An actual study about potentials and needs of action in the range of factory planning projects shows clearly that the used process models can’t handle the dynamic and the complexity in these projects. For this reason, the University of Applied Science Landshut has been developing within the Landshuter Produktionssystem (LPS): CLean Production - Lean & Clean a new factory planning methodology. This allows for the first time to design the factory structures from beginning based on lean criteria in connection with the planning and control. The method will also satisfy the requirements referred because of an agile process model.
