Biography
Artem Polyvyanyy was born in Mariupol, Ukraine in 1983. He is a research assistant and a PhD candidate at Business Process Technology research group at Hasso Plattner Institute of IT Systems Engineering at the University of Potsdam, Germany. He is a member of the Research School on Service-Oriented Systems Engineering at Hasso Plattner Institute. His research areas are business process management and service-oriented computing. In particular, his topics of interest are process abstraction and verification, modeling of ad-hoc processes, and service science. Artem has published his research results at international conferences on business process management. He has a strong background in computer science, software engineering, and business process management from the National University of Kyiv-Mohyla Academy in Ukraine and Hasso Plattner Institute in Germany. His industry experience includes internships at Wincor-Nixdorf GmbH in Hamburg, Germany and SAP Labs in Palo Alto, USA.
Research Topic
Software engineering went a long way from low level programming languages to process models (both defining control flow, but on different abstraction levels). The driving force for such an evolution was (and still remains) reuse. On one hand, engineers want to operate with coarse grained statements when describing algorithms, on the other, stay flexible when capturing an arbitrary system. Achievement of the equilibrium point is impossible, approaching it is research. At the end, it is about the choice of abstraction level to operate at.
My research concentrates on the questions regarding structural aggregation of control flow logic, i.e., searching for meaningful process fragments suitable for generalization. Assuming the existence of executable processes, the questions to be answered are: how to extract coarse grained fragments of process logic, can the system be expressed in less lines of code or modeling constructs, what are the methodologies and implications. In order to answer these questions I reuse and improve the existing, but also develop new techniques of process model decomposition.
Finally, in order to achieve flexibility in describing special kind of processes that capture ad-hoc scenarios (instance rich processes), I develop and shape the technique of Flexible Process Graphs (FPG). Instead of structural generalization, FPG proposes generalization of the control flow logic. The core process modeling construct - a sequential execution constraint between two activities, is replaced in FPG by the relation on two sets of activities. Once all the prerequisite activities are accomplished, another set can be enabled for execution.
