Purpose This paper aims to build a scientific evaluation index system for regional low-carbon circular economic development. Taking Sichuan Province as the empirical research object, the paper evaluates its low-carbon circular economy (LCCE) development level and proposes policy recommendations for climate change improvement based on the evaluation results. Design/methodology/approach This paper, first, built an evaluation index system with 30 indicators within six subsystems, namely, economic development, social progress, energy consumption, low-carbon emissions, carbon sink capacity and environmental carrying capacity. Second, develop an “entropy weight-grey correlation” evaluation method. Finally, from a practical point of view, measure the development level of LCCE in Sichuan Province, China, from 2008 to 2018. Findings It was found that Sichuan LCCE development had a general downward trend from 2008 to 2012 and a steady upward trend from 2012 to 2018; however, the overall level was low. The main factors affecting the LCCE development are lagging energy consumption and environmental carrying capacity subsystem developments. Research limitations/implications This paper puts forward relevant suggestions for improving the development of a low-carbon economy and climate change for the reference of policymakers. Originality/value This paper built an evaluation index system with 30 indicators for regional low carbon circular economic development. The evaluation method of “entropy weight-grey correlation” is used to measure the development level of regional LCCE in Sichuan Province, China.

A low-carbon evaluation index system for container terminals is proposed on the basis of their characteristics and the concept of low-carbon port. This system takes quantitative indexes as the core, supplemented by qualitative ones. The weight of each index is determined by AHP, and then a fuzzy comprehensive evaluation model is established according to the AHP-fuzzy comprehensive evaluation method. Finally, the proposed model is applied to a certain region of a container terminal, and the result indicates that the proposed evaluation index system and evaluation model can provide a reference for the low-carbon level evaluation of container terminals.

The aim of this study is to investigate and discuss the potential security issues arising from the deployment of the Cloud Enterprise Resource Planning system, and to propose a perfect and standard set of security evaluation index system for Cloud ERP security issues. Considering the issues which may be inherent in the conventional Enterprise Resource Planning systems and new ones brought by Cloud Computing, Cloud Platform, Cloud ERP, we use text mining technology to mine the related standard files in this paper. Since the standard literature is based on the comprehensive results of technology, science and practice, its characteristics of standardization, objectivity and validity also ensure the effectiveness and applicability of indicators. By using NLP methods, we construct a Cloud ERP security evaluation index system consisting of five parts: evaluation method security, information access security, data security, management security and others. The entropy method is used to assign weights for the Cloud ERP security evaluation index system, which is more scientific and rational and the method moderates the lack of objectivity caused by traditional evaluation methods which over-relies on evaluators. By analyzing cases of Cloud ERP collected in various application reports and research papers, we improve our system and find that compared to other evaluation systems, our system can evaluate the security of Cloud ERP more comprehensively.

Abstract In order to improve the evaluation system for the water conservancy photography creation base, evaluation indicators regarding the aspects of photographic resources, photographic elements, and water resources were selected to construct an evaluation index system, and the evaluation criteria for each index were provided. The optimal comprehensive weight for each evaluation index was determined following the moment estimation theory. The quantitative evaluation of the water conservancy photography creation base was carried out combined with the scoring standards for each index. The evaluation index system constructed here was then discussed in the application. This indicated that the evaluation index system is suitable in determining the construction status of the evaluated cases, thus, verifying its rationality. The comprehensive weighting of the indicators based on the moment estimation theory made the evaluation method more scientific and the corresponding results more reliable. This enabled the entire evaluation system and method to provide the theoretical support for the scientific evaluation of the water conservancy photography creation base.
