2. Engineering of industrial production systems using AML

AutomationML (AML) is a standard for
tool data exchange= domain = tool = doc

use in industrial automation systems engineering -

Electrotechnical Commission, 2014.

3. Challenges in parallel multi-disciplinary Engineering
2
1. Tool networks do not
ensure sufficient data
consistency.
2. Data cannot be queried
using an uniform
interface.
3. Tool networks do not
make data easily and
efficiently accessible on
project level, e.g., for risk
management, test
automation or observation
of project progress.

1. Version management on various semantic model element levels
2. Building an integrated AML plant function tree
3. Mapping between file content and integrated AML plant function tree

9. Evaluation with a Lab-Sized Plant at Uni Magdeburg

Lab-sized Production System

• RQ1 Roundtrip capabilites
• Are transformations between
AML XML and AML models possible
without loss of information?
• Result: All reference examples and
real world examples could be
transformed to AML models and back
to AML XML without loss of information
• RQ2 Integration capabilites
• Is the linking language expressive
enough for practical settings?
• Result: All mappings of a lab-sized
production system (picture to the right)
could be modeled

10. Capabilities of the Model-Driven Approach
9
1. Re-use of established Model-Driven Techniques
(e.g. Code-Generation, Model-Validation, Model-Transformations,…)
2. Queries on models with the Object Constraint Language (OCL)
a. Show all elements of a specific type (e.g. sensors)
b. What is the energy consumption of the plant?
c. Show all parts that have reached their maximum working hours
3. Reasoning for consistency checking
a. Are there any broken links within the project?
b. Is there a newer component available?

11. Conclusion and Outlook
• The AML Hub allows data integration of multi-disciplinary engineering
artefacts
• Model Driven Approach was effective and efficient to provide a software
tool prototype with Linking and Versioning capabilities
• The feasibility of the approach was shown in a real world case study
• Outlook: Risk management based on advanced reasoning
• We will be happy to demonstrate the tool prototype an answer your
questions after the talk
