2nd International Workshop on the Adequacy of Modeling
Methods (AQEMO'2018)
The focus on adequacy in the design of modeling methods implies that various aspects
need to be taken into account to ensure that the method corresponds to the requirements
of the given application domain and its different target user groups. This has effects on
the modeling language including its syntax, semantics, notation, the modeling proce-
dures and algorithms, as well as on the choice of the actual implementation environment.
In this context, it also needs to be described how adequacy can be described and poten-
tially evaluated. This leads to a range of implications such as the evaluation of modeling
methods and resulting models in terms of adequacy as well as the learning and teaching
of adequacy through experience or structured learning procedures.
The Workshop on the Adequacy of Modeling Methods aims at establishing a platform
for interested researchers and practitioners to exchange ideas and reveal co-operation
opportunities. The second edition of the AQEMO workshop was held in Braunschweig
as a satellite event of the Modellierung’2018 conference. As only one paper has been
submitted and accepted for the workshop, it was decided to join it with two papers sub-
mitted to the International Workshop on Petri Nets and Modeling (PeMod) as well as to
include two keynotes as invited talks and a panel discussion.
At the beginning of the workshop, Bernhard Thalheim gave a keynote on the founda-
tions and future research challenges of model adequacy based on the the Kiel compendi-
um of models, modeling activities and systematic modeling. For this purpose, he referred
to two modeling methods from the domain of data modeling. Subsequently, Mathias
Uslar and Sebastian Hanna presented a three-dimensional visualization approach for the
RAMI 4.0 reference model for Industry 4.0 architectures that aims to reduce the model-
ing effort for the requirements engineering of complex technical solutions. In the follow-
ing, two papers from the PeMod’2018 workshop were presented that showed a new
visualization approach for the synthesis of Petri nets and an approach for a combination
of reconfigurable and hierarchical Petri nets. In the second keynote of the workshop,
Stefan Strecker discussed the concepts of model evaluation and model quality with refer-
ences to aspects of linguistics, philosophy of language, cross-disciplinary fields and
fundamental considerations in other branches of philosophy. The workshop was con-
cluded with a panel discussion led by Heinrich C. Mayr involving all speakers as well as
the organizers of the AQEMO and the PeMod workshop on the challenges and future
research questions in the context of model adequacy.
AQEMO would not have become reality without the support of a number of people.
First, we are very grateful to the authors and keynote speakers for their intensive work.
Second, we would like to thank the program committee members for providing timely
and thorough assessments. Furthermore, our thanks go to the Modellierung 2018 organ-
izers for hosting this workshop.
