We consider the problem of orienting the edges of a graph so that the length of a longest path in the resulting digraph is minimum. As shown by Gallai, Roy ...

In this paper, we consider scheduling problems on a single machine in a sequence dependent setup environment. We introduce for these problems several integer...

The Cox proportional hazards model has become the model of choice to use in analyzing the effects of covariates on survival data. However, this assumption ha...

In this paper, we study the problem of determining the capacity requirements for applications that require QoS guarantees. We consider three kinds of source ...

This work shows how disjunctive cuts can be generated for a bilevel linear programming problem (<i>BLP</i>) with continuous variables. First, a brief summar...

Given buses of different types arriving at a depot during the evening, the bus parking problem consists of assigning these buses to parking slots in such a w...

We consider test statistics for autoregressive conditional heteroskedasticity (ARCH) in the residuals from a possibly nonlinear and dynamic multivariate regr...

We consider two overlapping generations that want to coordinate their strategies of working, consuming and controlling pollution. As the cooperative solution...

In this paper, we model a two-period electricity market with interrelated demand, where oligopolistic generators make investments in peak- and base-load capa...

Let <img src="/cgi-bin/mimetex.cgi?G = (V,E,w)"> be a graph with vertex and edge sets <img src="/cgi-bin/mimetex.cgi?V"> and <img src="/cgi-bin/mimetex.cgi?E...

This paper considers large shift scheduling problems with different shift start times and lengths, fractionable breaks and work stretch duration restrictions...

We address a multi-objective version of the car sequencing problem, which consists in sequencing a given set of cars to be produced in a single day, minimizi...

We consider the problem of locating a circle with respect to existing facilities on the plane, such that the largest weighted distance between the circle and...

Consider a convex polygon <i>V_n</i> with <i>n</i> sides, perimeter <i>P_n</i>, diameter <i>D_n</i>, area <i>A_n</i>,...

This paper deals with the class of linear discrete-time systems with varying time-delay. The problems of stability and stabilizability for this class of syst...

Quel octogone de diamère unité (ou petit octogone) possède la plus grande surface ou le plus grand périmètre? Serait-ce l'octogone régulier? Eh! non, il n'en...

In this paper, we study the quasi-likelihood estimator of the drift parameter <img src="/cgi-bin/mimetex.cgi?\theta"> in the Ornstein-Uhlenbeck diffusion pr...

In this article we consider the problem of assigning parking slots to buses of different types so that the required buses can be dispatched easily in the mo...

We analyze a territorial approach to deliver nursing home care services to a territory public health. We present the case of the CSSS assigned to Côte-des-N...

The objective of the project is to provide dynamic scheduling solutions to two different services, automobile dealerships and dental clinics, in order to hel...
