定量方法来扩展文献。探索性因素分析用于测试所提出的层次框架的有效性和可靠性。一个模糊的综合评价和一个决策试验与评价实验室被用来评价城市中可持续的固体废物管理。在六个方面构建了一套考虑经济效益，环境评估和社会影响的标准：资金和支出，旅游活动，政策和法律框架，环境共同创造，利益相关者的参与和社区意识。结果揭示了各方面之间的因果关系，利益相关者的参与，旅游活动以及政策和法律框架是实现可持续发展绩效的因果属性。人们还发现，土建杂物，游客流，政治领导的支持，费用分摊和共同战略的采用以及技术合作是成功的标准，可为从业人员和社区提供实用指南。需要更加重视沿海和海洋环境，
