Missions involving multiple spacecraft can offer a number of benefits over single platforms. Earth Observation (EO) constellations have the potential to offer critical services for the society such as global monitoring and disaster management. This trend is opening new challenges to the automated Mission Planning & Scheduling (MPS) systems aiming at gaining maximum value from the constellations,...
In the last decade, Dynamic Optimization Problems (DOP) have received increasing attention. Changes in the problem structure pose a great challenge for the optimization techniques. The Ant Colony Optimization (ACO) metaheuristic has a number of potentials in this field due to its adaptability and flexibility. However their design and analysis are still critical issues. This is where research on formal...
GEEWHEZ is a new multipurpose platform specifically designed for SMEs that have visitors and the exhibition of animals as main business. The GEEWHEZ platform aims to deal with basic aspects of resource management tools (e.g. global finances) and a number of new applications of interest for the management of theme and animal (zoos and aquaria) parks. Among other applications, GEEWHEZ is designed to...
This paper describes the algorithms used in a planning and scheduling software tool developed for the European Space Agency in the framework of the Mars Express mission. The planning and scheduling algorithm computes a feasible schedule for the transmission of telecommands (TCs) from the ground segment to the space segment, complying with a number of technical constraints. Owing to the distance between...
