The concept of “project planning” is not uniformly understood. Some authors reduce it to scheduling – determining the dates for performing schedule activities and deadlines for reaching milestones. In this paper, as Nicholas and Steyn (2008) we assume that planning is a process that...

Multiple objectives and dynamics characterize many sequential decision problems. In the paper we consider returns in partially ordered criteria space as a way of generalization of single criterion dynamic programming models to multiobjective case. In our problem evaluations of alternatives with...

<title>Abstract</title> In the paper a discrete multicriteria decision making problem under risk is considered. It is assumed that the set of alternatives consists of a finite number of elements that are explicitly described. The evaluations of alternatives with respect to criteria are represented by...

We apply the concept of free random variables to doubly correlated (Gaussian) Wishart random matrix models, appearing, for example, in a multivariate analysis of financial time series, and displaying both inter-asset cross-covariances and temporal auto-covariances. We give a comprehensive...
