Parameters of discrete event simulation models.
| Name | Personnel | Capacity | Condition | Distribution of length of stay (hour) |
| Operating hours | NA | NA | Stops patient check-in at 8.5 hours and closes at 9 hours | NA |
| Patient arrival | NA | NA | Arrival rate: 6 per hour Mean interarrival time: 1/arrival rate | Poisson process |
| Patient check-in | Staff | 3 | NA | Normal (0.05, 0.01) |
| Public waiting room | NA | 20 | Normal (0.17, 0.034) | |
| Consent room | LVN/trainee | 1 | NA | Normal (0.17, 0.034) |
| Dressing room | NA | 3 | NA | Normal (0.03, 0.006) |
| Gowned waiting room | NA | 5 | NA | Normal (0.017, 0.0034) |
| AI assessment (revised workflow only) | Radiologist | NA | The percentage of the screener needs a diagnostic imaging examination Normal (12%, 5%) | Normal (0.25, 0.05) |
| Sensitivity analysis: AI recall rate: uniform (0.1, 0.2, 0.3) Radiologists agree with the AI rate: uniform (0.7, 0.8, 0.9) |
Sensitivity analysis: AI: normal (0.05, 0.01) Radiologist: normal (0.20, 0.04) |

| 2D/3D Screening mammography | Mammo technologist | 3 (mammo); | 50.3% screeners/day | Normal (0.17, 0.034) |
| Diagnostic imaging | Mammo/US technologist | 2 (US) | 45.0% diagnostic imaging patients/day (Diagnostic mammo + diagnostic US: 80%; Diagnostic US: 10%; Diagnostic mammo: 10%) |
Diagnostic mammo: normal (0.5, 0.1); Diagnostic US: normal (0.5, 0.1) |
| Core needle biopsy | Mammo/US technologist, radiologist, LVN/trainee | 4.0% US-guided biopsy/day 0.7% stereotactic-guided biopsy/day |
US-guided biopsy: normal (0.75, 0.15); Stereotactic-guided biopsy: normal (1.25, 0.25) |
Notes: Imaging equipment is shared resources across all imaging examinations and procedures (e.g., mammography equipment can be used for screening mammography, diagnostic mammography, or stereotactic-guided biopsy). Abbreviations: LVN: licensed vocational nurse; AI: artificial intelligence; 2D: two-dimensional; 3D: three-dimensional; mammo: mammography; US: ultrasound; NA: not applicable.
