Ontology-based production planning under the consideration of system robustness

Volatile markets and high customer requirements regarding schedule reliability increase the relevance of robust prodution planning. To achieve robustness in planning, system-inherent buffers are used. Buffers include resource capacities that are kept free to respond to changes. Targets other than achieving the production plan are not considered, so a trade-off between reliability and the further development of the manufacturing process is not possible. This paper presents a new approach for production planning based on robustness analysis that enables a multi-criteria optimization. An information system enables the companyspecific design of the robustness analysis.
