Recent data confirms that the power consumption of the ICT and of the Internet itself can no longer be ignored considering the increasing pervasiveness and...

A robust multi-period model is proposed to minimize the energy consumption of IP networks, while guaranteeing the satisfaction of uncertain traffic demands. ...

Despite the growing concern for the energy consumption of the Internet, green strategies for network and traffic management cannot undermine the quality and ...

In this paper we present JNetMan, a new Java framework for rapid development of network management solutions based on SNMP (Simple Network Management Protoco...

The analysis of networks and in particular the identification of communities, or clusters, is a topic of active research with application arising in many dom...

The frontier of the Production Possibility Set (PPS) consists of two types of full dimensional facets; efficient and weak facets. Identification of all facet...

Since its inception, stochastic Data Envelopment Analysis (DEA) has found many applications. The approach commonly taken in stochastic DEA is via chance cons...

In this paper, we propose a multivariate random forest method for multiple responses of mixed types with missing responses. Imputation is performed for eac...

This paper considers inventory models of <i>(Q,s)</i> type with <i>Q</i> the order-quantity and <i>s</i> the order point. In general, an optimal choice of c...

Generation Expansion Planning (GEP) with load uncertainty is modeled in this paper using chance constrained programming, and new iterative solution algorit...

In this paper, we establish closed-form formulas for key probabilistic properties of the cone-constrained optimal mean-variance strategy, in a continuous mar...

In this work, we study the goal-achieving probabilities of a multiperiod mean-variance financial strategy under a switch-when-safe stopping time rule. Th...

Aircraft maintenance planning is of critical importance to the safe and efficient operations of an airline. It is common to solve the aircraft routing and ma...

We consider a class of dynamic games played over an event tree, where the players cooperate to optimize their expected joint payoff. Assuming that the pla...

We propose a generalization of the limited-memory Cholesky factorization of Lin and Moré (1999) to the symmetric indefinite case with special interest in sym...

In this paper, we present a mixed integer programming model for solving the long-term planning problem of an underground mine. This model establishes the seq...

In 1971, Graham and Pollack established a relationship between the number of negative eigenvalues of the distance matrix and the addressing problem in data c...

In this paper we present a forecasting method for time series using copula-based models for multivariate time series. We study how the performance of the p...

Variations and extensions of the basic vertex-colouring and edge-colouring models have been developed to deal with increasingly complex scheduling problems. ...

A graph \(G = (V,E)\) is \(r\)-equitably \(k\)-colorable if there exists a partition of \(V\) into \(k\) independent sets `(V1, V2, \ldots, V_k...
