Business Processes in a Distributed Surveillance System Integrated Through Workflow

Abstract

SIMPOZ project aims at building a highly configurable system for surveillance of public areas and objects of a special importance based on the analysis of digital images. Distributed nature and potential diversity of monitoring features, a large number of alarm signals fed by various sensors, the need to ensure a flexible event flow management and tailored to needs emergency response processes were motivations to utilize workflow as a management and integration layer. Implementation of workflow processes was preceded by business modeling with ArchiMate language. The presented models of business processes reflect the specificity and characteristics of surveillance systems: reactive character, event driven control and a large number of asynchronous data flows. Lessons learned indicate, that ArchiMate models in spite of the smaller set of dedicated behavioral constructs with respect to for example BPMN, after adopting certain modeling conventions, allow to reach high level of expressiveness.
