In order to improve the robustness of a railway system in station areas, this paper introduces an iterative approach to successively optimize the train routing through station areas and to enhance this solution by applying some changes to the timetable in a tabu search environment. We present...

During the past decades, several joint maintenance and inventory optimization systems have been studied in literature. Compared to the sequential optimization of both models, Kabir and Al-Olayan (1996) reported a remarkable influence on total cost due to their joint optimization method. This...

High logistics and handling costs prevent the bioenergy industry from making a greater contribution to the present energy market. Therefore, a mathematical model, OPTIMASS, is presented to optimise strategic (e.g. facility location and type) and tactical (e.g. allocation) decisions in all kinds...
