ROMSIM has been founded in 1990 as a non-profit society, devoted to both theoretical and applied aspects of modelling and simulation of systems.

General Information

ROMSIM currently has about 100 members from both Romania and Republic of Moldavia. The main objectives of ROMSIM are: development of new methods and instruments of modelling and simulation of systems, development of new application of modelling and simulation of both natural systems and those created by man, development of education and training in the field of modelling and simulation of systems. Another important objective of ROMSIM is organization of national scientific events in the field of modelling and simula-tion and participation at international conferences. In April 1999 ROMSIM has been ac-cepted as an observer member of EUROSIM.

Past Events

ROMSIM has developed in the last time a lot of activities in both scientific and information field, as for instance: organization of scientific conferences and seminaries in modwelling and simulation of systems, information of ROMSIM members on international conferences aso. ROMSIM helped the organization of the 9^th IFAC/IFORS/IMACS/IFIP Symposium on Large Scale Systems: Theory and Applications, held in Bucharest in July 2001. Several members of ROMSIM presented communications in the frame of this Symposium and/or chaired Technical Sessions. Several ROMSIM members presented communications at CSCS-13^th International Conference on Control Systems and Computer Science, held in Bu-charest in May 2001. Some ROMSIM members attended ECC-European Control Confer-ence, held in Porto, Portugal, in September 2001.

Others ROMSIM members developed activities in the frame of 15th IFAC World Congress, Barcelona, Spain 2002; several members of ROMSIM presented scientific communications.

Taking into account the prestige of IFAC-International Federation of Automatic Control, the acceptance of some papers of ROMSIM members to be included in the program of the IFAC Congress can be seen as a success. A member of ROMSIM has participated at MATHMOD Conference 2003 organized at TU Vienna.

An important future activity of some ROMSIM members developed activities in the frame of 15th IFAC World Congress to be held in Barcelona, Spain and where several members of ROMSIM presented scientific communications. Taking into account the prestige

At the demand of Prof. Yskandar Hamam, EUROSIM President, a ROMSIM member was proposed for international programme committee of BioMedSim03 conference.

An editorial event to be mentioned is the editing of a Special Issue of the Journal Studies in Informatics and Control by a team of ROMSIM. The Special Issue was dedicated to Fuzzy Systems and Logic: Theory and Applications in Simulation and Control and the Editors of the Special Issue have been Prof. Paul Flondor and Dr. Mircea Sularia.

ROMSIM is involved in organization of the Eurosim Congress 2007 to be hold in Liubliana. Four members of ROMSIM have been proposed to be members of the International Program Committee of the Congress.

At the same time ROMSIM encouraged members to prepare and submit papers at this Con-gress. As a result we expect to have a representative participation to Eurosim Congress 2007.

Two members of ROMSIM will attend the MATHMOD Conference to be hold in Vienna in February 2007. ROMSIM will be represented at the Eurosim Board Meeting, to be hold in February 11, 2006 in Vienna.

ROMSIM is involved in organization of the periodic scientific seminary titled Fuzzy Sys-tems and Fuzzy Logic; 15 to 20 specialists attend the reunion of the seminary.

The seminary present and discuss both theoretical and applied contributions of participants, in the field of fuzzy sets, fuzzy logic and fuzzy systems. We emphasize that the founder of this seminary was the well-known fuzzy expert Prof. C. V. Negoita.

We emphasize also the activity of ROMSIM members in the field of publishing books, monographs and articles in international and/or Romanian journals. Some monographs are to be published in a new Series titled Technologies of Information, of Technical Publishing House, Bucharest and articles will be published in the Romanian journals SIC-Studies in Information and Control and RRIA-Romanian Journals of Informatics and Automatics. ROM-SIM members ensure the reviewing of articles submit by authors to Editorial Staff of these journals.

The Seminar on "Fuzzy sets, theory andapplications" started working in 1996. Since then the activity of the seminar has taken place at thInstutute of Informatics in Bucarest. The main fields of interest are: fuzzy setstheory, fuzzy logic and various applications in model ing, optimization and fuzzy systems.

The seminar is in fact an interdisciplinary one;there are mathematicians, computer science engineers, economists and logicians trying to apply fuzzy technics.

Many other subjects werec onsidered: modal logic,causality, machine learning neural nets, large systemsetc.The activity of the seminar was reported in"Studies in information and control" (in 1997, 1998, 1999, 2000).

In this very moment (the spring 2003) the seminaris concentrated on dynamic logic and representationsof fuzzy structures. The leader of the Seminary is Prof. Paul Flondor.

At the same time ROMSIM members are interested to attend the 5th International EUROSIM 2004 Congress, which will take place in Paris. ROMSIM encourages some members to pre-pare tutorials and/or scientific communications to be presented at EUROSIM 2004 Con-gress.

Two editorial events must be emphasised. The first is the publication (in 2003) of the book entitled "Modelarea Sistemelor de Mare Complexitate" (Modelling of High Complexity Sys-tems) printed by the Publishing House Editura Tehnica Bucharest, in Romanian with the contents and an abstract in English. We mention that this book has received the prix "Grigore Moisil" of Romanian Academy (see www.academiaromana.ro). The second is the publication (May 2005) of the book entitled: Modelling of High Complexity Systems with Applications (including a CD with 12 MathCAD applications and a Readme) printed by the English Publishing House WIT Press, Southampton, Boston.

Both book have the same author: dr. Florin Stanciulescu.

At the same time members of ROMSIM have published articles in Romania Journal for Informatics and Automatics, as Dr. Florin Hartescu, Dr. Zoe Radulescu and other.

Starting with october 2002, at the Faculty of Automatics and Computer Science of the Politehnica University of Bucarest, a monthly seminar about chaos, fractals and applications takes place. About 30 members (professors, researchers, graduate and undergraduate students) from various fields like engineering, medicine, mathematics, physics,chemistry and biology are involved. The mainorganizer is prof. Radu Dobrescu from PolitehnicaUniversity. The group already organized the First South-East European Symposium on "Interdisciplinary Approaches in Fractal Analysis-IAFA 2003. This Symposium was a succes due to the large cooperation between romanian researchers and researchers from manyother countries. There were about 50 papers presented from which at least 20 from the guests.

In the present, the seminar is dedicated to chaos theory with application in medical imaging, especially the analysis of tumours. The problem is to find good methods for understanding the morphology of tumours, tissue homogeneity and growing phenomena. Some PH.D. thesis, elaborated on these subjects by some members of the seminar, are in progress.

ROMSIM was involved in organization of the EUROSIM Congress 200. Four members of ROMSIM wasmembers of the International Program Committee of the Congress.

At the same time ROMSIM encouraged its members to prepare and submit papers at this Congress. As a result a representative participation of ROMSIM to Eurosim Congress 2007 was registered.

Two members of ROMSIM attended the MATHMOD Conference held in Vienna in February 2006. ROMSIM was represented at the Eurosim Board Meeting, held in Vienna, February 11, 2006.

ROMSIM is involved in organization of the periodic scientific seminary on Systems modeling and Simulation; the seminary is attended each time by 15 to 20 specialists.

During the seminary participants present and discuss both theoretical and applied contributions in the field of systems modeling and simulation.

Some of ROMSIM members attended the Workshop Principles of Modeling of Complex Ecological Systems, organized by the Faculty of Biology from University of Bucharest.

Present and Coming Events

We emphasize also the activity of ROMSIM members in the field of publishing books, monographs and articles in international and/or Romanian journals. Some monographs are to be published in a new Series titled Technologies of Information, of Technical Publishing House, Bucharest. Some research articles will be published in the Romanian journals SIC-Studies in Information and Control and RRIA-Romanian Journal of Informatics and Automatics. ROMSIM members ensure the reviewing of articles submitted by authors to Editorial Staff of these journals.

A review of this book has been published in SNE Volume 16 Number 1 (SNE 46). Both books have the same author: dr. Florin Stanciulescu.

Another editorial event involving ROMSIM is the publication by the Romanian Academy Publishing House of the book titled "Mathematical Models for Optimal Asset Allocation"; authors are Marius Radulescu, Sorin Radulescu and Constantza Zoie Radulescu.

At the same time some members of ROMSIM (as dr. Florin Hartescu, dr. Constantza Zoie Radulescu and others) have published research articles in Romanian Journal for Informatics and Automatics.

One book with a subject connected to ruin theory (which has some simulation models), author Gheorghita Zbaganu was published this year in a collection of the Publishing House Geometry Balkan Press.

Some of the ROMSIM members had participated to international conferences (EURO 2006 conference in Reikjavik, Operations Research 2006 international conference in Karlsruhe, the EFITA 2007 conference in Glasgow, EURO 2007 conference in Prague etc) with papers in the domain of mathematical modeling and simulation.

Some Phd theses, elaborated on simulation and modeling subjects by some members of the seminar, are in progress. We emphasize that two members of ROMSIM, dr. Constantza Zoie Radulescu - Secretary of ROMSIM and dr. Marius Radulescu, will represent our Society to the Eurosim Board Meeting from September 11, 2007.
