On guiding simulation model reuse from the conceptual modeling stage

This study proposes a five-stage decision-making process to streamline the reuse of simulation models from as early as the conceptual modeling stage of a new study. The stages assist modelers in selecting pre-existing conceptual and/or formal models, testing their suitability for reuse, selecting model components deemed reusable, adapting them to the new modeling requirements, integrating them into a ‘final’ conceptual model and, prior to its computer coding, carrying out various steps of conceptual model validation along the way. Key novelties are: a structured approach to model reuse, an emphasis on validation steps, and the integration of practical tools. We discuss the advantages from following such a process based on evidence from a recent project that looked at enhancing aircraft turnaround processes.
