基于禁忌搜索算法的机场外航服务人员班型生成研究

针对机场外航服务人员班型生成面临的任务量大,约束条件复杂,人工生成班型方案困难等问题背景,考虑员工对任务具有层次资质,班型的各类劳动法规等约束条件,以最小化班型方案总工作时间为优化目标,研究构建了面向多任务层次资质场景下的班型生成优化模型,并设计禁忌搜索算法进行求解。在首都机场外航服务部实际排班数据集上进行实验,验证了模型和算法的实用性和有效性,实验结果表明,求得的班型方案相比较现有人工生成的班型方案,能满足所有约束条件且总工作时间更短,总服务人数更少,提高了机场资源利用率。

面向班型动态生成的地服人员排班算法

面向班型动态生成的地服人员排班旨在动态生成班型,并将员工分配到班型中,以班型为航班地面保障单元.现有面向班型的人员排班算法是建立在固定班型数和班型内的员工资质数,未考虑班型数未知的重要前提.为此,提出面向班型动态生成的地服人员排班算法,其核心思想是通过block Gibbs抽样迭代优化班型内人员构成、班型内航班集和班型生成.在某机场值机人员的数据集中验证此算法,实验结果表明,在满足员工层次资质、员工白夜班和班型动态生成的约束下,算法能够生成合理的班型.

Innovation, Competitiveness and Prosperity： A Factor Analysis of Innovation Indicators in Spain

Competitiveness is a wide concept applied to many fields, especially in economics. The study of tourism competitiveness has been focused on different factors that can enhance the prosperity of a destination. One of these factors is innovation. Innovation makes destination＇s enterprises more advanced and efficient, therefore more productive. Innovation is an enhancer of competitiveness and a generator of prosperity because innovation in every aspect （technology, knowledge, organization, and processes） will provide a better quality of life for the inhabitants of the destination. The incidence of innovation on these concepts is validated by a structural equation model. We measure innovation by a range of indicators and through a factor analysis; we get the most relevant indicators of innovation for the model developed in Spain.
