A tutorial on ABCmod: An Activity Based discrete event Conceptual modelling framework
Bibliographic record
Abstract
The notion of a conceptual model is present in any discussion about the modelling and simulation process within the discrete event dynamic system domain (Robinson 2011). This paper presents an overview on an activity-based conceptual modelling framework: Activity Based Conceptual modelling = ABCmod (Birta and Arbez 2013). It transforms the general notion of a conceptual model to into a specific conceptual modelling artefact. The ABCmod framework encompasses the naturalness of the activity perspective which has considerable intuitive appeal (Pidd 2004a and 2004b). ABCmod accommodates both the structural and the behavioral aspects that are fundamental components of any conceptual model and provides a collection of constructs both for handling input/output and for dealing with special circumstances such as pre-emption, interruption and balking. We provide an overview of the framework and illustrate many of its features in examples.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
