Presented work covers one of the most important areas of OMG’s model driven architecture (MDA) – problems of object model transformations. Based on research of OMG specifications and other sources, author analyzes transformation process, states importance of modeling and metamodeling for designing of UML like modeling languages. Research work describes designed PIM ant PSM metamodels of aggregate systems. Structure and syntax of ATL and MTL model transformation languages was introduced. Author gives a short overview of model editors and graphical representation for these languages, created using EMF framework tools. Transformation languages have been compared. A result of experimental transformations was summarized by their qualitative and quantitative criteria. Advantages of hybrid ATL transformation language versus imperative MTL language were found. Experimental transformations were successfully produced and executed using ATL and MTL model transformation languages.

Mūsų dienomis informacinės sistemos tampa vis sudėtingesnės ir verslo procesams aprašyti seniai nebeužtenka paprastų tekstų ar schemų. Kompiuterizuotų IS reikalavimams aprašyti ir modeliuoti geriausiai tinka specialiai tam skirti modeliai. Modeliavimas tapo būtinas kuriant dideles, sudėtingas ar su kitomis sistemomis sąveikaujančias informacines sistemas, nors daugelis programuotojų siekia minimizuoti modeliavimo pastangas. Modeliuojami ne tik vartotojo poreikiai, dalykinė sritis, programinė įranga, bet ir organizacijos veikla - pastaraisiais metais ši modeliavimo fazė tapo daugelio projektavimo procesų dalimi. Todėl specialūs kompiuterizuoti modeliavimo įrankiai tapo neatskiriama sudėtingų IS kūrimo ir projektavimo dalimi. Modernėjant technologijoms vis labiau orientuojamasi į reikalavimų specifikavimo fazę IS kūrimo projektuose – reikalavimai turi lemiamą reikšmę projektuojant modernias ir sudėtingas informacines sistemas. Todėl vis didėja projektavimo įrankių įtaka IS kūrimo procese, jų pagalba kartais generuojant ir kodą. Taigi, kad tinkamai būtų sukurta ir vystoma nauja sistema, būtina tinkamai apsibrėžti viziją, veiklos modelį ir tiksliai specifikuoti reikalavimus. Šis procesas, bei veiklos modelio transformavimas į vartotojo reikalavimų sistemai modelį aptariamas šiame darbe. / In nowadays information systems are becoming more and more sophisticated and for business process definition it is not enough to use simple schemas and text. For information systems requirements there are created special models. Systems modeling became a must for creating big, sophisticated, difficult systems. User’s requirements, subject matter and specialty domain, software architecture and even organizations activities are being modeled in modern software development companies during systems design process. Special modeling tools are used to create information systems. During last few years software and business developers are focusing more to requirements specification phase. In information systems development projects strict and simply understandable requirements have critical meaning creating big sophisticated information systems. So usage of design and modeling tools is more and more popular. Using such tools sometimes program code is generated to. To develop stable system is crucial to have a vision, make good activity model and specify requirements for future system. This work covers the method of the formation of transformation between activity and use-case models. This transformation is based developing business vision and requirements to future system. The algorithm of transformation described is this work, formally defines the described models elements relations between each other. Solution, based on described algorithm was made on MagicDraw UML tool platform... [to full text]

Disertacijoje tiriamas sprendimų modelių kūrimas verslo taisyklių ir procesų modelių pagalba bei šių modelių transformacijos į programų sistemų komponentus realizuojančius automatizuotus sprendimus informacinėje sistemoje. Analitinėje disertacijos dalyje apžvelgiami sprendimu modeliai ir metodai skirti intelektualizuotų informacinių sistemų kūrimui. Tolimesniuose skyriuose pateikiamas, remiantis analizės rezultatais, sukurtas modelių karkasas ir jo pagrindu sukurtas metodas skirtas sprendimų modelių automatizavimui. Baigiamajame disertacijos skyriuje aprašomi eksperimentai, kuriuose atliekamos sprendimų modelių transformacijos. Galiausiai pateikiami eksperimentų rezultatai ir galutinės išvados. / In the presented thesis we offer modernisation of information system development methods used for implementation of automated information-, rule-, knowledge- and model-based decision processes assisted by early separation and development of a business logic model and implementation of decision-making and knowledge discovery process models with further support to business people with suitable interfaces for modification of decision-making processes without involvement of software developers in later exploitation stages. In the analytical part of the dissertation, decision models and methods of intellectualised information systems are analysed. According to the results obtained during the analysis, investigation on the proposed framework and a decision model based method for decision-making process automation is carried out. In the final chapter several experiments are described in order to evaluate the proposed method, and the general conclusions complete the research.
