-<summary>Abstract</summary>
-<blockquote>
-<p>Declarative behavioural modelling is a powerful modelling paradigm
-that enables users to model system functionality abstractly and
-formally. An abstract model is a concise and compact representation
-of key characteristics of a system, and enables the stakeholders to
-reason about the correctness of the system in the early stages of
-development.</p>
-
-<p>There are many different declarative languages and they have
-greatly varying constructs for representing a transition system, and
-they sometimes differ in rather subtle ways. In this thesis, we
-compare seven formal declarative modelling languages B, Event-B,
-Alloy, Dash, TLA<sup>+</sup>, PlusCal, and AsmetaL on several
-criteria. We classify these criteria under three main categories:
-structuring transition systems (control modelling), data descriptions
-in transition systems (data modelling), and modularity aspects of
-modelling. We developed this comparison by completing a set of case
-studies across the data- vs. control-oriented spectrum in all of the
-above languages.</p>
-
-<p>Structurally, a transition system is comprised of a snapshot
-declaration and snapshot space, initialization, and a transition
-relation, which is potentially composed of individual transitions.
-We meticulously outline the differences between the languages with
-respect to how the modeller would express each of the above components
-of a transition system in each language, and include discussions
-regarding stuttering and inconsistencies in the transition relation.
-Data-related aspects of a formal model include use of basic and
-composite datatypes, well-formedness and typechecking, and separation
-of name spaces with respect to global and local variables. Modularity
-criteria includes subtransition systems and data decomposition.
-We employ a series of small and concise exemplars we have devised to
-highlight these differences in each language. To help modellers
-answer the important question of which declarative modelling language
-may be most suited for modelling their system, we present
-recommendations based on our observations about the differentiating
-characteristics of each of these languages.</p>
