Decision support system for multiproject scheduling of resources in blood collection programmes

A model of a repetitive multiproject management is introduced that includes uncertainties in activity durations, and the corresponding quantities of resources needed. Following the convention, a project is viewed here as a network of related activities aimed at the accomplishment of a predetermined objective at a given deadline. A project has a starting point in time and a preplanned completion point and so does each activity within it. The structural and operational characteristics described here are drawn from organization and management theories and used to describe project organization. This is demonstrated by means of field data gathered from a sample of ‘bloodmobile projects’ - an organized effort for the collection of blood donations in support of medical needs.
