Researchers have emphasized that different factors have to be considered when discussing the flexibility of a single machine and that of a group of machines. The present research focuses on proposing methods for measuring machine-group flexibility, which is an extension of the model for...

This paper presents a simulated annealing based heuristic approach for the team orienteering problem with time windows (TOPTW). Given a set of known locations, each with a score, a service time, and a time window, the TOPTW finds a set of vehicle tours that maximizes the total collected scores....

Typically international airports have features quite distinct from those of regional airports. We discuss the process of developing a Decision Support System, and appropriate mathematical models and algorithms to use for making gate allocation decisions at an international airport. As an...
