Application of Spatial Decision Support System to Blood Bank Information Systems

  • Premasudha B. G


The availability of blood is one of the important requirements in treating medical emergencies; the blood banks do not maintain buffer stocks as required during that time. Thus the buffer stock is obtained from the local donors in the city. In this paper we propose a Geographic Information System (GIS) integrated with blood bank information system to help the blood bank staff to increase or maintain the buffer stock by studying spatial distribution of donors, classification of donors and defining blood bank service areas. Each one of these issues is covered using several GIS functions including buffer analysis, network analysis and overlay analysis. The former is used to produce drive-time to reach blood bank by a required donor and the overlay analysis is applied at the selected blood bank to calculate the size of its donors around the city. The created application is regarded as a spatial decision support system for blood bank information system.
