Because things have changed!

Development of software for the assistance of engineering activities started with functionalities to replace manual documentation work and to allow for engineering activities which can not be achieved by conventional methods during the seventies and eighties. During nineties, associative parametric object model was a great advancement in modeling mainly in development, analysis, and manufacturing planning of parts and assemblies. Two main achievements at the start of this century were contextual integration of engineering model and reusing proven practice and experience controlled active knowledge. Recent developments targeted modeling of engineering structure (product or experimental configuration) as system, integration of research in modeling of these structures, development of multidisciplinary structure using a single model, and organizing knowledge in intellectual property (IP) of an organization. New and not everywhere recognized new achievement is the inherent integration of theory and practice in engineering modeling environment. Separation of theory and practice seems to be over soon.

The Laboratory of Intelligent Engineering System and its predecessor laboratories (see below) were developed along the above road and always represented the highest level engineering technology. Teaching programs, research results, and high number of internationally recognized publications are evidences of a continuous development.

This is a knowledge driven active laboratory where students and teachers communicate with active modeling procedures in order to better understand competences, projects, and case studies during lectures and laboratories.

Future of the laboratory is anticipated as a 21st century virtual space in which arbitrary virtual spaces can be opened as service from cloud for the purpose of university courses, research and development consortium and other projects, public relation and education activities, etc. This improvement will depend on future accepted development program and availability of resources.

We are waiting for BSc, MSc, and PhD students who would like learn about the most advanced engineering methods using most advanced engineering information technology. Courses and topics are announced in programs of the Óbuda University.


Purpose of the laboratory is introduction, teaching, research and application of theories, methodologies and systems which represent and integrate leading theory and practice of engineering in consistent systems of twenty-first century model centric engineering informatics.

Research and education laboratory provides integrated multidisciplinary environment for virtual engineering. It represents leading industry level information system for lifecycle activities of engineers. Emphases are on requirements, functional, logical and physical (RFLP) structure based product modeling, and representation of active engineering knowledge using applied mathematics and intelligent computing. Laboratory background is provided for the Institute of Applied Mathematics, John von Neumann Faculty of Informatics and the Doctoral School of Applied Mathematics and Applied Informatics at the Óbuda University in the areas of applied mathematics and intelligent informatics. More information. 

Laboratory offers courses in PLM related informatics, mathematics, engineering modeling, and systems engineering for students who enrolled in information technology, multidisciplinary engineering, and PhD research programs. Courses are available on BSc, MSc és PhD levels.


Essential outcome of course programs is seeing and thinking in engineering specific virtual information space. Basic outcome is to understand self adaptive generic object modeling which is based on built in active knowledge and high level abstraction. In order to achieve new learning outcomes lectures can be arranged in laboratory with personally available model space at student workstations in case of courses where small group (max. 14)is feasible.

Modeling system and associated virtual technology supports university level education and research in lifecycle management of product information (PLM). Currently, laboratory is based on the Dassault Systémes V6 and V5 PLM installation. Our license is for education and nonprofit research without providing models for outside organization. In case of company ordered and financed modeling, we must ask for research license. Our current V6 PLM  includes the discover level. Master and advance level extension is planned mainly for the RFLP structure based product definition. Multilevel Abstraction Based Self Control Method for Industrial PLM Model.
