We determine the optimal timing for replacement of an emerging technology facing uncertainty in both the output price and the arrival of new versions. Via a sequential investment framework, we determine the value of the investment opportunity, the value of the project, and the optimal investment...

In the last few decades, several effective algorithms for solving the resource-constrained project scheduling problem have been proposed. However, the challenging nature of this problem, summarised in its strongly NP-hard status, restricts the effectiveness of exact optimisation to relatively...

The goal of this article is to survey the relevant literature on project scheduling with possible activity failures from a number of different disciplines, and to distill from these sources the formulation of a general optimization problem, the further study of which we would like to foster...

We develop a multistakeholder, multicriteria decision-making framework for Eurocontrol, the European air traffic management organization, for evaluating and selecting operational improvements to the air traffic management system. The selected set of improvements will form the master plan of the...
