Comparison of municipalities considering environmental sustainability via neutrosophic DEMATEL based TOPSIS

Considering the increasing risk of various events to the environment, environmental sustainability has taken much more attention both by the academics and practitioners than the other topics. Every organization has its own responsibilities. However, public institutions have a more important role, since they have direct effect on all the community considering environmental sustainability. At this point, the performance evaluation of the municipalities becomes important and enables an effective management by not only indicating the existing status of the municipalities but also revealing the gaps for improvement. Hence, regarding the importance of environmental sustainability and performance evaluation, this study firstly provides the environmental sustainability dimensions with related indicators and presents an integrated methodology based on Neutrosophic Decision Making Trial and Evaluation Laboratory (N-DEMATEL) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for the performance comparison of municipalities. Different from the classical DEMATEL, N-DEMATEL addresses the inherent ambiguity and indeterminacy of decision making process while revealing the importance of factors considering the interaction between them. Afterwards, TOPSIS is used to determine the rank of the municipalities. So as to show the applicability of the proposed methodology, an application is performed in the district municipalities of Istanbul Metropolitan Municipality.     

Evaluating the transformation of China's resource-based cities: An integrated sequential weight and TOPSIS approach

The transformation and development is an inevitable problem for resource-based cities (RBCs). In the process of transformation, cities in various cities, regions, resource types and development stages are having shown commonality and uniqueness. However, little work has been done on the horizontal comparison between RBCs. This paper evaluates the transformation level of 81 RBCs in China from 2006 to 2017 and investigates the transformation effect of cities in different regions, different dominant resources and different development stages. The comprehensive index system incorporating economy, society and environment is established by using the improved TOPSIS method. The results indicate that the transformation effects of most RBCs are between 0.400 and 0.800. Generally speaking, the transformation effects of four economic regions are on the rise, especially in the western region, with an increase of 17.626% from 2006 to 2015. The transformation effect of RBCs in the eastern region is the highest, while that in the northeast is the worst. Regeneration cities’ transformation effect is the best, reaching more than 0.70 in 2017. The transformation effect of growth cities is the worst, but the growth rate is the highest from 2006 to 2015. There is a rising trend of the transformation effects for oil-based cities and coal-based cities, while the transformation effects of iron-oriented cities and rare earth-oriented cities are not obvious.

调制方式的动态TOPSIS识别

提出了基于动态理想解法（TOPSIS）的调制识别方法，将各特征参数看成一个整体，对各个调制方式判别打分，根据得分高低来判定调制样式。该方法简单、方便，弥补了传统判决树法判决门限难于选取的缺点，同时克服了神经网络法训练时间长、对算法要求高的难题。仿真验证了所提方法的有效性，在信噪比10 dB以上时正确识别率接近100%。     

Assessment of CSR based supply chain performance system using an integrated fuzzy AHP-TOPSIS approach

The objective of this research was to identify Corporate Social Responsibility (CSR) criteria as well as propose and prioritise the alternatives to improve the supply chain performance system of an organisation. To meet the objective, firstly, CSR-based criteria, sub-criteria and alternatives were identified based on the literature review and discussion with the field experts, taken from automobile industries located at the Delhi region of India. Then, kappa statistics has been applied to check the internal consistency between identified criteria and sub-criteria. After finding the evidence of internal consistency, a hierarchical-type model has been developed and analysed using a multi-criteria decision-making as an integrated fuzzy analytical hierarchy process (AHP) and a fuzzy technique for order performance by similarity to the ideal solution (TOPSIS) approach. To make the results more robust and feasible, a sensitivity analysis has also been performed.     

基于加权KL-TOPSIS评价中国大陆食物安全脆弱性的区域差异

[目的]食物安全关系着中国社会经济健康发展与政局稳定。食物安全至今尚未形成统一的评价标准,有必要从脆弱性角度,分层次多角度探讨区域食物安全演变趋势及区域差异,揭示造成脆弱性的主要原因,以便寻找有针对性的应对措施来确保区域食物安全。[方法]通过构建食物安全脆弱性评价框架,建立一个包含多层次及多因素的评价指标体系,再用加权KL-TOPSIS方法计算样本的暴露、敏感、适应及脆弱指数,然后用它们来判别各地区的暴露、敏感、适应及脆弱程度。[结果]1990—2015年,食物主产区、平衡区及主销区资源环境、社会生活、经济发展子系统均为微脆弱,平衡区各子系统最脆弱;暴露、敏感、适应及脆弱水平在区域内与区域间存在差异,各省(市、区)食物安全演变方向也存在差异;大多数地区总体状况是暴露水平低,敏感程度高,尤其是对资源环境高度敏感,且适应能力弱,食物安全处于微脆弱状态。[结论]依原始数据及计算的指数值的变异系数确定权重,不仅客观,还可判断各指标或指数对暴露、敏感、适应及脆弱性的影响程度,从而为降低区域食物安全的脆弱性提供参考;加权KL-TOPSIS方法能够定量评价食物安全各子系统与系统的暴露、敏感、适应及脆弱性;导致暴露、敏感、适应及脆弱水平存在区域差异的原因不同,可为寻找降低食物不安全的对策指明方向,如降低资源环境敏感度与提高经济发展适应度,可显著降低资源环境子系统与经济发展子系统的脆弱性;为降低资源环境暴露度,主产区要合理与节约利用水资源,主销区则须严格保护耕地资源。     

Evaluating museum websites using a combination of decision-making theories

ABSTRACT

The role of museums is very important in cultural and heritage tourism, and a museum website plays an important role in attracting visitors, both physically and online. Therefore, these websites must be evaluated to ensure that their goals are met. However, the evaluation of a website is complex and is often omitted during the website’s life cycle, despite its importance. To simplify this process, this paper presents a framework for evaluating museum websites. The framework, based on an inspection method, is called the inspection evaluation method (IEM). This method uses criteria proposed by several researchers in a review of the different evaluation experiments for museum websites that have previously used an inspection method. IEM, different from all other methods reviewed, uses a combination of an analytic hierarchy process with a technique for the order of preference by similarity to an ideal solution for combining these criteria. The framework was applied to evaluate and rank the websites of five museums known worldwide. This combination uses the advantages of two multi-criteria decision-making theories and reduces their disadvantages.
