Designing a Digital Twin for Equitable Blood Donation Logistics in Geneva

Year: 2026

Type: book-chapter

Abstract: INTRODUCTION: Mobile blood drives can reach underrepresented donors, yet their planning rarely uses data-driven optimization. METHODS: We designed a digital twin with a four-layer architecture integrating GIS analysis and MILP optimization. Six accessibility indicators feed an objective function maximizing expected donations under operational constraints. RESULTS: An illustrative scenario shows evening slots yielding ∼25% more donations than midday, with Thursday evening peaking at 33-34 expected donations. CONCLUSION: This proof-of-concept demonstrates the feasibility of combining spatial analysis and mathematical optimization for equitable blood collection planning in Geneva.
