Resource loading appears in many variants in tactical (mid-term) capacity planning in multi-project environments. It develops a rough sketch of the resource usage and timing of the work packages of a portfolio of orders. The orders need to be executed within a time horizon organized into...

In this paper, we consider a new customer choice model which we call the single transition choice model. In this model, there is a universe of products and customers arrive at each product with a certain probability. If the arrived product is unavailable, then the seller can recommend a subset...

We study the computational complexity of the discrete sequential search problem with group activities, in which a set of boxes and group activities is given, and a single object is hidden in one of these boxes. The goal is to find a sequence in which the boxes are to be searched and the group...

A k-out-of-n system configuration requires that, for the overall system to be functional, at least k out of the total of n components must be working. This paper addresses the search for a least-cost diagnosis strategy for k-out-of-n systems when the individual component tests are imperfect,...
