基于多目标决策模型的区域旅游可持续发展研究——以西藏自治区为例

旅游的可持续发展决定于旅游与人口、社会、资源、环境之间的协调发展,本文建立了西藏地区旅游可持续发展系统的多目标规划模型,针对西藏旅游业发展的三大目标：经济目标、生态目标与群众目标,采用模式搜索算法对多目标规划模型进行求解,获得西藏旅游可持续发展系统不同发展战略下的求解结果。依据求解结果,提出了对西藏旅游可持续发展系统进行过程控制的相关对策建议。     

Hub location problems in transportation networks

In this paper we propose a 4-index formulation for the uncapacitated multiple allocation hub location problem tailored for urban transport and liner shipping network design. This formulation is very tight and most of the tractable instances for MIP solvers are optimally solvable at the root node. While the existing state-of-the-art MIP solvers fail to solve even small size instances of problem, our accelerated and efficient primal (Benders) decomposition solves larger ones. In addition, a very efficient greedy heuristic, proven to be capable of obtaining high quality solutions, is proposed. We also introduce fixed cost values for Australian Post (AP) dataset.

Exploring the use of travel information – identifying contextual market segmentation in Seoul, Korea

As the amount of information is rapidly growing, and ubiquitous urban environments are emerging, the question which kind of information to provide is a major challenge for commercial and public travel-information service providers alike. This paper reports the analyses of recent data, collected in Metropolitan Seoul, about the acquisition of travel information. The study applies CHAID analysis to find homogeneous segments in travel information acquisition. Findings indicate that contextual variables are crucial to explain information acquisition behaviour, depending on decision context. The implication is that both socioeconomic and contextual variables are important to better understand the acquisition (and provision) of travel information. The results have important implications for managers and policy-makers, in particular in the way they respond to dynamic, contextual market segmentation.     

黄浦江两岸地区公共空间可达性研究 ——基于社会网络分析的公共交通评价与 优化策略

黄浦江两岸地区正在打造世界级的滨江公共空间, 如何便捷、多样地抵达滨江公共空间是其规划设计和建设实施 的重要评价指标。将该评价指标定义为滨江公共空间可达性, 指居民利用滨江公共交通系统(常规公交)抵达滨江公共空间的 便捷性和多样性程度。利用社会网络分析方法,以虹口区和徐 汇区的滨江公共空间为例,构建了滨江公共空间可达性模型, 借助地理信息系统(ArcGIS)与计算机编程语言(Python)对现 状可达性进行量化分析评价,并提出优化滨江公共空间可达性 的算法和策略,以期更好地提升滨江公共空间可达性。

Sharing versus collaborative economy: how to align ICT developments and the SDGs in tourism?

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices.     

What determines international tourist arrivals in India?

Using data for 18 major tourist originating countries to India from 2001 to 2015, this study examines the major determinants of international tourist arrivals in India. The results indicate that past experiences of the tourists, per capita income in the tourist originating country, relative costs of living between India and the country of origin, and the level of infrastructure development in India are key determinants of international tourist arrivals in India. Furthermore, both transportation and communication infrastructure are important in attracting tourists to India. In particular, evidence suggests that availability of road and air network and telephone connections has favourable impacts on international tourist arrivals in India. These results are robust to the inclusion of additional variables. These results have important policy implications.
