Although wetland environmental protection plans are synonymous with wetland management and erosion control plans, the public perceptions of such plans often focus on their impact on the human ...enjoyment of wetland areas. These plans are affected by many interrelated influence factors, such as human welfare, property, safety, management, operations, maintenance, ecology, environment, artificial structures, climate control, and sustainable development. The purpose of this paper is to probe how to use qualitative and quantitative measurements of wetland environments to create plan indexes using criteria/attributes as well as how to help these indexes for achieving the aspiration levels in each criterion/attribute. Previous studies that attempted to measure environmental evaluations and plans have assumed that these criteria are independent, but this assumption does not hold in real-world applications of real problems. Therefore, in this proof-of-concept study, using an empirical exam among various attributes and to measure and evaluate the real conditions for improving the wetland environmental problems. A DEMATEL technique can be used to construct the INRM, the basic concept of an ANP was modified to determine the influential weights of criteria/dimensions in our research alternative, called DANP (DEMATEL-based ANP). Then we can construct a decision-making model via a hybrid modified VIKOR method to improve wetlands environmental management manager strategy formulation in performance evaluation toward for achieving the aspiration level. Using these techniques, a proposed model appeared, which can be used to explain interdependence and feedback problems. Based on the final results, we can also propose a gap improvement in the development of a sustainable development plan for the environment while taking comfort and safety into account to improve standards and achieve human welfare expectations.
•We have developed a comprehensive model for achieving sustainable wetland environmental protection.•This new approach can provide a gap for sustainable development.•The sustainability plan takes into account the comfort and safety that humans expect.•Reducing flooding is a key goal for sustainable wetland development.•The method results are very accurate and represents other methods.
Mobile payment (MP) is a key tool for establishing a cashless society. To comprehensively examine the critical factors (CFs) that influence the introduction of MP tools by microretailers (MRs) in ...Taiwan, this study employed the technology–organization–environment model as a theoretical basis. Two multicriteria decision-making tools (i.e., the analytic network process and Vlse Kriterijumska Optimizacija Kompromisno Resenje concept of acceptable advantage) were combined to objectively identify the CFs influencing MRs’ introduction of MP tools. The results indicate that technology is more essential than organization and environment, and the eight identified CFs are security/trust, compatibility, usability, stability, complexity, organizational scale, government support, and information maturity. These CFs and the hybrid method form the basis for the findings and academic contributions of this study. The results serve as incisive and practical guidelines that can help MRs to introduce MP tools, encourage MP use by consumers, and promote the establishment of a cashless society.
This study aims to extend classic VIKOR technique for multicriteria decision-making (MCDM) problems within Pythagorean fuzzy (PF) scenario. First, judgments from decision makers (DMs) are expressed ...by PF sets that can describe more uncertain and ambiguous information than available fuzzy sets. Second, PF point operators are applied to denote the risk preference of the DM who may express an attitude toward an emerging science and technology. Third, a new generalized distance measurement formula considering all the characteristics of PF sets is proposed, and some attractive properties of distance measure, which outperforms available distance measures, are proved. Fourth, the novel generalized distance measure is employed to relative distance to identify the optimum and worst PF values and then employed in

Due to the occurrence of several recent threats, such as, from an international perspective, SARS, the 9/11 terrorist attack, increases in the price of oil, depressions in the economy, and, from a ...domestic perspective, increasing interaction with China, joining the WTO, low railway prices, and high-speed rail development, resulting in passenger rate dropping drastically, an increasing number of Taiwanese airlines have been facing deficits or closing down in recent years. Therefore, long-term strategies for gaining a competitive advantage are now starting to focus on innovation rather than cost reduction. Although attention to the importance of innovation is rising, there are few studies today that provide airlines with a clear and precise way to successfully conduct innovation operations. The aim of this study is to solve this dilemma by constructing a novel aviatic innovation system (AIS). In this paper, a hybrid fuzzy multiple criteria decision-making (MCDM) model based on a fuzzy analytical hierarchical process (FAHP) and a VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is adopted to complete the construction of the AIS. The value of the AIS is to provide Taiwanese airlines with innovation-oriented techniques for future strategy development. We believe that the AIS can contribute to the survival of Taiwanese airlines in the near future.
► We weight the performance indices based on the official performance evaluation structure of TWAEA. ► We apply a hybrid multiple-criteria decision-making (MCDM) model. ► We also compare the official ...rankings of the 12 private universities with our results. ► We endeavor to help universities optimize their performances with efficiency.
The aims of this study are to weight the performance evaluation indices for higher education based on the official performance evaluation structure developed by the Taiwan Assessment and Evaluation Association (TWAEA) and to rank 12 private universities listed by the Ministry of Education as a case study. We apply a hybrid multiple-criteria decision-making (MCDM) model to accomplish these objectives. Specifically, we utilize the analytic hierarchy process (AHP) to accomplish the first aim, but we adopt the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method for the second aim by utilizing the AHP outcome. We also compare the official rankings of the 12 private universities with our ranking of the same universities. Our study endeavors to help universities optimize their performances with efficiency. In addition, the results of this study could provide a reference point for other universities and related educational institutions in their efforts to conduct evaluations, improve their performances and form educational policies.
This study proposes a framework that contains four dimensions (environment, economy, socio-cultural, and technology) and nine relevant criteria for evaluating smart office buildings through a hybrid ...multi-attribute decision-making (MADM) model. A Taiwanese case study of the silver-level label office building is evaluated within this study. Using the Decision making trial and evaluation laboratory (DEMATEL) (di + ri = central degree, di-ri = cause degree) this study reveals that the core dimension for evaluating smart office buildings more sustainable is the technological dimension (D4) (34.007, 0.967), followed by the economic dimension (D2) (38.725, 0.175) and the socio-cultural dimension (D3) (37.743, 0.047); improvements to these three dimensions drives the environmental dimension (D1) (48.694, −1.190). In terms of the criteria, automation (C8) (19.328, 0.587), interactivity (C9) (14.679, 0.380), waste management (C3) (13.884, 0.300), architectural innovation (C7) (18.882, 0.226) and affordability (C4) (19.070, 0.201) are five critical criteria. Although the performance of the Taiwanese case study is, in terms of its sustainability, acceptable (Total performance = 9.530 and the gap ratio to aspiration level = 0.046) based on the modified VlseKriterjumska Optimizacija i Kompromisno Resenje (VIKOR), there is still room for further improvements to be made in terms of sustainability.

In Wireless Sensor Networks (WSNs), resource depletion attacks that focusses on the compromization of routing protocol layer is identified to facilitate a major influence over the network. These ...resource depletion attacks drain the batter power of the sensor nodes drastically with persistent network disruption. Several protocols were established for handling the impact of Denial of Service (DoS) attack, but majority of them was not able to handle it perfectly. In specific, thwarting resource depletion attack, a specific class of DoS attack was a herculean task. At this juncture, Multicriteria Decision Making Model (MCDM) is identified as the ideal candidate for evaluating the impact introduced by each energy depletion compromised sensor nodes towards the process of cooperation into the network. In this paper, A Pythagorean Fuzzy Sets-based VIKOR and TOPSIS-based multi-criteria decision-making model (PFSVT-MCDM) is proposed for counteracting with the impacts of resource depletion attacks to improve Quality of Service (QoS) in the network. This PFSVT-MCDM used the merits of Pythagorean Fuzzy Sets information for handling uncertainty and vagueness of information exchanged in the network during the process of data routing. It utilized VIKOR and TOPSIS for exploring the trust of each sensor nodes through the exploration of possible dimensions that aids in detecting resource depletion attacks. The experimental results of PFSVT-MCDM confirmed better throughput of 21.29%, enhanced packet delivery fraction of 22.38%, minimized energy consumptions 18.92%, and reduced end-to-end delay of 21.84%, compared to the comparative resource depletion attack thwarting strategies used for evaluation.
Electric vehicle charging station (EVCS) site selection occupies a prominent position in the development of the electric community to solve the hard problem of Electric Vehicle (EV) charging. ...However, two critical issues have not been solved by the existing research. Firstly, the scope of EVCS site selection only considers the whole city, which deviates from the actual situation. Secondly, the uncertainty and hesitation of decision information is not well expressed. To handle the above problems, this paper builds a comprehensive EVCS site selection decision framework for Residential Communities (EVCSRC) with triangular intuitionistic fuzzy numbers (TIFNs). First of all, the distinctive index system of EVCSRC site selection factors including economy, social, environment, planning and feature portrait of residential communities is established. Then, the TIFNs is utilized for decision makers (DMs) to express the indeterminate information. Furthermore, a fuzzy Vlsekriterijumska Optimizacija I Kompromisno Resenje (Fuzzy-VIKOR) is approach is utilized to rank the alternative EVCSRC sites. Finally, a case of Beijing is studied to demonstrate the validity of the proposed site selection framework. The result shows the EVCSRC site located at Sijiqing community in Haidian district should be selected as the optimal site. This paper presents a feasible and easy-to-use decision-making framework for investors.
Energy consumption is increasing in many regions and governments are compelled to develop and implement strategic energy investments. The limited amount of fossil fuels and their negative ...environmental impact are a major drive for countries to use more renewable energy. There has been a rapid increase in renewable energy investments at the beginning of the twenty-first century. However, compared to traditional fossil fuels, renewable energy entails more uncertainties, which increases the difficulty in making long-term, strategic investments. These uncertainties led to the need to apply different and effective methods and approaches for renewable energy investments. Recently, Multi-Criteria Decision-Making methods are used frequently to develop new and different solution methods in the solution of ranking energy systems. This study uses Multi-Criteria Decision-Making methods for strategic renewable energy investment. This study aims to provide a model to assist decision-makers in renewable energy alternative selections by using two popular Multi-Criteria Decision-Making methods, Analytic Hierarchy Process and VIseKriterijumska Optimizacija I Kompromisno Resenje. Analytic Hierarchy Process was used to evaluate the weights of the criteria by pair-wise comparison. Then, the VIseKriterijumska Optimizacija I Kompromisno Resenje method was used as the second part of the study to rank the alternatives by their weights of importance. It is observed that each renewable energy alternatives have different priorities and performance values under each criterion in the city of Chicago. Then, it is concluded that energy efficiency has the highest ranking as the best performing alternative in Chicago.
