In this paper, we address the issue of optimal selection of portfolio of projects using reinvestment strategy within a flexible time horizon. We assume that an investor intends to invest his/her initial capital on the implementation of some projects in a flexible time horizon. The investor’s...

It is generally accepted that the three major dimensions of project success are time, budget, and quality. Most of the research in project planning is focused on the time-cost trade-off, and only a few papers have considered the three dimensions together. This paper describes the evolution of...

In this paper we propose an adaptive model for multi-mode project scheduling under uncertainty. We assume that there is a due date for concluding the project and a tardiness penalty for failing to meet this due date, and that several distinct modes may be used to undertake each activity. We...

We consider a model of Paired Kidney Exchange (PKE) with feasibility constraints on the number of patient-donor pairs involved in exchanges. Patients' preferences are restricted so that patients prefer kidneys from compatible younger donors to kidneys from older donors. In this framework,...

We consider collective decision problems given by a profile of single-peakedpreferences defined over the real line and a set of pure public facilities to be located on the line. In this context, Bochet and Gordon (2012) provide a large class of priority rules based on efficiency,...

Standardized and transparent priority setting in medicine, desirable as it is, will generally exacerbate inter-temporal equity problems arising from changes in treatment priorities: when can it be fair that the treatment of already waiting patients who would have had priority under an...
