Nested Models Implemented in Nested Theories

Professor Eugene Kindler Faculty of Science

University of Ostrava Street 30. dubna 22, CZ - 701 03 Ostrava

CZECH REPUBLIC E-mail: ekindler@centrum.cz

Abstract: Systems developed with human influence are often facilitated by sophisticated information processing components that influence the behavior of the system itself. They can be automatic control automata and/or humans. When it is necessary exactly to model such systems (e.g. for their analysis but especially for their simulation) the desire is to have a tool for their exact describing, with a possibility to use the description in further phases of the work (namely for implementing simulation models) but also for readable communication on the concerned system with other engaged persons. Problems rise in case the described system has an information processing unit that handles an internal model of a certain system which would demand the same tool. This system can be similar to the whole system or not. Examples of the spectrum illustrating that (non-)similarity will be given. The solution consists in building formal theories in that elements occur that are carriers of other formal theories. These "local" formal theories may use some information of the "world" in that their carriers occur, i.e. may point out from them and penetrate to the formal theory used for describing the system in that the carriers occur and that can be influenced by those carriers. In case we desire to have tools suitable applicable for implementing computer models, the formal theories can be suitable formulated in object-oriented programming languages that are also block-oriented and agent-oriented. The characteristics of such languages that would distinguish them from "poor" programming tools will be presented, together with applications in logistics, production, graphics and environmental science. Brief Biography of the Speaker: Eugene Kindler was born in 1935, studied mathematics at Charles University in Prague, (Czechoslovakia) and then computer science at the Research Institute of Mathematical Machines in Prague. He is the author of the first Czechoslovak ALGOL 60 compiler and the first Czechoslovak simulation language and compiler (COSMO, Compartmental System Modeling). Charles University granted him PhDr in logic and RNDr (Rerum Naturalium Doctor) in the theory of programming, Czechoslovak Academy of Science granted him CSc (Candidate of Sciences) in mathematics and physics. During 1958-1966 he worked with the Research Institute of Mathematical Machines, then with the Institute of Biophysics of the Faculty of General Medicine of Charles University (until 1973) and then with the Faculty of Mathematics and Physics of the same University (until 2006). In parallel, he engaged as professor of applied mathematics at a new University of Ostrava (Czech Republic) and was guest professor at the universities of Italian Pisa, American Morgantown and French Clermont-Ferrand and Lorient. Since 2006 he has been pensioned, collaborating with the same Ostrava University as external specialist in various research projects, in doctoral studies and with a rather new Faculty of art. Beside his official work in computer science, he applied exact techniques (applied in programming language analysis) to formulate the rhythmical laws of music in free rhythm and is a director and soloist of singing group Musica Poetica specialized to the chant originated during the first millennium A.D. in Europe and certain Near East Asian countries.

Plenary Lecture 2

Discrete Event Formalisms for Workflow throughput Diagnose

Associate Professor Calin I. Ciufudean "Stefan Cel Mare" Universtity of Suceava

Faculty of Electrical Engineering and Computer Science Department of Automatics and Computers

9, University str., RO720225, Suceava ROMANIA

E-mail: ciufudean.calin@yahoo.com Abstract: We focus on estimating the throughput of a workflow modelled with stochastic Petri nets (SPNs). We consider this discussion important, as there is a lot of confusion about the definition of the risk and the reliability of flexible manufacturing system analysis, both being risk analysts and decision makers. We propose an approach for this analysis by using a new model for artificial social systems (ASSs) behaviours, and by introducing equivalent transfer functions for SPNs. ASSs exist in practically every multi-agent system, and play a major role in the performance and effectiveness chart of the agents. ASS allows agents to coexist in a shared environment and pursue their respective goals in the presence of other agents. This is the reason why we introduce a suggestive model for ASSs. To model complex systems, such as flexible manufacturing ones, a class of Petri nets is adopted, and briefly introduced. This class allows representing the flow of physical resources and control information data of the ASSs components. In the analysis of SPN we use simulations in respect to timing parameters in a generalized semi-Markov process (GSMP). By using existing results on perturbation analysis (e.g., delays in supply with raw materials, equipment failure, etc.), and by extending them to new physical interpretations we address unbiased sensitivity estimators correlated with practical solutions in order to attenuate the perturbations. The novelty of the approach is that the construction of large Markov chains is not required. Using a structural decomposition, the construction system is divided into cells. We can simplify the structure of the SPN using the presented approach, which is useful when we deal with complex Petri nets, and we need to simplify these structures (e.g. graphs) in order to analyze them properly. For each cell a Markov model was derived and the probability was determined of at least Ni working machines in cell i, for i = 1, 2, .., n and j, where j = 1, ..., m, working material handling system (MHS) at time t, where Ni and j satisfy the system production capacity requirements. An example illustrates this approach. The results reported here form the basis of several enhancements, such as conducting performance studies of complex systems with multiple part types.

How to Investigate the Decision Making Behavior of Investors in Financial Markets by means of Software Agents

Professor Filippo Neri Universita' di Napoli "Federico II"

Dipartimento di Informatica e Sistemistica Via Claudio 21

80125 Napoli (NA) ITALY

E-mail: filipponeri@yahoo.com Abstract: Financial markets are an example of complex systems where relevant behavior happens to be a synthesis of independent and singular decisions taken by individual entities operating in them. Such is the case of financial markets where several investors autonomously decide what investment decision to undertake. In our work, in particular, we focus our attention to the following research question: can a software agent simulation reproduce the behaviour of a significant financial market time serie by concentrating on many simple interactions among investors-agents. This talk takes forward a research line we started to investigate a year ago and the most promising empirical findings are reported. Brief Biography of the Speaker: Prof. Filippo Neri is currently a professor in Computer Science at the Department of Computer and System Science of University of Naples "Federico II". Prof. Filippo Neri has wide experience in the area of artificial intelligence, machine learning, and software agent simulation.

He has studied and visited at several important academic institutions including Carnegie Mellon University, MIT, Imperial College London, University of Milano, University of Torino. He is a Marie Curie Fellow and an ADI associate, the Italian PhD association. He is a founding member of initiatives aiming to close the gap between academia and the business application of research results. Finally he has served in the program committees and as reviewer at several international conferences and he is author of more than 50 internationally reviewed publications.

Plenary Lecture 4

Improving Monitoring, Control and Protection of Power Grid Using Wide Area Synchro-Phasor Measurements

Professor Hamid Bentarzi DGEE, FSI, Boumerdes University

ALGERIA E-mail: bentarzi_hamid@yahoo.com

Abstract: When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the overall power grid disturbances and then they are not able to avoid the blackout. The introduction of the advanced measurement and communication technologies in these systems may provide better ways to detect rapidly these disturbances and protect the overall grid from the propagation of the fast-cascading outages. Indeed, the observability of the wide area power system dynamics becomes feasible through the use of these recent developed technologies. Using wide area real-time synchro-phasor measurement system based on Phasor Measurement Units (PMUs), different types of wide area protection, emergency control and optimization systems can be designed and implemented. In this talk we discuss new technologies that allow wide area grid to be well monitored, controlled and protected against any disturbances. At the beginning, we present the different steps which may be followed in order to develop PMU based Wide area measurement system taking into count quality of the power grid dynamics observability. After that, we discuss how to improve monitoring, control and protection integrated system for wide area power grid. We have already designed and implemented PMU based wide area synchro-phasor measurement system through the use of the new technologies as well as we have tested its performances for showing its experimental evaluation. Besides, we have developed some applications where these advanced technologies have been used. We will end up this talk by presenting our research work results related to this subject.

Plenary Lecture 6

Method for Classification in Interval-Valued Information Systems

Professor Amaury A. Caballero Department of Electrical and Computer Engineering

Florida International University 10555 W. Flagler Street

Miami, Florida USA

E-mail: caballer@fiu.edu Abstract: Due to its importance in a number of fields, the problem of classification or classes discrimination in information systems has been approached by multiple authors, and various methods to address this issue have been developed. The combination of rough sets and fuzzy logic for classification is a widely adopted method. Rough set theory helps in minimizing the number of attributes that influence the selection and fuzzy logic permits to discriminate when there is more than one possible solution for the same attributes and intervals. Neural networks and information entropy have also been used to discriminate. When information is diffuse and the number of obtained values for each attribute is large, such is the number of rules for any type of solution method. Due to this fact, interval-valued information systems have been proposed by several authors, in which an interval of values is defined for each attribute, moving from the minimum to the maximum obtained values in the database or using the standard deviation from the original data to define the minimum and maximum values. Differently from other works, the concept of information measure is used in this paper, together with a fuzzy logic discrimination tool. Using these concepts, an attribute reduction is initially obtained and then fuzzy logic is applied for discriminating among the possible solutions. The method results simpler than others, and as accurate as the methods usually employed. Brief Biography of the Speaker: Amaury A. Caballero obtained his Bachelor Degree in Electrical Engineering from the University of Havana, Cuba, earned his Ph.D. in Technical Cybernetics from the Energy Institute of Moscow, Russia, and his Professional Engineer License from the state of Florida, USA.
