The periodic Vehicle routing problem: classification and heuristic

M. Mourgaya, F. Vanderbeck (2006)

RAIRO - Operations Research

Similarity:

The Periodic Vehicle Routing Problem (PVRP) consists in assigning customer visits to vehicle routes in some periods of a time horizon so as to satisfy some service level requirements that can take the form of frequency of visit, constraint on time lag between visits, or pre-defined visit patterns. We present different variants of this problem and propose a classification. Then, we consider a model for tactical planning for which we propose a heuristic: we optimise the planning...

Economic assessment of the Champagne wine qualitative stock mecanism

Jacques Laye, Maximilien Laye (2006)

RAIRO - Operations Research

Similarity:

In the wine AOC system, the regulation of quantities performed by the professional organizations is aimed to smooth the variations of the quality of the wine due to the variations in the climate that affect the quality of the grapes. Nevertheless, this regulation could be damaging to the consumers due to the price increase resulting from the reduction of the quantities sold on the market. We propose a stochastic control model and a simulation tool able to measure the effects of...

Évaluation de la fiabilité d’un système de prévision de la demande dans le cas d’une politique de regroupement des besoins

Alice Yalaoui, Éric Châtelet, Chengbin Chu (2003)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

To establish production plans or replenishment plans, firms use forecasting systems. Such a system is composed of a forecasting method and a lot-sizing method. We propose a scheme to evaluate the reliability of such a system. This evaluation is based on the impact of demand randomness on the long run total cost. The scheme is illustrated with a system including an exponential smoothing technique for the demand forcasting and the Florian and Klein [5] method for the lot-sizing. Simulation...

L'espace des feuilletages d'un espace analytique compact

Daniel Barlet (1987)

Annales de l'institut Fourier

Similarity:

Nous construisons sur l’ensemble des feuilletages (avec singulariés) d’un espace analytique compact normal une structure analytique complexe. Dans le cas faiblement kählérien, nous montrons qu’à un point frontière de la compactification naturelle de l’espace des feuilletages est encore associé un feuilletage.
