Description of the research topic:

Taking into account the effects of possible faults of executing solutions of operations research problems even in the planning phase has huge importance in several application areas, like in case of logistical, industrial and testing processes, for example. The research has dual purposes: on one hand, we intend to develop fault-tolerant system design methods which are able to compensate efficiently the immediate breakdown of some operation units. On the other hand, we want to design and implement algorithms for optimal (re-)scheduling of already planned systems.
As methodology, we reflect to the dynamic versions of Vehicle Routing Problem, and heuristic algorithms for scheduling workflows. We intend to develop and analyze special methods for the specialities of the application area.
We analyze the possibilities of applications of metaheuristic algorithms, which algorithms are able to handle efficiently the lack of broken down resources.
