With the rapid transformations of living environments, urban sustainable development has become an important global issue for urban growth and management. In order to effectively implement urban sustainable development, it is necessary to establish an operational action model based on its nature. This study first clarifies the core value of urban quality of life (QOL), and proposes the corresponding concept of Life–City. A variety of factors may affect the content of Life–City, and when assessing the objectives of sustainable development, there are uncertain properties and value judgments. Therefore, Life–City evaluation is a fuzzy multi-criteria decision analysis (FMCDA) problem. This study constructs the dimensions and the possible impact factors for urban QOL development. The fuzzy Delphi method (FDM) is employed to screen evaluation criteria and develop the overall evaluation framework. In order to effectively convert the subjective and perceptual issues in the framework into objective and quantitative processing, this study adopts the extent analysis method on fuzzy AHP (EAFAHP) to aggregate experts’ comments as empirical evaluation. The research results can convert the abstract concept of sustainability to the evaluation of Life–City specific operation, and serve as guidance for self-examination of current status and future policy development.

The paper developed a methodical approach to the evaluation and selection of strategic alternatives to businesses based on their prioritization using the tools of fuzzy multi-criteria analysis and fuzzy logic. This approach is based on the use of fuzzy Analytic Hierarchy Process (Fuzzy AHP) with a certain term, set for paired comparisons variants and corresponding triangular fuzzy numbers. Evaluation criteria are considered as fuzzy sets defined on universal sets of options (strategic alternatives) using membership functions. Membership functions of fuzzy sets are defined based on expert information on the pairwise comparisons of alternatives using the fuzzy Saaty scale. To ensure the consistency of expert estimates, it is proposed to use the Fuzzy Delphi method. To determine the importance of the evaluation criteria and to calculate fuzzy values priority strategic alternatives for these criteria using the procedure Fuzzy AHP method. The resulting weights of criteria are considered as an appropriate degree of concentration membership functions. The calculation of the integral value of the priority level of strategic alternatives is carried out based on the Bellman-Zade scheme known in the theory of decision-making. For practical implementation of the methodological approach in the Matlab computer system (Fuzzy Logic Toolbox package), a framework is developed, which contains four main blocks: a block of input of expert information on the relative superiority of criteria in pairwise comparison and strategic alternatives to these criteria, a block of calculating weights, criteria a block for calculating fuzzy values of the priority of strategic alternatives according to these criteria and a block for finding the intersection of the obtained fuzzy sets according to the Bellman-Zade scheme. Defuzzification of the obtained fuzzy values is carried out based on the CoA method (Center of Area method). This framework allows you to perform simulations depending on the input data obtained from experts. The developed methodological approach allows the top management of the enterprise to determine the priority of the developed strategies in the presence of only qualitative information on the relative superiority of evaluation criteria and strategic alternatives and expands the possibilities of classical methods of strategic choice.

With the widespread of blockchain technology, preserving the anonymity and confidentiality of transactions have become crucial. An enormous portion of blockchain research is dedicated to the design and development of privacy protocols but not much has been achieved for proper assessment of these solutions. To mitigate the gap, we have first comprehensively classified the existing solutions based on blockchain fundamental building blocks (i.e., smart contracts, cryptography, and hashing). Next, we investigated the evaluation criteria used for validating these techniques. The findings depict that the majority of privacy solutions are validated based on computing resources i.e., memory, time, storage, throughput, etc., only, which is not sufficient. Hence, we have additionally identified and presented various other factors that strengthen or weaken blockchain privacy. Based on those factors, we have formulated an evaluation framework to analyze the efficiency of blockchain privacy solutions. Further, we have introduced a concept of privacy precision that is a quantifiable measure to empirically assess privacy efficiency in blockchains. The calculation of privacy precision will be based on the effectiveness and strength of various privacy protecting attributes of a solution and the associated risks. Finally, we conclude the paper with some open research challenges and future directions. Our study can serve as a benchmark for empirical assessment of blockchain privacy.

This study presents a hybrid methodology for solving the serious game design evaluation in which evaluation criteria are based on meaningful learning, ARCS motivation, cognitive load, and flow theory (MACF) by rough set theory (RST) and experts’ selection. The purpose of this study tends to develop an evaluation model with RST based fuzzy Delphi-AHP-TOPSIS for MACF characteristics. Fuzzy Delphi method is utilized for selecting the evaluation criteria, Fuzzy AHP is used for analyzing the criteria structure and determining the evaluation weight of criteria, and Fuzzy TOPSIS is applied to determine the sequence of the evaluations. A real case is also used for evaluating the selection of MACF criteria design for four serious games, and both the practice and evaluation of the case could be explained. The results show that the playfulness (C24), skills (C22), attention (C11), and personalized (C35) are determined as the four most important criteria in the MACF selection process. And evaluation results of case study point out that Game 1 has the best score overall (Game 1 > Game 3 > Game 2 > Game 4). Finally, proposed evaluation framework tends to evaluate the effectiveness and the feasibility of the evaluation model and provide design criteria for relevant multimedia game design educators.

The influences of ecological protection redlines on urban sustainable development can significantly vary from place to place with distinct ecological functions and human activity interference. However, recent research lacks the evaluation of ecological functions and human activity interference in ecological protection redline areas near urban areas. This article presents an evaluation method consisting of two evaluation criteria systems: an ecological function evaluation criteria system based on conserving water resources and soil and maintaining biodiversity and a human activity interference evaluation criteria system based on the human activity impact index, population and road network density, and the intensity of tourism activity and livelihood sewage discharge. This evaluation method was verified in Zoige County, China, by using remote sensing data to evaluate ecological functions and human activity interference in the ecological redline area for an urban environment. This evaluation method is one of the preliminary studies of urban sustainable development planning, and the result could provide a basis for the formulation of urban sustainable development strategy.

Due to the unbalance between Asian and Western countries in terms of higher education development and pressure from global competition, universities in several East Asian countries have striven to become world-class universities (WCUs) by actively assessing themselves using various global ranking systems and subsequently investing in key performance indicators. Numerous scholars have suggested that for these East Asian catch-up universities (EACUs), independently improving the elements related to high-weight indicators could produce short-term increases in ranking performance; however, this approach is not conducive to sustainable development. In addition, little is currently understood regarding sustainable development strategies for developing EACUs into WCUs. This study proposes a systematic evaluation model for self-assessment and the creation of strategies to transform EACUs into sustainable WCUs. The fuzzy Delphi method was used to determine criteria for a new evaluation framework, and the decision-making trial and evaluation laboratory method was employed to construct the influential relationships among the criteria. Two cases were then selected to demonstrate the superiority of the model for creating sustainable development strategies for EACUs. This study provides a systematic perspective and a useful tool for decision-makers at EACUs to achieve sustainable development goals.

Since the adoption of the Sustainable Development Goals by the United Nations, sustainability has been a key priority for European governments. While previous studies have investigated the associations between indicators of sustainable development, few have directly considered a multidimensional approach to assess and compare the performance of regions in terms of sustainable development. As such, a comprehensive assessment of regional sustainable performance is thus still needed. In this paper, the concept of sustainability relies on the construction of six composite indices (environment and natural resources, energy transition, sustainable mobility, economic dynamism, social cohesion and solidarity, and governance and citizenship) with the aim to provide an evaluation framework for empirically comparing the performance of the 96 metropolitan French Departments. Each dimension is explored by spatial autocorrelation analysis and Hierarchical Ascending Classification (HAC) to classify French Departments providing five different regional profiles of sustainable development. The findings make it possible to identify the strengths and weaknesses of the departments in the implementation of sustainable development. This approach provides the bases for a systematic monitoring of sustainable development policies at the regional scale.
