Large system models usually consist of several simpler models that can be understood more easily. Making changes to the behaviour of a component will likely affect several models and could introduce accidental errors. Aspects
address this by modelling new functionality required in several places as an
advice, which can be integrated with the original base models by specifying a
pointcut. Before checking that the overall outcome is correct, we need to weave the cross-cutting advice into the base models, and obtain new augmented
models. Although considerable research has been done to weave models, many such approaches are not fully automated. This paper looks at aspect weaving of scenario-based models, where aspects are given a true-concurrent semantics based on event structures. Our contribution is a novel formal automated
technique for weaving aspects using the Z3-SMT solver. We compare the performance of Alloy and Z3 to justify our choice.
