The design of large systems often involves the creation of models that describe partial specifications. Model composition is the process of combining partial models to create a single coherent model. This paper presents an automatic composition technique for creating a sequence diagram from partial specifications captured in multiple sequence diagrams with the help of Alloy. Our contribution is twofold: a novel true-concurrent semantics for sequence diagram composition, and a model-driven transformation of sequence diagrams to Alloy that preserves the semantics of composition defined. We have created a tool SD2Alloy that implements the technique as follows: two given sequence diagrams are transformed into two Alloy models, and merged according to a set of syntactic logical constraints describing how their elements should be matched. These constraints are in accordance to our compositional semantics. The technique can also be used to detect problems and inconsistencies in the composition of diagrams. |

Weaving True-Concurrent Aspects using Constraint Solvers |
|
ملخص المشاركة: |
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 crosscutting 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. |
