Analysis and simulation of the Bullwhip Effect in a supply chain

One of the most important problems in the coordination of the entire supply chain comes from the fact that the whole system, working on the basis of a future prediction, is strongly affected by unexpected changes in external demand and even small changes can lead to huge distortions in the…

Experimenting an Artificial Bee Colony algorithm to approach the capacitated vehicle routing problem

ThŒis paper is focused on the comparison of results obtained by the resolution of the capacitated vehicle routing problem. A modi€ed algorithm of classical arti€cial bee colony (ABC) is described and implemented in this article, in particular, a new type of neighborhood operator is introduced. Œe…

Weighted polynomial approximation on the square by de la Vallée Poussin means

We consider the generalization of discrete de la Vallée Poussin means on the square, obtained via tensor product by the univariate case. Pros and cons of such a kind of filtered approximation are discussed. In particular, under simple, we get near-best discrete approximation polynomials in the…

Qualitative analysis and numerical approximation of an optimal control model for invasivespecies

Invasive species cause huge amounts of environmental, economic, social and cultural damage in Europe and worldwide. Improving measures to control them is an ongoing challenge, and mathematical modeling and optimization are becoming increasingly popular as a tool to assist management (1; 2; 4). We…

Polluted porous media biological decontamination

Some kind of pollutant, particularly hydrocarbon, can be removed from the polluted subsoil by means of micro organism activity. Oxygen is required during the biodegradation process and therefore air is injected in the subsoil. A multiphase and multicomponent mathematical model describing the…
