 Business Process Model & Notation  Formalized Process Description a general integrated approach to process specification and design / run time verification. Process ssSpecif cifica ication ionTechniqu niques But what we we found und missi sing ngis is …  Design time

  • E.g. Simulink Design Verifier
  • Temporal logics / patterns
  • Life sequence charts
  • UML communication diagrams

 Run time

  • Run time verification / monitoring

Conclusion » Benefits and Future Work

2014/09/30 Georg Hackenberg - Formal Technical Process Specification and Verification 25

 Obervation interface allows to…

  • Decouple and integrate process and

system specification

  • Model process specification over

abstract observation streams

  • Model system specification using
  • bserver components

 Verification technique allows to…

  • Prove process satisfaction both at

design and at run time

 Improve graphical notation of the process specification

  • Reduce modeling effort through

inclusion of specification patterns

 Analyze and improve scalability of the presented approach

  • Prove process satisfaction for the

entire pick and place unit

  • Prove process satisfaction step-wise

from activity to activity?

Benefit its Futur ure Work
