Abstract: In Service-oriented Architectures, business processes can be realized by composing loosely coupled services. If services in the Internet of Services with comparable functionalities but varying quality levels are available at different costs on service marketplaces, service requesters can decide, which services from which service providers to select. The work at hand addresses computing an optimal solution to this serviceselection- problem considering complex workflow patterns. For this, a linear optimization problem is formulated, which can be solved by applying integer linear programming techniques.
