The purpose of this paper is to introduce a new way of choosing directions for the Mesh Adaptive Direct Search (MADS) class of algorithms. The advantages of...

Portmanteau test statistics represent useful diagnostic tools for checking the adequacy of multivariate time series models. For stationary and partially non-...

We describe LANCELOT_simple, an interface to the LANCELOT B nonlinear optimization package within the GALAHAD library (Gould, Orban and Toint, 2003) which ig...

This paper analyzes competition between mutual funds in a multiple funds version of the model of Hugonnier and Kaniel [18]. We characterize the set of equili...

This paper describes a class of large-scale capacity planning problems under uncertainty. The uncertainty can arise in different dimensions of a production...

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...
