We study the two-staged fixed orientation constrained two-dimensional two-staged cutting stock problem. We solve the problem using several approximate algorithms, that are mainly based upon a strip generation procedure (HESGA) already developed in ([13)]. We evaluate the performance of these...

The basic Vehicle Routing and Scheduling Problem (VRSP) is described followed by an outline of solution approaches. Different variations of the basic VRSP are examined that involve the consideration of additional constraints or other changes in the structure of the appropriate model. An...

The purpose of this paper is to introduce the area of Green Logistics and to describe some of the problems that arise in this subject which can be formulated as combinatorial optimization problems. The paper particularly considers the topics of reverse logistics, waste management and vehicle...

The purpose of this article is to present a novel method to approximately solve the Multiple-Scenario Max-Min Knapsack Problem (MSM2KP). This problem models many real world situations, e.g. when for many scenarios noted $\pi \in \mathcal P=\{1,\ldots,P\}$, the aim is to identify the one offering...

In cooperative game theory, the Shapley value is a central notion defining a rational way to share the total worth of a game among players. In this paper, we address a general framework, namely regular set systems, where the set of feasible coalitions forms a poset where all maximal chains have...

This research takes an interest to the gap between employment and education of young people in the survey Generation 98 of Cereq. This research compares the positions of young people who are recruited on jobs with classic status and subsidised jobs. A lot of people are downgrading because their...

The positive effect of a common currency on trade is empirically well-documented, but the reason of this effect remains unclear. In this paper, we argue that part of the currency union effect on trade is indirect. Currency unions foster foreign direct investment (FDI), which promotes trade due...

We consider a class of pure exchange economies with externalities. The consumption set and the preferences of each household depend on his initial endowment and on the actions of the other households. We give a definition of competitive equilibrium with externalities which includes as particular...

This document starts from the statement that all human resources themes can generate risks of inequalities and discrimination between men and women. Of course, these discriminations are indirect but the results is the same about recrutment, careers, wages, balance between family life and work,...

This article aims at testing the convergence hypothesis in MENA region using new tests of a unit root in panel data. Quah (1994, 1998), Evans & Karras (1996) and Bertrand & Jones (1996) recommend this technique to evaluate the income convergence hypothesis. According to them it avoids...
