The development of truck dispatching systems has during recent years taken two directions. One has been systems using mathematical optimization and powerfu...

In this paper we develop a stochastic, dynamic network equilibrium model of airline passenger transportation. The model explicitly incorporates the behavior...

CREW-OPT is a new software module in the HASTUS family of scheduling software. CREW-OPT produces optimal or near-optimal crew schedules for small problems (...

Le problème classique de dimensionnement d'un réseau de télécommunications se formule en général comme suit: étant donné un réseau, une matrice de trafic et...

The problem we consider is that of preparing a minimum cost transportation plan by simultaneously solving the following two sub-problems: first the assignm...

This paper presents a model for the optimization of productivity in a steel plant comprised of four arc furnaces and three continuous casting machines and su...

The two-dimensional cutting-stock problem consists of laying out a specified list of rectangular pieces on rectangular sheets, in such a way as to minimize t...

The vehicle routing problem (VRP) involves the design of a set of minimum cost routes for a fleet of vehicles which services exactly once a set of customers...

Schedule compression is a major concern in project management. We propose an extension of the classical crashing model to include the managerial practice of...

We consider projects represented by a PERT network, with convex cost-of-time functions on individual activities, and we show the existence of an efficient m...

The multiple vehicle many-to-many routing problem is presented in the context of a dial-a-ride system. It is solved by mini-clustering first and optimal ro...

We present an algorithm that solves the problem of finding the vehicle schedule which minimizes total inconveniences for travel along a fixed path, where se...

Le problème classique d'optimisation de la capacité des réseaux de télécommunications s'énonce comme suit: pour un réseau dont la structure, la demande et l...

Several single-commodity, two-commodity and multi-commodity flow formulations have recently been introduced for the travelling salesman problem. The purpose...

We present a dual algorithm to minimize a separable convex function under ratio constraints between variables. This minimization problem occurs when the dep...

The problem is to elaborate a minimum cost transportation plan by simultaneously solving the following two sub-problems: the assignment of available units at...

We present an algorithm that solve the problem of finding the best vehicle time schedule (minimizing total inconveniences) for a fixed path, knowing that vis...

We propose a measure of the reliability of a telecommunication network based on the expected value of the lost call traffic due to failures in the network. ...

The urban transit crew scheduling problem arises in mass transit corporations who have to create minimal cost bus driver schedule respecting both the collect...

This paper presents mathematical formulations for some vehicle routing and scheduling problems with time window constraints and the optimal solution approach...
