Generating multivariate Poisson random variables is essential in many applications, such as multi echelon supply chain systems, multi-item / multi-period pricing models, accident monitoring systems, etc. Current simulation methods suffer from limitations ranging from computational complexity to...

Uncertainty is a fundamental property of networks which evolve continually due to varying demand and capacity. The characterization of the stochasticity with scenario-based approaches has emerged as a promising method to systematically incorporate variability. Under this paradigm, each scenario...

Proposing a full ranking method to rank all the homogeneous decision-making units (DMUs) is one of the important issues … in data envelopment analysis (DEA) field. It should be noted that one of the main challenges in using traditional ranking … this paper, the novel ranking method for DMUs under uncertain environment is presented. using DEA method, super efficiency …

Orderings of interdependence among random variables are useful in many economic contexts, for example, in assessing ex post inequality under uncertainty; in comparing multidimensional inequality; in valuing portfolios of assets or insurance policies; and in assessing systemic risk. We explore...

This paper generalizes the locally optimal linear rank test based on copula from Shirahata (1974) resp. Guillén and Isabel (1998) and Genest et al. (2006) to p dimensions and introduces a new X2-type test for global independence (Nelsen test). The test is compared to similar nonparametric tests...
