"Combination of planning methods in a comprehensive production planning approach for sequenced production lines";
Talk: 62nd General Assembly of CIRP, Hong Kong; 2012-08-19 - 2012-08-25.

Medium-term sales and operations as well as medium to short-term production planning in customer order driven production processes are performed using a cascading planning process. A lack of
coordination and feed back between different planning phases causes problems with a negative effect on costs in production that originate from unfeasible production programs. Based on a system for the
classification of planning restrictions the planning process will be controlled utilizing a newly developed
combination of the methods of Linear Programming and Constraint Programming. The result is a formal logic to combine the different planning horizons and the two sets of planning methods.
