An evaluation framework for developing green infrastructure by using a new hybrid multiple attribute decision-making model for promoting environmental sustainability

With the expansion of urbanization caused by the growth of population and industrial activities, the urban/city and suburban areas are facing a variety of environmental threats. Although more research and urban policy has advocated and practiced the development of green infrastructure (GI) to support urban sustainable environment, the evaluation framework for the development of GI for promoting environmental sustainability is still insufficient. Moreover, the Analytic Hierarchy Process (AHP) commonly applied in published literature, makes an unrealistic assumption of independent relationships among dimensions/criteria in decision making for satisfying the real-world problem. Therefore, the purpose of this study is to construct the evaluation framework, including four dimensions and related ten criteria, using a new hybrid-modified multiple attribute decision-making (MADM) model for developing and improving the GI for promoting environmental sustainability. This MADM model is combined with three different methodologies of MADM, including the Decision-Making Trial and Evaluation Laboratory (DEMATEL) for constructing the influential network relation map (INRM) to explore the complex influential inter-relationships and DEMATEL based on Analytic Network Process (DANP) for determining the influential weights with the VIse Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) for evaluating and presenting improvement strategies for six different GIs. The empirical study indicates that DEMATEL and DANP Results suggest that decision-makers should pay more attention to the improvement of Design (D₄) and Materials (D₂) in terms of dimensions when utilizing the GI to promote environmental sustainability. Because these dimensions are enhanced, Species (D₁) and Energy (D₃) will be improved in synchronization. From the perspective of criteria, five are key core criteria and need to be focused on first: increasing the green coverage rate (B₉), utilizing sustainable materials (B₄), using ecological engineering (B₈), shaping species biodiversity (B₁), and reducing energy consumption (B₅). Modified VIKOR reveals that “grass swales” are a comparatively better choice among six GIs for promoting environmental sustainability toward achieving the aspiration level. Therefore, this MADM model is beneficial to provide a more convincing assessment framework and improvement strategies for the development of GI for promoting environmental sustainability. As a result, these modified MADM models can be shown more conveniently and reasonably than traditional methods such as traditional AHP or ANP method.

Exploring heritage tourism performance improvement for making sustainable development strategies using the hybrid-modified MADM model

Industrial heritage tourism has become increasingly popular in recent years. However, strategies for improving the industrial heritage tourism development-related performances are still an underdeveloped research topic academically. Therefore, this study’s purpose is to explore the feasibility performance-improving strategies using a hybrid-modified multiple attribute decision-making (MADM) based on the DEMATEL technique in constructing the influential network relation map (INRM) and in determining the influential weights of DANP. Then, the modified VIKOR method is combined with the influential weights of DANP, performance gaps were identified, and then the most effective strategies for improving tourism development-related performance at industrial heritage sites can be generated using INRM. Finally, an empirical real case study of a rehabilitated gold-mining site of Taiwan is used to demonstrate the effectiveness of the hybrid-modified MADM model. According to the results, the decision-makers should highly prioritize improving high-priority criteria such as ‘social usefulness’, ‘resource integration’, ‘destination policy and development’, ‘economic development’, ‘cultural links’, ‘cultural learning’, and ‘natural landscape resources’ in advance to successfully achieving the aspired performance levels. Additionally, this study suggests meaningful industrial heritage tourism performance improvement strategies that have been rehabilitated throughout the world.     

An operational method to supporting siting decisions for sustainable rural second home planning in ecotourism sites

Due to inadequate environmental assessments, many sustainable tourism destinations have not contributed to both conservation and development as expected. This paper describes an operational spatial planning method to evaluate the suitability of an ecotourism site. As using the multi-attribute decision-making (MADM) based on the understanding of all possible aspects and implications of the existing regional planning, this work presents a process to siting second home countryside in the study area, La Vera County, Spain. Accordingly, this study explores the criteria using the analytical hierarchy process (AHP) with the primary screening and supporting opportunities of environmental conservation and economic growth as well. To reach a consensus criteria weight, a field survey to local residents and group discussion with a panel of experts were conducted for an analytical procedure, making them more objective. Then, it evaluated the suitability of the study area in order to optimally site a rural second home based on the previous constraints and criteria with the aid of the ordered weighted averaging (OWA) operator weighing functions with constant value of orness and maximum entropy. The assessment results provide a new empirical approach and valuable management tool to evaluate the existing infrastructure and environment and to predict their future improvements that can be reapplied to other destinations. These strongly emphasize benefits to the local community and effective ecotourism with its integration. Particularly, this model analysis proposes a method to demonstrate the participatory attitude of local residents in the sustainable planning assessment.     

Schemes for enhancing Taiwanese cruise PAK relationships using the hybrid MADM model

Because of the emerging cruise travel market, major Taiwanese travel agencies have promptly formed PAK to distribute cruise sales nationwide. However, few studies have discussed this issue or proposed empirical schemes to help enhance relations inter-alliances. The purpose of this study is to address this problem within the theoretical framework of trust-commitment theory. The method of hybrid MADM (multiple attribute decision-making) is used to manage multi-variant problem and produce optimal enhancing models. The result shows that Trust and Commitment mediate the relation, as found in previous studies, but unveils that Antecedents can also directly influence Relational outcomes, such as from Opportunistic behavior to Propensity to leave. Notably, Trust and Commitment play the leading roles to reach the aspired relation. The findings are integrated into a useful scheme index for decision-makers to enforce the on-going relational exchange to reach the common goal of PAK.
