Project risks have never been so present. First, projects are dealing with bigger stakes and facing stronger constraints. Moreover, projects must cope with an ever-growing complexity. Risks have then increased in number and criticality. Lists of identified project risks thus need to be...

Many cases of externalities in agricultural production such as pesticide drift, cross-pollination, and offensive odors are attributable to the incompatibility of neighboring land uses. This paper offers an examination of when an efficient activity arrangement is compatible with free-market...

Given G = (V, E) a connected undirected graph and a positive integer β(|V|), the vertex separator problem is to find a partition of V into no-empty three classes A, B, C such that there is no edge between A and B, max{|A|, |B|} ≤ β(|V|) and |C| is minimum. In this paper we consider the...

We investigate the problem of partitioning the nodes of a graph under capacity restriction on the sum of the node weights in each subset of the partition. The objective is to minimize the sum of the costs of the edges between the subsets of the partition. This problem has a variety of...
