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...

This article considers the normal form in logic. Any propositional function, i.e. any finite logical expression, can be written in such a form. This indicates the possibility of an unequivocal logical representation of many different objects investigated in science and everyday life. The...

Description of the papers presented in 2014/Vol. 24/No. 4

We investigate the characteristics of price patterns in an oligopoly market with costs for switching a provider. We consider two regimes of a company’s access to information. In the benchmark scenario, firms make decisions based on perfect information about demand. In the second –...

When determining a group ranking, the information about experts’ opinions may be sometimes incomplete. In such cases, usually only the outranking matrix L or the majority margin matrix is available. Debord [2] presented a technique for constructing the set of experts’ opinions...

The main objective of this article was to develop a graphical presentation of a measure of an employee’s competence (ECVM) for a job position. In this context, the paper presents the essence and formula for measuring the value of an employee’s competences. This formula makes it...

This paper presents a new approach to modeling the variability of power generation from a renewable source such as wind or flowing water. The force of the power generating agent is assumed to change according to a semi-Markov process with finite state space. For the purpose of its construction,...
