The process control domain is intrinsically complex and dynamic. It has proved to be difficult to construct and maintain process control systems under the traditional software development methodologies. Object Orientation is the latest paradigm in software development. The reason for its widespread acceptance is that it allows the application of the principles of hierarchical structuring and component abstraction which is essential in building large systems. It also promotes component reusability which makes systems easier to maintain and modify. For the process control domain, these are important benefits. Furthermore, most process control systems have physical devices which can be modeled naturally as objects with the timing and performance issues of each object directly addressed. A Target System Reference Model which addresses various aspects of the process control domain is proposed within this dissertation. The objective is to provide a frame of reference within which a process control system can function. / Computing / M. Sc. (Computer Science)

It is widely recognised that information and communication technologies development is a risky activity. Despite the advances in software engineering, many software development projects fail to satisfy the clients' needs, to deliver on time or to stay within budget. Among the various factors that are considered to cause failure, an inadequate requirements practice stands out. Model-driven development is a relatively recent paradigm with the potential to solve some of the dragging problems of software development. Models play a paramount role in model-driven development: several modelling layers allow defining views of the system under construction at different abstraction levels, and model transformations facilitate the transition from one layer to the other. However, how to effectively integrate requirements engineering within model-driven development is still an open research challenge. This thesis integrates Communication Analysis, a communication-oriented business process modelling and requirements engineering method for information systems development, and the OO Method, an object-oriented model-driven software development method provides automatic software generation from conceptual models. We first provide a detailed specification of Communication Analysis intended to facilitate the integration; among other improvements to the method, we build an ontology-based set of concept definitions in which to ground the method, we provide precise methodological guidelines, we create a metamodel for the modelling languages included in the method, and we provide tools to support the creation of Communication Analysis requirements models. Then we perform the integration by providing a technique to systematically derive OO-Method conceptual models from Communication Analysis requirements models. The derivation technique is offered in two flavours: a set of rules to be manually applied by a human analyst, and an ATL model transformation that automates this task. / España Cubillo, S. (2011).

The research is conducted in the area of Software Engineering, with emphasis on the design phase of the Software Development Life Cycle (SDLC). The object-oriented paradigm is the point of departure. The investigation deals with the problem of creating support for the design phase of object-oriented system development. This support must be able to guide the system designer through the design process, according to a sound design method, highlight opportunities for prototyping and point out where to re-iterate a design step, for example. A solution is proposed in the form of a knowledge-based support system. In the prototype this support guides a designer partially through the first step of the System Design task for object-oriented design. The intention is that the knowledge-based system should capture the know-how of an expert system designer and assist an inexperienced system designer to create good designs. / Computing / M. Sc.
