Today continuous planning is a prerequisite for competitiveness. Methods are required, that allow the handling of complexity in rapidly changing and complex networks. Model based methods provide insight in these networks and therefore help realizing advantages in competition. The vision of a modeling plant for building the required models effectively and in an industrial scale and concepts for long term usage of models will make model-based methods attractive for the industry. The validation of planning results using a model will advance the quality of planning and thereby create advantages in competition.
