>
> Blood plays a crucial role in all health care systems, it is a limited
> resource and its shelf life is short. In Western countries, blood is
> collected from donors, and the so-called Blood Donation Supply Chain (BDSC)
> aims to provide an adequate supply of blood units to transfusion centers
> and hospitals.
> In this talk, I focus on the collection of blood units from donors, which
> is the first BDSC echelon, and I consider two opposing donation settings:
> the classical blood donation at the collection center, and a new
> organizational model in which blood is collected at donor’s homes to
> respond to the emerging need for delocalization of health services. For
> each of them, I tackle the Blood Donation Appointment Scheduling (BDAS)
> problem, providing a decision support tool that balances the production of
> the different blood types between days in order to provide a fairly
> constant supply of blood units to the rest of the BDSC.
> In the case of donations at the collection center, the tool consists of an
> offline Mixed Integer Linear Programming (MILP) model that preallocates
> time slots to blood types, and an online prioritization policy that assigns
> a preallocated slot when the donor calls to make the reservation. In the
> case of home blood donation, the tool consists of a matheuristic framework
> with three decision stages, in which the first two stages extend those of
> the other setting and the third one consists of a Multi-Trip Vehicle
> Routing Problem with Time Windows to route the bloodmobiles that collect
> blood at donors’ homes.
> Both tools have been tested on data coming from a real Italian provider,
> i.e., the Milan department of the Associazione Volontari Italiani Sangue
> (AVIS). The numerical experiments have verified the well-performing
> behavior of both frameworks. In particular, the tests conducted on
> realistic instances generated based on the AVIS Milan case have confirmed
> the capability of the tools to balance the production of each blood type
> over the days and, for home blood donation, to create cost-effective
> vehicle schedules.
