This thesis focuses on single- and multi-objective optimization approaches applied to TSPTW and coupled with an in-depth study of the associated research landscapes.
Webthe cities by customers. Introducing travel time between customer location pairs and a time window for each customer, which requires the vehicle to visit the customer during a pre-speci ed period of time, gives the Traveling Salesman Problem with Time Windows (TSPTW). The TSPTW is even more relevant to logistics, as customers often request, or WebJul 21, 2016 · The scheduling problem of an Agile Earth Observation Satellite is to schedule a subset of weighted observation tasks with each a specific “profit” in order to maximize the total collected profit, under its operational constraints. The “time-dependent transition time” and the “time-dependent profit” are two crucial features of this ...
