CAD-based Assembly Sequence Planning for Increased Operational Flexibility Dataset

<p>Operational flexibility represents the ability to adapt to changes in production or assembly<br> processes. It is a crucial aspect of assembly sequence planning for a dynamic environment (such as<br> large-scale assembly systems). The choice of graph model, such as precedence graph or AND/OR<br> graph, can significantly impact operational flexibility. The state-of-the-art research has demonstrated<br> the utility of precedence graphs and AND/OR graphs for flexible assembly lines.<br> However, AND/OR graphs offer the potential for even greater operational flexibility but with a higher<br> computational cost. Further research is still needed on the detailed effects of precedence graphs and<br> AND/OR graphs on operational flexibility and the limits for their application to large-scale assemblies.<br> The trade-offs between different models and their impact on operational flexibility and computational<br> costs is observed.</p> <p><br> <strong>1st underlying research question: </strong>Which graph model, derived from CAD-based assembly-by-<br> disassembly, can increase the operational flexibility in integrated assembly sequence planning and job<br> scheduling problems?</p> <p><br> A hypothesis is formulated to answer this research question, which will be used to design an experiment<br> and be tested.</p> <p><br> <strong>Hypothesis 1: </strong>The AND/OR graph can be utilized to improve the operational flexibility in comparison<br> to the precedence graph.</p>
