Abstract:
The famous philosopher Heraclitus said that “the only thing that does not change, is change itself.” This statement is certainly valid for today's businesses. Globalization and advancement in computer technology help businesses to reach further markets; however, this increases the competition for the same customer base and forces businesses to innovate more frequently than ever before. In the face of constant change, businesses must make sure that their response to change is quick enough to stay competitive.
 
Adapting to change in a timely manner requires businesses to have dynamic and flexible processes. A business process implemented as a composition of services is easier to modify because each service can easily be swapped with another that has a more pertinent implementation. The goal of automated service composition is to compute new business processes to satisfy new business requirements by leveraging available services.
 
In this talk, we present our efforts to model and analyze the automated service composition problem. We follow an automata-theoretic approach and our analysis considers various cases including services with finite states, services with bounded states, and services with qualities. Our results show that the complexity of the problem increases as the expressive power of the service models increase.
