Optimality and fairness in kidney exchange programmes
Abstract
In this talk we survey some recent developments on the OR aspects of kidney exchange programmes (KEPs). These programmes have been established in most of the Western countries in the last two decades to facilitate the exchange of living kidney donors for those recipients who have willing but immunologically incompatible donors. In the first part, we describe the European practices including the hierarchic optimisation used in the matching runs of the KEPs for computing optimal solutions.
These IP-based methods have been implemented in the simulator software developed in the ENCKEP COST Action (2016-2021) and subsequently incorporated in the KEPSOFT software that provides a common IT-platform for European applications. In the second part, we describe an alternative solution concept based on the individual fairness notion of stability. We explain how this classical cooperative game theoretical concept can incentivise the recipients to register valuable donors or multiple donors in KEPs. Finally, in the third part, we present new results on international KEPs, where credit-based compensation schemes have been proposed to balance out the benefits of the countries when merging their national pools.
