We formulate the Forest Management Problem as a Multicommodity Network Flow Problem with a convex cost function. We then show how to transfer the problem to an equivalent Single-Commodity Network Flow formulation in order to address several sensitivity analysis questions using results by Granot...

We discuss in this paper some inventory-production models which can be formulated as nonlinear parametric network flow problems with one additional linear constraint. Several sensitivity analysis questions are addressed. The qualitative sensitivity results obtained provide the manager with...

This paper proposes a methodology for evaluating and selecting R&D projects in a collective decision setting, especially useful at sectorial and national levels. It consists of two major phases: Evaluation and Selection. The evaluation process repeatedly uses mathematical programming models to...
