An LP-digraph is a directed graph which consists of the vertices and edges of a polytope <i>P</i> directed by a linear function in general position. It is ...

In this paper we present a simple technique that uses background information to improve mining the frequent patterns of structured data. This technique uses ...

While recent algorithms for mining the frequent subgraphs of a database are efficient in the general case, these algorithms tend to do poorly on databases th...

This paper considers a two-level vendor managed inventory (VMI) system comprising a distribution center (DC) and a retailer. Both the DC's and the retailer...

Vendor managed inventory (VMI) takes on a new form in our case study. It occurs between a parent company and its several subsidiaries along the Yangtze Riv...

Flexibility in workforce planning is one of the best ways to respond to fluctuations of the demand. This paper proposes a flexible mixed integer linear pro...

The aim of this paper is to characterize cooperative and noncooperative advertising strategies of a licensor and licensee involved in a licensing contract ...

<p> Given a graph <i>G=(V,E)</i> with strictly positive integer weights <img src="/cgi-bin/mimetex.cgi?\omega_i"> on the vertices <img src="/cgi-bin/mimete...

This paper proposes to use local search inside filtering algorithms of combinatorial structures for which achieving a desired level of consistency is too c...

Real-world routing problems are often represented by large and complex models, and instances of realistic size are very hard to solve. In most cases one ca...

A stochastic control model is proposed as a paradigm for the design of optimal timing of greenhouse gases (GHG) emissions abatement. The resolution of unce...

A weighted multivariate signed-rank test is introduced for an analysis of multivariate clustered data. Observations in different clusters may then get diffe...

This paper deals with the stability analysis and the stabilization for the class of continuous-time systems with time-varying delay. The time delay is as...

This paper describes a new heuristic for the well-known <i>Undirected Rural Postman Problem</i>. It consists of two steps: it first constructs a partial so...

<p> This paper investigates the effects of in-store availability on price matching guarantees (PMGs). Under the simplest form of PMG implementation, a fir...

This chapter deals with the control of production systems and presents models for production and maintenance planning. The production systems are sup...

This papers deals with the tracking problem for the Markov Jump systems with external finite energy disturbance. A state feedback controller that makes the...

Cet article vise l'analyse du type de modélisation des problèmes tests utilisés par les chercheurs pour valider leurs stratégies de pilotage des systèmes d...

This paper deals with the class of linear discrete-time systems with random abrupt changes also known as class of Markovian jump singular systems. Th...

With the help of the AutoGraphiX system, we study relations of the form
