PhD Thesis:

A copy of the thesis can be found here.

Software has become a key component of a rapidly growing range of applications, products and services from all sectors of economic activity. This can be observed in large-scale heterogeneous systems, embedded systems for automotive applications, telecommunications, wireless ad hoc systems, business applications with an emphasis on web services etc. Such systems are commonly called software-intensive systems. Software-intensive systems are characterized by their reactive nature, real-time requirements, mix of continuous and discrete (hybrid) behaviour, the embedded character of some components of the system, the required dependability and the distribution of its elements.

Multi-Paradigm Modelling has already been proposed as a method for the development and verification of software-intensive systems. In multi-paradigm modelling every aspect of a system is modelled explicitly, at the most appropriate level(s) of abstraction, using the most appropriate formalism(s). This thesis attempts to close some of the remaining gaps for the design, verification and deployment of software-intensive systems.

Since multi-paradigm modelling promotes the explicit modelling of all aspects of a system, the process to design, verify and deploy systems has to be explicitly modelled as well. We propose the Formalism Transformation Graph and Process Model (FTG+PM) for this purpose. The FTG+PM contains, on the one hand, the definition of all formalisms and transformations involved in creating software-intensive systems. On the other hand, these formalisms and transformations are used within a process to create the systems.

The FTG+PM is applied to the creation of an automotive exemplar, the power window system. Several languages and transformations are identified to create the exemplar. The process starts with the modelling of requirements. Domain-specific languages are used to model different aspects of the system (namely: the environment, plant and control model). These models are transformed to Petri nets for verification and to a hybrid simulation model to evaluate the dynamic behaviour of the system. Finally, the system is deployed to a network of electronic control units.

During deployment it is necessary to evaluate the behaviour and other extra-functional properties of the solution. It is however not feasible to build the system and check the behaviour at the implementation level. Therefore, the Discrete Event System Specification is evaluated as an appropriate formalism for the simulation of deployed software-intensive systems.

System-level performance models however require calibration of the involved parameters to reflect the actual system behaviour. Since all aspects of the system are modelled, these models can be used to generate a calibration infrastructure. From the execution of the calibration infrastructure, a performance model can be built for calibration, i.e., to estimate the parameters of the simulation models of deployed software-intensive systems.

Finally, we evaluate the feasibility of transformations to optimise the deployment of software-intensive systems. A number of methods are used to leverage the explosion of the design-space. Firstly, multiple levels of abstraction/approximation are used where non-feasible solutions (or solutions that will never be optimal) are pruned. Secondly, general search techniques are introduced in transformation models to search the design space. Finally, if an existing optimisation model exists, the deployment model is transformed to this model. The FTG+PM is used for this purpose.
