Model-based Decision Support Systems (DSS) often use multi-criteria optimization for selecting Pareto-optimal solutions. Such a selection is based on the interactive specification of user preferences. This can be done by a specification of aspiration and reservation levels for criteria. Diverse graphical user interfaces can be used for specification of(More)
Robustness or insensitivity is a desirable property of decisions; however, most texts on robustness and/or sensitivity analysis do not de ̄ne it precisely. A broad literature in this ̄eld concentrates on robust design of decisions (including robust optimization). This paper focuses on robustness testing, that is, checking whether a design has actually(More)
In this paper we will present a framework for modeling and management of complex systems. There are various approaches for modeling of these systems. One of the approaches is events driven modeling and management of complex system. Such approach is needed in information systems that provide information in real-time. Most of the existing modeling approaches(More)
The paper presents the management system of the IPv6 QoS Parallel Internet. The IPv6 QoS Parallel Internet has been developed as a part of the IIP System, which is the result of the project “Future Internet Engineering”. The architecture of the IIP System applies virtualization concept for supporting a number of Parallel Internets while using(More)
