Kidney exchange is an increasing modality for transplanting end stage renal disease patients with an incompatible living donor. Typically, the aim is to find an allocation of donors to patients that is optimal with respect to multiple hierarchical criteria. This paper presents an iterative...

This paper studies participation of unspecified donors in kidney exchange through simultaneous domino paired donation (DPD) and non-simultaneous extended altruistic donor (NEAD) chains. It extends existing research by investigating the termination of chains, the possibility of transplantation...

In this paper, we present a branch-and-price method to solve special structured multistage stochastic integer programming problems. We validate our method on two different versions of a multistage stochastic batch-sizing problem (SBSP). One version adopts a recourse formulation, and the other is...

In the United States, racial disparities in kidney transplantation are large and especially stark for living donor transplants. Medical researchers frequently attribute this to the availability of medically compatible living kidney donors, who are usually kin. This paper evaluates this...

Organ exchanges are expected to increase the utilization of living donors and to alleviate the critical shortage of organs for transplantation. The typical arrangement involves a direct exchange between two blood-type incompatible donor-candidate pairs. An alternate possibility is an indirect...

The United Network for Organ Sharing system of allocating cadaveric kidneys for transplantation permits only minimal involvement of patients in the selection process. The system ignores potential variations in the importance that patients may attach to outcomes associated with the transplant...
