A fuzzy multi-criteria decision model for international tourist hotels location selection

The main purpose of this paper is to present a fuzzy multi-criteria decision making (FMCDM) model for international tourist hotel location selection. In this article we created 21 criteria for selecting the international tourist hotel location acquired from literatures review and practical investigations. And the methods of fuzzy set theory, linguistic value, hierarchical structure analysis, and fuzzy analytic hierarchy process are used to consolidate decision-makers’ assessments about criteria weightings. Finally, an empirical study for identifying the international tourist hotel location selection in Taiwan is conducted to demonstrate the computational process and effectiveness of FMCDM proposed by this paper.     

Traditions of sustainability in tourism studies

As sustainability has become an important policy issue in tourism, it is arousing growing discussion and criticism, and an increasing need to understand the nature of the limits of growth. This paper analyzes how these limits are approached and evaluated in discussions on a local scale. The purpose is to recognize that behind the different understandings of them lie distinct traditions that are different in their focuses. These are referred to as resource-, activity-, and community-based traditions of sustainability. Further, the relationship between sustainable tourism and sustainable development is critically discussed.     

China's outbound tourism – Stages,policies and choices

China's outbound tourism has developed rapidly in recent years. This development has been accompanied by a continuous and expanding deficit in the tourism balance of trade, triggering debate among government officials and academia about whether China's outbound tourism development has outgrown general economic development. Understanding China's growth in outbound tourism and its impact has therefore become more than an academic issue; it also affects the future orientation of China's tourism policy. This paper provides a detailed analysis of the tourists, spatial flow, market size, and expenditure. Despite the above concerns, it is suggested that China's outbound tourism is still in a preliminary stage of development and furthermore complies fully with national policies. Therefore, orderly guidance and discretionary market policies are proposed to further facilitate the growth of the outbound tourism market in China.     

Excess capacity,production technology and technical inefficiency in hospitality sector

This article examines the effects of excess capacity on the production cost and technical inefficiency of hotels and restaurants in Norway. The dataset includes a daily unbalanced panel of 94 hotels and restaurants from 2003 to 2014. To accommodate inefficiency, we use an input distance function (IDF). Inefficiency in the IDF means that if inputs are overused by k% then production cost is also increased by k%. We also allow inefficiency to differ across locations and regions by using them as determinants. The results indicate that excess capacity considerably affects the cost and increases inefficiency. The marginal effect on cost increases with excess capacity, but the effect on inefficiency sets in when it exceeds 50 percent. Furthermore, we find less overuse of inputs by firms in small metro towns and the Northern region causing them to be more efficient [except for the Southern and Western regions] than their counterparts.     

会议旅游目的地的选择与评估--以上海市为例

本文首先从理论上研究了会议组织者对会议目的地的选择标准,以及会议结束后怎样对目的地进行满意程度评估。接着通过半开放式的问卷,对2002年在上海召开过国际会议的会议组织者进行了调查,并在调查结果分析的基础上应用“重要性一表现”的研究方法,试图找出上海作为会议旅游目的地的优势和劣势,希望能为整体营销上海作为会议旅游目的地的市场战略提供一些帮助。     

悬臂构件承载力不足的补偿方法

针对有些悬挑构件后来增加立柱支顶的实际工程问题，作者提出了简便合理的承载力补偿方法，并通过进一步的力学分析，证实其可行性和合理性，可供处理类似工程问题参考。     

不同内嵌材料加固钢筋混凝土梁抗弯性能试验研究

分别对内嵌CFRP板、内嵌CFRP筋、内嵌BFRP筋加固钢筋混凝土梁,以及未加固梁进行静力受弯试验,并对试件承载力、荷载-应变曲线以及试件的裂缝形态进行分析。试验结果表明:内嵌CFRP板比内嵌CFRP筋以及内嵌BFRP筋可以更好地提高梁的抗弯承载力;内嵌CFRP板、内嵌CFRP筋以及内嵌BFRP筋都可以较好的约束裂缝的开展。     

Knowledge diversity and coordination: The effect of intrafirm inventor task networks on absorption speed

Research Summary: We combine the absorptive capacity and social network theory approaches to predict how intrafirm “whole” network characteristics affect the firm's speed of absorption of external knowledge to produce inventions. We start from the widely accepted view that distant, externally‐developed knowledge is difficult to absorb into the focal firm's own knowledge production. We suggest that high levels of intrafirm inventor task network diversity and task network density are essential for a diversity of knowledge inputs and coordinated actions regarding knowledge transfer, which in turn, reduces problems related to the absorption of knowledge—especially in the case of knowledge that is distant from the focal firm. The results of an event history study of 113 pharmaceutical firms that engaged in technology in‐licensing from 1986 to 2003 provide general support for our hypotheses. Managerial Summary: Firms keen to keep up with an uncertain and ever‐changing industry environment, can benefit from the speedy introduction of inventions. We examine how firms absorb licensed‐in technologies to nurture the rapid development of own related inventions. We show that a firm's absorption speed depends on the characteristics of the internal collaboration networks among the firm's inventor employees. More specifically, technologically diverse and well‐connected inventor networks improve the firm's ability to absorb external technologies quickly. This applies especially to externally acquired technologies that are unfamiliar to the firm. Depending on the distance of the acquired technology from the focal firm combined with speed‐inducing inventor network characteristics, our estimates suggest that firms can reduce the time needed for absorption by several months.     

分散决策下的双渠道供应链补偿策略——基于消费者渠道选择行为

为了有效解决由于对消费者的争夺从而引发的渠道之间关于定价、服务水平、利润等方面的冲突,基于消费者渠道选择行为,构建了网络直销市场与传统零售市场需求模型和双渠道供应链利润模型,运用Stackelberg模型,在制造商与零售商实施分决策时,通过制造商对零售商实施补偿激励前后的对比,分析了消费者渠道选择行为对网络直销渠道和传统零售渠道定价、制造商与零售商利润以及供应链总利润的影响,并求得最优定价及制造商的最优补偿额度和零售商的最优销售努力水平,进行了不同情况下的双渠道供应链利润的比较分析。结果表明,无论制造商是否实施补偿激励,都应随着网络消费者比例的增加而增加其网络直销价格;零售商的零售渠道价格应根据网络消费者比例的增加先降低到一定水平后再提升。当更多的消费者选择网络直销渠道时,制造商的补偿激励水平和零售商的销售努力程度均会下降。制造商应提高其补偿水平,进而激发零售商提高销售的努力水平,并使双方利润及供应链总利润最大化。研究结果为基于消费者选择行为的供应链补偿研究提供了新方法,对双渠道的供应链补偿研究有借鉴意义。     

下承式钢桁拱桥极限承载力分析

极限承载力分析对于拱桥的设计具有十分重要的意义,理想线弹性结构的理论屈服强度通常采用特征值屈曲分析法得到,但结构材料非线性和几何非线性却使得结构通常无法达到其理论强度极值。利用大型有限元软件ANSYS,同时采用3种分析极限承载力的方法(特征值屈曲法、几何非线性法与同时考虑几何非线性和材料非线性法),对宁波城庄大桥主跨部分进行极限承载力计算分析。分析结果表明,在计算桁式拱桥极限承载力时考虑双重非线性方法求解极限承载力得出的结果比线性方法更符合实际的工程情况。
