Data streams (streaming data) consist of transiently observed, evolving in time, multidimensional data sequences that challenge our computational and/or inferential capabilities. In this paper we propose user friendly approaches for robust monitoring of selected properties of unconditional and...

Due to the famous Gale-Shapley Theorem we know that each classical marriage problem admits at least one stable matching. This fact inspired researchers to search for the maximum number of possible stable matchings, which is equivalent to find the minimum number of unstable matchings, among all...

We study the process, called the IEDI process, of iterated elimination of (strictly) dominated strategies and inessential players for finite strategic games. Such elimination may reduce the size of a game considerably, for example, from a game with a large number of players to one with a few...

We study a cost allocation problem under asymmetric information, and show that the ex ante incentive compatible core is non-empty. We also obtain a non-emptiness result for the incentive compatible coarse core, which is one concept of an interim core.

This paper presents a method for evaluating the risks in a situation where parameters in the calculation are expressed in the form of dependent fuzzy numbers and probability distributions. The procedure of risk estimation combines stochastic simulation with the execution of arithmetic operations...

In this paper, the analysis of the dependence structure among the selected European indices (FTSE, CAC, DAX, ATX, PX, BUX and BIST) is conducted. The main features of the financial data are studied: the asymmetry, the fat-tailedness, the variability and mutual dependence. We have fitted a regime...

Inventory routing problems (IRPs) occur where vendor managed inventory replenishment (VMI) strategies are implemented in supply chains. These problems are characterized by the presence of both transportation and inventory considerations, either as parameters or constraints. The research...

We consider an economic scenario where the government seeks to achieve a favourable balance-of-payments over a fixed planning horizon through exchange rate policy and control of the domestic interest rate. We view the dynamics of such an economy as a bounded optimal control problem where the...

The aim of the article was the analysis of the relations of the coexistence of Controlling and other management methods (Benchmarking, BPM, BPR, BSC, Competency-based Management, CRM, ERP, KM, LM, Outsourcing, Six Sigma, TQM). The complexity and dynamics of modern management systems in fact...

In this paper, we study the linear fractional multi-level programming problem and prove that an optimal solution to this problem occurs at a boundary feasible extreme point. Hence the Kth-best algorithm can be proposed to solve the problem. We also show that this property can be applied to...
