188 ISTVAN GERGELY CZIBULA systems into object-oriented ones. We have also illustrated how our approach is applied for transforming a simple program written in Pascal into an equivalent objectoriented system. Advantages of our approach in comparison with existing similar approaches are also emphasized. Further work will be done in the following directions: • To improve the distance function used in the clustering process. • To extend our approach in order to also determine relationships (class hierarchies) between the application classes obtained in the object-oriented system. • To apply kOOS algorithm on large software systems.

PÂRV, I. LAZĂR, S. MOTOGNA, I-G. CZIBULA, C-L. LAZĂR(1) Abstract. This work is part of a series referring ComDeValCo - a framework for Software Component Definition, Validation, and Composition. Its constituents are: a modeling language, a component repository and a set of tools. The current paper describes the status of the project after implementing procedural and modular concepts. 1. Introduction UML 2.0 introduced the action semantics, aimed to help the construction of executable models [3]. The behavior of such models is completely defined down to statement level, making possible their construction and execution by tools able to interpret UML 2.0 semantics. Unfortunately, this important breakthrough did not increased the use of UML models in the software development process. The main reasons are at least the following: (1) UML is too general (being unified) and its semantics contains extension points deferred to the concrete use of the language; (2) the construction of detailed models (down to statement level) with existing tools is too dificult, these tools being too general and (3) there is a lack of (agile) mature development processes based on executable models. The above premises were the starting point of the ComDeValCo project: a framework for component definition, validation, and composition. Its constituents are: a modeling language, a component repository, and a set of tools. The software component model is described by an platform-independent modeling language. Component repository represents the persistent part of the framework, containing the models of all full validated components. The toolset is intended to automate many tasks and to assist developers in performing component definition (DEFCOMP) and V & V (VALCOMP, SIMCOMP), maintenance of component repository (REPCOMP), and component assembly (DEFSYS, VALSYS, SYMSYS, GENEXE). 2000 Mathematics Subject Classification. 68N30.
