Abstract:Business process management (BPM) has emerged as a dominant
technology in current enterprise systems and business
solutions. However, the technology continues to face challenges in
coping with dynamic business environments where requirements and
goals are constantly changing. In this presentation, we present a
modelling framework for business processes that is conducive to
dynamic change and the need for flexibility in execution. This
framework is based on the notion of process constraints. Process
constraints may be specified for any aspect of a process, such as
task selection, control flow, resource allocation, etc. Our focus in
this talk is on a set of scheduling constraints specified through a
temporal constraint network. We will demonstrate how this
specification can lead to increased flexibility in process
execution, while maintaining a desired level of control. A key
feature and strength of the approach is to use the power of
constraints, while still preserving the intuition and visual appeal
of graphical languages for process modelling. Initial work on
scheduling constraints has led to exciting new options for extending
the approach to other constraint types and ultimately providing a
uniform constraint specification framework. Furthermore, this
approach can also be utilized to provide extended support for
dynamic instance building. These issues form part of the future work
of this research.
