基于游客满意度的县域旅游公交网络优化设计

Optimization Design of County Tourism Bus Network Based on Tourist Satisfaction

摘要: 近年来，旅游业发展迅速。县域常因为其具有优美的自然风景成为旅游的目的地，旅游公交作为服务县域旅游的重要组成，本文从游客旅游体验出发，提出了一种多目标优化的旅游公交网络设计模型。模型综合考虑游客平均时间成本和旅游体验指数，以游客满意度最大化为优化目标，利用贪婪算法生成初始解，并通过遗传算法对初始解迭代改进计算最大游客满意度的公交线路方案。通过数值案例验证模型在旅游公交的设计中的合理性。结果表明，算法可以有效的求解县域旅游公交网络设计模型；游客平均时间成本对游客满意度的影响度会导致旅游公交线路设计要素产生变化。

Abstract: In recent years, tourism is developing rapidly. The county often becomes a tourist destination because of its beautiful natural scenery, and for tourist buses as an important component of the service county tourism, this paper proposes a multi-objective optimization tourist bus network design model from the tourists’ travel experience. The model comprehensively considers the average time cost of tourists and the tourism experience index, takes the maximization of tourist satisfaction as the optimization objective, generates the initial solution by using the greedy algorithm, and iteratively improves the initial solution by genetic algorithm to calculate the bus route scheme with the maximum tourist satisfaction. The rationality of the model in the design of tourist buses is verified through numerical cases. The results show that the algorithm can effectively solve the county tourism bus network design model; the degree of influence of the average time cost of tourists on tourists’ satisfaction will lead to changes in the design elements of tourism bus routes.
