Planning of Internal Production Networks

Planning of Internal Production Networks - Knorr-Bremse

The development of the railway vehicle industry is characterized by the continuing trend of globalization and consolidation of subsystem suppliers. In this context tapping new markets with high market growth plays a prominent role leading to an increase in the variety of products (e. g. local variants) and an increasing complexity of logistic dependencies of globally distributed production sites. This development leads to an increased need of planning and coordination of production sites and therefore planning processes of subsystem suppliers gain in importance. At the same time existing planning processes are challenged by an increase in complexity which is to be coped with to assure future competitiveness.

A hierarchical planning method that meets the requirements of a globally distributed production is developed in cooperation with Knorr-Bremse Systems for Rail Vehicles in Munich. The overall planning task is divided into four subtasks based on the time frame, scope of consideration and the decision hierarchy of the company. Coordination processes are defined to combine these subtasks to an overall planning process while mathematical optimization models are used for representing and solving the subtasks.
