Abstract

The Time Dependent Orienteering Problem with Time Windows (TDOPTW) consists of a set of locations with associated time windows and scores Visiting a location allows to collect its score as a reward Traveling time between locations varies depending on the leave time The objective is to obtain a route that maximizes the obtained score within a limited amount of time In this paper we target the use of public transportation in a city, where users may move on foot or by public transportation The approach can also be applied to the logistic sector, for example to the multimodal freight transportation We apply an hybrid approach to tackle the problem Experimental results for the city of San Sebastian show we are able to obtain valid routes in real-time.
