Rules from cognition for conceptual modelling

Conceptual Modelling is a cognitive intensive process. Prior research has acknowledged the importance of cognitive theories and their implications for Conceptual Modelling. Several authors have developed hypotheses to give modellers a hint how to improve their models. Although much effort has been made, researchers and practitioners cannot easily apply or broaden these hypotheses. Yet, they are forced to spend a lot of review work, as a comprehensive overview about past research is missing. With this paper we give a review of hypotheses developed from Cognition for Conceptual Modelling.

Perceptually Discriminating Chunks in Business Process Models

Perceptual Discriminability can be used to help distinguishing modeling constructs in conceptual models as well as to produce parallel processing which makes these constructs pop-out from the rest of the model. Prior research has already shown advantages of a pop-out for single constructs and for matching operators. This paper focusses on constructs that are perceived as a single chunk of information. Based on experiences from chunking and template theory relevant BPM-chunks are derived and moved towards parallel processing. We further report on the results of an experiment that tests the impact on comprehension speed for novices for this approach.

The Potential of Reference Modeling for Simulating Mobile Construction Machinery

This research-in-progress paper summarizes first results of the INPROVY project by applying reference modeling to the simulation of mobile construction machinery. Four Business cases for a potential application of reference modeling are derived by an expert interview. For these four business cases this paper discusses principles of reference modeling can be applied best and how reference modeling can be used to support Simulation of Mobile Construction Machinery economically.

Perceptual Discriminability in Conceptual Modeling

Perceptual discriminability can be used to help distinguishing modeling constructs in conceptual models. It can further be used to produce parallel processing of modeling constructs that make these constructs virtually pop-out from the model. Moody has described a condition which is necessary to produce a pop-out effect in his principle of perceptual discriminability. This work extends the principle of perceptual discriminability for further conditions to produce a pop-out. Extended perceptual discriminability is exemplarily applied to a modeling grammar.
