Optimizing Business Processes using Attributed Petri Nets

B. Eichenauer, 9. Proceedings of the 9. Symposium about Simulation as Commercial Decision Help, March 15 to 17, 2004, Braunlage (Germany), pp. 323-338, ISBN 3-930185-27-X

A method is described which allows the exact modeling and optimization of business processes under arbitrary constraints.

In recent years the optimization of business processes has gained increasing attention since it can be used to reduce costs with relatively low effort. Furthermore, it is the endmost opportunity at hand to counter the cost pressure that arises from the globalization of markets. In this paper we introduce a method to create exact and executable models of discrete processes. The models can be optimized using mathematical methods. The introduced method has been proven in numerous applications.

Simulation a Modern Aid for Planning, Developing, Controlling

With the simulator development system PACE commercial and technical systems are modeled exactly in all details and completely up to an arbitrarily defined depth. The developed virtual systems (models) can be executed on a computer and deliver results with respect to the dynamic behavior and the co-operation of system parts and about the effectiveness of the planned actions ...

The Nature & Pitfalls of Conventional Planning & Simulation

To save time and money is a constant challenge for enterprises and requires continuous strategic planning. In most cases, the same resulting questions arise and often seem to be unanswerable:

• How and where can costs be reduced or saved?
• How should a business process be structured in detail to ensure a particular operational goal?
• How can a specific process (e.g., movement of goods, processing returns) be optimized?
• Is a process as actually implemented really optimally organized?
• What resources are really necessary for a certain process?
• How should a process be restructured when goals and resources change?

A Procedure for a Unified Approach to Analysis and Development Projects

B. Eichenauer

This article was written to show that previous objections to the Petri net method no longer apply, and to demonstrate the enormous advantages this method provides in working on analysis and development projects.

Transformation of CIMOSA-Models into Petrinet-Models with PACE

Bernd Eichenauer und Martin Zelm

Enterprise modeling provides the means to capture, structure and manage the enterprise system and to identify the needed and produced information. CIMOSA (CIM Open System Architecture) provides a process-oriented modeling concept to capture both process functionality and process behavior. Petri net models are very powerful to model process scenarios with the objective to achieve computer-executable models, which enable quantitative, exact results of the simulated processes.

CIMOSA models created with user-oriented constructs can serve various purposes in simulation and operation control, providing primarily qualitative results. Petri net models, yield mathematically exact quantitative simulation results. The models are generally less transparent due to the more formal representation needed in mathematical simulation.

This paper describes general rules to transform CIMOSA models into Petri net models, created with the modeling tool PACE. The method is deduced on a basis of modeling constructs and illustrated with an example of a simple process modeling scenario. More work is required to extend and validate more complex transformation rules.
