Database model for kidney exchange programmes simulation tool

Kidney exchange programmes (KEPs) have been organized for patients to exchange their willing, but incompatible donors among each other in a framework controlled by experts. Thousands of patients have already been matched and received kidneys from compatible donors in national and international KEPs in Europe, and elsewhere. To evaluate the performance of KEPs various simulator tools have been developed and tested on real historical and generated data for difference settings and optimization polices. In this paper, we propose a database model that can be used in such KEP simulator tools, and can serve as an example for databases in information systems of real applications.
