The Development of an Online Blood Donation Queue Management System with Advance Notifications to Enhance Operational Efficiency

Abstract

This study aims to develop and evaluate the performance of online blood-donation queue reservation system equipped with advance appointment notifications, designed to address difficulties in booking, communication constraints, and inadequate donor preparedness factors that critically affect donation regularity and the adequacy of blood reserves in healthcare facilities. The proposed system was designed through a systematic user requirements analysis combined with structural design techniques, including the Context Diagram, Data Flow Diagram, Data Dictionary, and Entity Relationship Diagram, to ensure architectural and functional coherence. The system evaluation indicates that all modules operate correctly according to the specified requirements, with data management conforming to relational database constraints. The booking, notification, user-management, and information presentation functions demonstrate stability and effective responsiveness for both administrators and general users. The developed system therefore exhibits strong potential for real-world implementation to support blood supply management, reduce operational errors, and enhance donor readiness at the operational level.
