Introduction一级标题 同上（引言）Organ transplantation is a preferable treatment for the most serious forms of end-stage diseases. In recent years,

2、 advances in medical science and technology have made solid organ transplantation an increasingly successful and common medical procedure, a literal second chance at life. Not only does it offer the best hope for complete rehabilitation, but it has also proved to be the most cost-effective of all tr

The surgical techniques involved have been mastered for half a century and are now considered as routine. The two main s

4、ources of kidneys for transplantation are deceased-donor kidneys and live-donations from family and friends. However, unfortunately, there is a considerable shortage of donor organs, compared to demands. As a matter of fact, efficient matching and allocation of organs donated has become an exigent p

5、roblem.The United Network for Organ Sharing (UNOS), as the operator of the Organ Procurement and Transplantation Network (OPTN), is responsible for transplant organ distribution in the United States. UNOS oversees the allocation of many different types of transplants, including liver, kidney, pancre

First, incoming organs are matched with waiting candidates by medical institutions considering the factors as ABO blood compatibility, t

After that, from the patients perspective, on the basis of linear regression, priority weight is defined by pondering age, disease severity, time on waiting, PRA level, and region. Applying

8、 this mechanism of ranking, we realize MWBM (Maximum Weight Bipartite-graph Matching) and SMGS (Stable Matching based on Gale-Shapley algorithm). MWBM focuses on the optimal assignment of donors following the algorithm of bipartite-graph maximum weight matching; SMGS emphasizes the process of exchan

12、正文Through the investigation of US transplantation network, we draw a general picture of the mechanism. With reference to some resources available on the website of UNOS, a flow chart (Figure 1) is developed showing the procedure of the network.Currently, the initial waiting list is composed of patie

For the first time, the patients are requested to show the correct and scientific information to the US kidney transplant network which is needed for donor-recipient matching, the ranking of patients on the waiting list, and de

Historical patients refer to registered patients whose status have changed and have an influence on the procedure. A patient

Conclusions.Our model for the optimal allocation of the donor organs is established by three modules, procurement of MD and PW, optimal assignment by MWBM model and Stable Matching of Gale-Shapley algorithm.
