In this paper, the concept of Abramov's method for transferring boundary conditions posed for regular ordinary diierential equations is applied to index 1 DAEs. Having discussed the reduction of inhomogeneous problems to homogeneous ones and analyzed the underlying ideas of Abramov's method, we consider boundary value problems for index 1 linear DAEs both(More)
In this paper we describe the first steps of a PhD programme, having the goal to develop a common meta-model for different software quality approaches and methods. We focus on presenting the structure of quality approaches emphasizing the similarities amongst them. Understanding the structure of quality approaches helps supporting organizations in using(More)
Many of quality approaches are described in hundreds of textual pages (see CMMI, SPICE, Enterprise SPICE, ITIL among others). Manual processing of information consumes plenty of resources. In this report we present a text mining approach applied on CMMI – one well known and widely known quality approach. The text mining analysis can provide a quick overview(More)
The article supports the idea that nowadays using more software quality models in a synergic way and customizing them to fit the specific needs of an organization is the only viable option for doing efficient process improvement in software companies. The argumentation is done by presenting a theoretical framework in which the quality models can be placed.(More)
1. Research area and sub-area Multi-model software process improvement. This research defines a method for process based unification of multiple process-oriented software quality approaches. 3. Description of the research problem and its importance in the field Several quality methods, standards and models are available to guide software developing(More)

This report summarizes the selection process performed in order to ensure a modelling language of sufficient quality for describing processes based on multiple software quality models and standards. UML activity diagrams, EPCs and BPMNs are compared based on well-defined criteria: intelligibility, ability of expressing process elements and workflow(More)
The article focuses on a problem software companies often face: the need to choose a software quality model that, besides being auditable, ensures the connection of quality goals to the business goals of that company. A good solution seems to be to quit relying exclusively on one quality model and use more models in a synergic way instead. We explain a(More)
