As a consequence, conventional line assemblies reach the limits of their economic viability. Dissolving the coupling and cycle dependency of stations in matrix assemblies offers the potential to simultaneously improve flexibility and efficiency while maintaining the flow principle. Matrix and line assemblies form the flow-oriented assembly structures in which assembly objects move according to the flow principle. During structure planning, assembly planners are increasingly faced with the question of which configuration of flow-oriented assembly structures meets the requirements of their use case and how flexibility can be objectively incorporated as a decision criterion. Classifications for assembly structures help to create transparency about configurations in the solution space of structural planning by differentiating central dimensions. Due to the high complexity of matrix assemblies, existing classification approaches cannot be used, as the dimensions and characteristics used do not differentiate configurations clearly. Furthermore, existing evaluation approaches are not suitable for the data-based quantification of flexibility as decision support in the early phase of structural planning. As a result, the efficiency and effectiveness of planning flexible, flow-oriented assembly structures are not ensured. To address these challenges, this thesis develops a structural planning methodology for the efficient and data-based determination of flexible, flow-oriented assembly structures by means of a classification. A defined, redundance-free set of flexibility criteria allows to quantitatively specify the flexibility requirements of a use case through the targeted assessment of production program and process time data. A level-based classification organizes the configurations of flow-oriented assembly structures and breaks down the interdependencies of the combined structure elements. This eliminates the effort involved in structuring the solution space of structural planning and makes planning complexity efficiently manageable. Furthermore, the structure configurations are prioritized on the basis of a systematic comparison of the required and provided flexibility of configurations for decision support. This ensures that the structure configurations offer sufficient flexibility and structural planning delivers high-quality results. The operationalization in a methodology and its integration into a holistic assembly planning procedure makes the collected insights accessible to assembly planners in a compact form. Overall, the methodology enables the efficient and transparent determination of assembly structures according to the specific flexibility requirements of an use case.
