TBO运行是未来民航管制运行的主流方向,为缓解当前航路交叉点流量,减少拥堵的情况下,结合TBO运行背景,利用降维法搭建井字型构型,建立了航路交叉点模型,对单个航路交叉点和井字型构型交叉点的容量公式进行研究。结合民航某航路交叉点在高峰时间段进行仿真,结果表明井字型构型容量相较于单航路交叉点容量提高了35.4%。进而设置模型的目标函数,运用遗传算法对模型进行求解,得出井字型构型交叉点相比单个航路交叉点在航班延误成本方面降低了49%,在旅客平均延误时间上减少了52.7%。结果表明,对于大流量航路交叉点,通过变换井字型构型可以有效地疏导拥堵,对航路资源进行协同分配。  相似文献

This paper examines the diffusion of information around the initial public offering (IPO) process and identifies transaction partners on which IPO firms are dependent. Using a resource payments perspective, we argue that this dependence will lead to greater cumulative abnormal stock returns for transaction partners when this information is revealed in the market (when the initial form S‐1 is filed with the SEC). Moreover, we examine the uniqueness of the resource configuration between the IPO firm and transaction partners and find that greater uniqueness is associated with higher valuation for these transaction partners. We also find that multiple dependencies (by the IPO firm) reduce the valuation effect for transaction partners, indicating that a bargaining effect reduces the potential value that any transaction partner can appropriate.

The leadership assessment questionnaire (LAQ) is a 360 degree survey instrument designed to help organizational leaders identify their own style of leadership and formulate appropriate development objectives. It is designed to provide avenues for development of an executive team in which multiple leadership archetypes are represented. The LAQ is based on eight leadership archetypes – strategist, change-catalyst, transactor, builder, innovator, processor, coach, and communicator. These archetypes are representations of ways of leading in a complex organizational environment. In this article, we discuss the development, design, and psychometric analysis of the LAQ. We detail the conceptual foundations of the questionnaire and the psychometric methods used to confirm the validity and reliability of the instrument. We conclude with avenues for future research.  相似文献

We propose a set of organizational efforts that can help companies accumulate and learn knowledge related to new product development (NPD) activities. We call it the NPD learning process and argue that a set of coherent human resource management (HRM) practices, termed knowledge-oriented human resource (HR) configuration, can facilitate the NPD learning process. Collecting survey data from Taiwan, we find that the knowledge-oriented HR configuration is positively related to the NPD learning process and that the NPD learning process is positively related to managers' perceived new product performance. This study contributes to the literature of strategic HRM and innovation management.  相似文献

Human resource (HR) practice transfer is an important topic in the domain of strategic international human resource management (SIHRM). Previous research in practice transfer has emphasized the challenges arising from the institutional distance between the home and host countries. However, potential opportunities due to this distance have been largely overlooked. Shifting the focus away from looking at institutional distance as a constraint, we examine the possibilities of strategic opportunities that exist because of institutional distance. We argue multinational corporation (MNC) subsidiaries can exploit these opportunities to gain competitive advantage. Building upon SIHRM literature, institutional theory and the resource-based views, we propose a conceptual framework explaining how institutional environments present strategic opportunities. We argue that these strategic opportunities are most abundant in the case of moderate institutional distance between the two countries. Building upon the conceptualization of strategic opportunities, we propose a model of subsidiary HR configuration, and then we explain how an HR configuration could be a source of competitive advantage. Further, we examine the role of MNCs' overall SIHRM orientation in relation to the identification and exploitation of strategic opportunities.  相似文献

兰州属于严重缺水的西北城市,年均降雨量偏少,地表水资源贫乏,水资源供需矛盾不断加剧。文章采用线性和非线性方程形式对兰州市农业、工业、生态和城乡生活用水需求进行模拟和预测,并在不同的水资源供给方案下得到未来时期内兰州市及各区县的时空匹配缺水量。结果显示:未来兰州市水资源短缺问题较为严重,可预测的缺水量最小值为4.605亿m3/a,缺水量最大值为15.448亿m3/a。在未来需水量预测中,农业和生态用水需求呈现为不断上升趋势,工业用水需求呈现为"U"型趋势,城乡生活用水需求呈现为倒"U"型趋势。并且,各区县的水资源空间匹配失衡状况较为严重。  相似文献
