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...

We study the number \({\cal{P}}(G)\) of non-equivalent ways of coloring a given graph \(G\). We show some similarities and differences between this graph...

Many important NP-hard combinatorial problems can be efficiently approximated using semidefinite programming relaxations. We propose a new hierarchy of sem...

This article deals with the general theory of games played over uncontrolled event trees, i.e., games where the transition from one node to another is natu...

It is increasingly important to provide the relevant data for strategic decisions related to oil production and the marketing of oil products. We propose the...

<b>Background:</b> Zoonoses are a growing international threat interacting at the human-animal-environment interface and call for transdisciplinary and mul...
