1、云龙湖自助旅游系统的设计和开发,硕士论文近年来,随着旅游消费观念的转变,越来越多游客选择自助旅行,但是面对陌生的景区,复杂的旅游环境,游客很难在没有向导引领的情况下完美的到达旅行目的.本文针对游客外出旅行中面临的旅游道路规划问题,利用图论和运筹学的思想,建立旅游道路规划的数学模型,综合考虑用户出行中的时间、空间等多种需求,实现旅游道路的规划,为用户推荐知足其个人需求的旅游线路.结合上述研究工作,基于 Android 平台完成了云龙湖自助旅游系统的设计和开发.本文主要研究内容如下: (1)建立基于定向问题的旅游道路规划问题模型.通过对旅游道路规划问题进行系统分析,比照经典道路规划问题模型的优势和
2、缺乏,选择定向问题作为基础模型.综合考虑景区旅游环境,作出合理假设,确定约束条件,对基础模型进行扩展,建立旅游道路规划问题数学模型.保证在知足总时间约束的条件下以最大化道路收益值为目的选择景点,这些景点构成最终的旅游道路. (2)提出适用于旅游道路规划问题的改良 A*算法.根据问题需求和算法存在的缺乏,改良 A*算法的启发规则,算法规则中考虑景点得分以及总时间约束,并结合问题实际,以图最短时间作为算法需要的估计时间.通过实验表示清楚,改良后的 A*算法与传统算法相比,得到的结果道路收益值更大且时间利用率更高层次,更合适于求解旅游道路规划问题.最后以云龙湖景区为例,使用爬虫技术收集景区数据,完成
3、了景区内景点得分、景点游览时间、交通时间以及停车时间等条件参数的合理量化,实现了景区内的旅游道路规划. (3)设计并实现云龙湖景区的自助旅行系统.本文以云龙湖景区为应用实例,根据需求分析,设计自助旅行系统架构和功能模块,系统设计包含景点服务、旅行安全以及道路规划三大模块.以旅游道路规划问题的理论研究成果为基础,利用 Android 编程技术、百度地图 API 以及 GPS 定位技术,开发实现了基于Android 平台的云龙湖自助旅行系统,能够为游客提供景点介绍、道路推荐、电子地图等多种服务. 本文关键词语:定向问题,A*算法,旅游道路规划,自助旅行系统 Abstract In recent y
