Energy policy, environmental planning and economic development play a key role in sustainable development. Sustainable development requires suitable and strategic policies satisfying multiple and conflicting objectives. Fuzzy goal programming (FGP) is a well-known approach in multi-criteria decision-making for its practical application. In this article, a FGP approach is proposed to analyse environmental, energy and sustainability goals of India by the year 2030 with reference to the key economic sectors of India. The presented model analyses the improvement opportunities, requirement of efforts and implementation of the sustainable development plans. Numerical illustration is also provided for validation and application of the proposed model. 相似文献

In this paper we examine the question of whether and how municipal landscape plans exert a positive influence on and/or correlate with selected aspects of the landscape. To this end, a representative sample of municipal landscape plans in Germany and a statistical-quantitative evaluation approach are used to uncover correlations between planning and landscape development. As a result, we can show that municipalities which draw up a landscape plan have a higher proportion of natural areas and a lower hemeroby index, i.e. a lower level of human influence. The model also reveals a significant relationship between the quality of the landscape plan as well as its duration of impact and the density of landscape structural elements. It is also determined that municipal landscape plans help protect grassland areas. The indicator-based method provides impulses for the international discussion on the evaluation of plans. 相似文献

The traditional mean–variance approach has been complemented by alternative theories that use risk measures different from standard deviation of returns or involve additional distributional features of returns like skewness and kurtosis. We propose a portfolio choice model that combines different distributional characteristics of the returns in the decision-making making process, considering preferences of investors which are modeled as non-statistical uncertainties of investors using fuzzy theory. We use 20 stocks of the S&P500 from January 2013 to December 2017. We assess the obtained portfolios’ performance, and the diversified behavioral portfolios outperform than the mean–variance portfolio. This methodological proposal can be seen as a strong managerial tool to make investment portfolio decisions. 相似文献

2016年5月《国务院办公厅关于深入推行科技特派员制度的若干意见》发布实施,但其实施效果如何有待验证。构建科技特派员制度实施绩效评估指标体系,利用改进熵值法和官方统计数据,对中国省域科技特派员制度实施绩效进行实证评估,并对评估结果进行聚类分析。结果表明,中国大多数省份科技特派员制度实施绩效水平较低;根据实施科技开发项目、形成利益共同体、服务农民情况、推广服务和扶贫成效5个绩效评估维度,可以将中国内地31个省份划分为5种类型;即使是总绩效水平较高的地区,在科技特派员制度实施绩效方面也存在一些短板。 相似文献

The early stages of innovation involve high levels of uncertainty, leading to it being labelled as the “fuzzy-front end” (FFE). Although openness has been identified as pivotal to innovation performance in the open innovation literature, little effort has been put into exploring its role in the FFE. Specifically, this study examines ‘openness competence’ within the FFE–i.e., the ability of a FFE team to explore, gather and assimilate operant resources from external sources by means of external searches and inter-organisational partnerships. The aim is to investigate the impact of openness competence on front-end uncertainty reduction and service innovation success. Data were obtained from a survey of 122 IT-based service innovation projects implemented by IT service provider firms in Thailand. The results suggest that openness competence positively influences both the degree of uncertainty being reduced during the FFE and the overall success of service innovations. These findings offer several implications for research on open innovation and the FFE as well as encouragement to managers to apply a more open approach to the FFE of their service innovation projects. 相似文献

In the Comprehensive Spending Review and in the Budget 2010, the Liberal–Conservative coalition has announced cost‐cutting measures in the benefit system. Some of these measures can be interpreted as ‘random cuts’, where the given scope and structure of a spending programme is retained, while bits and pieces are chopped off here and there. Others can be interpreted as more strategic measures, or reconsiderations of the proper role of government in the respective area. However, where the coalition has pursued a more strategic approach, it has not followed it through consistently. The coalition's consolidation strategy relies too much on temporary caps and freezes, which will eventually expire and give way to renewed spending pressures. 相似文献

Nowadays the profitability of airports is largely based on non-aeronautical or commercial activities, and particularly on retail and food and beverage services. Further, researchers concur that shopping, eating and drinking in airports have to be considered an important part of tourists' experience and activities that can significantly enhance or damage the tourist destination image. Despite this, there is still little research that analyses how service quality (SQ) is perceived by passengers consuming food and beverages (F&B) in airport areas. This study aims to deepen the scientific debate on this topic. Specifically, this study applies fuzzy numbers with a sample of 551 passengers flying from Olbia-Costa Smeralda Airport (Sardinia Region, Italy) with the aim of determining how they perceive the SQ delivered by F&B retailers and whether age plays a determinant role in segmentation. Findings reveal which F&B features outperform others; furthermore, they show that age is a moderating factor in consumer satisfaction, with older passengers being less satisfied than their counterparts. This study adds knowledge to the literature devoted to SQ, applying a fuzzy number approach to the under-investigated research area related to F&B consumption in airport areas. Further, it provides information useful to airport managers on the features of F&B services that are most important in shaping consumer satisfaction, based also on their age. Limitations of the study are also discussed and suggestions for future research are given. 相似文献

Cruise tourism is a significant growth trend in Europe and America. However, in recent years, it has gradually gained popularity among tourists in Asia, showing great potential. Strategically located in Asia, Taiwan is an ideal place to develop cruise tourism. This study explores how Taiwan could build a niche in Asia's cruise tourism industry. It applies the Fuzzy Delphi and Fuzzy IPA methods. According to study results, Taiwan should prioritize on the following aspects: establishing a 24-h tourist service center, providing a complete cruise logistics service, inviting foreign cruise operators to inspect special resources in Taiwan, cooperating with other Asian countries, setting up a special government unit, as well as planning and developing unique tourism resources. 相似文献
