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...

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

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...

The problems of definition

Similarity:

The aim of this paper is to present the great kinds of definitions known in mathematical logic, their goals and their means, from their historical and philosophical background (notably thanks to the proof of two theorems), and in order to situate, within this field, the others contributions which make up this number.
