Abstract
Web service-based workflow management systems have
garnered considerable attention for automating and
scheduling dependent operations. Such systems often sup-
port user preferences, e.g., time of completion, but with the
rebirth of distributed computing via the grid/cloud, new
challenges are abound: multiple disparate data sources,
networks, nodes, and the potential for moving very large
datasets. In this paper, we present a framework for integrat-
ing QoS support in a service workflow composition system.
The relationship between workflow execution time and ac-
curacy is exploited through an automatic workflow compo-
sition scheme. The algorithm, equipped with a framework
