The vehicle routing problem with time windows (VRPTW) consists of finding least-cost vehicle routes to satisfy the demands of customers that can be visited...

Variable neighborhood search (VNS) is a framework for building heuristics, based upon systematic changes of neighborhoods both in a descent phase, to find a...

In this paper, we investigate team optimal control of a population of heterogeneous LQ (Linear Quadratic) agents. The population consists of finite distinct...

Cet article traite la prise en compte d'incertitudes lors de la résolution de conflits. Plus particulièrement, nous considérons les incertitudes dues aux err...

Nous présentons un modèle déterministe pour le problème de détection et de résolution de conflits entre aéronefs. Les aspects liés à la dynamique des avions,...

We consider a multi-agent system with linear stochastic individual dynamics, and individual linear quadratic ergodic cost functions. The agents partially o...

Decentralized sequential hypothesis testing refers to a generalization of Wald's sequential hypothesis testing setup in which multiple decision makers make ...

Given a complete directed graph \(G\) with weights on the vertices and on the arcs, a \(\theta\)-improper \(k\)-coloring is an assignment of at most `...

The fundamental limits of remote estimation of Markov processes under communication constraints are presented. The remote estimation system consists of a sen...

In this paper we propose a general variable neighborhood search heuristic for solving the uncapacitated single allocation p-hub center problem (USApHCP). F...

The uncapacitated multiple allocation p-hub center problem (UMApHCP) consists of choosing p hub locations from a set of nodes with pairwise traffic deman...

Usually several neighborhood structures may be explored within a single local search algorithm. The simplest way is to define a single neighborhood as a unio...

In this paper we investigate the options of a network operator faced with the requirement of reducing its carbon footprint, expressed in terms of a global en...

In the present paper, we are interested in bounding differences between graph invariants as well as in characterizing the corresponding extremal graphs. This...

This paper proposes an incentive mechansim for transmission expansion planning. The mechansim is a bilevel program. The upper level is a profit-maximizing tr...

Robust optimization (RO) is a powerful mean to handle optimization problems where there is a set of parameters that are uncertain. The effectiveness of the m...

Studies of traffic dynamics rely either on macroscopic models considering the traffic as a fluid, or on microscopic models of drivers' behavior. The connec...

The problem of optimal real-time transmission of a Markov source under constraints on the expected number of transmissions is considered, both for the discou...

The packet delay variation, commonly called delay jitter, is an important quality of service parameter in IP networks especially for real-time applications. ...

Jitter buffering is a key component in multimedia and real-time services. A jitter buffer is used at the receiver side to control packet rate and to compensa...
