AI technologies for time/resources planning and scheduling

Automated planning and scheduling based on Artificial Intelligence technologies for the optimization of action sequences to be executed by space missions, ground-based observatories or astronomical instruments. Planning solutions are complex and have to be discovered and optimized in a multidimensional space. A combination of Metaheuristic Optimization (e.g., genetic algorithms, multiobjective evolutionary algorithms) and ad-hoc heuristics is applied to obtain a flexible, robust and optimal schedule of operations to be performed in a specific observatory for a period of time that can range from minutes (short-term schedule) to several months or years (long-term schedule). Action sequences are derived for unknown, dynamic and nondeterministic environments -such as astronomical observatories-, and are reviewed and adapted during their execution, which adds significant complexity to the solution of the problem.
