Number of patients waiting to various steps of the RT process by week as given by the output of the proposed simulation model over RT preparatory steps. RT tasks from left to right: 1. Mould, 2.PET, 3. CT, 4. MRI, 5. Target definition (TD), 6. Treatment planning (TP), and 7. QA. Top row corresponding to results for curative treatment intent (a), middle row for palliative treatment intent (b) and bottom row when disregarding treatment intent (c). The experiment includes nine different group scenarios: reference=each RT workflow handled separately, Pareto_80/20=80% of workflows handled separately and remaining 20% merged into one additional group, A1/2_75/80/85=proposed grouping strategies where all elements correlated with one main element [1]/correlated with each other [2] for utilization rate correlation coefficient cutoffs up to r=0.75/0.80/0.85, and all-in-one=all RT workflows merged into one group. Abbreviations: CT= Computed Tomography, MRI= Magnetic Resonance Imaging, PET= Positron Emission Tomography, QA=Quality Assurance, RT= Radiotherapy, TD=Target definition and TP=Treatment planning
