During the system and software development process for distributed systems, the development of the overall system design is critical for correctness, performance, and reliability. The objective of this thesis is the improvement of methods and tools that can be used to obtain a correct design model for distributed system components automatically by deriving the design model from the global system requirements. Mainly, we are concerned with the transformation from a global requirements model to a distributed design model. The global requirements model describes the behavior of a distributed system in an abstract manner by defining the local actions to be performed by different roles which represent actors in the different system components. The distributed design model defines the behavior of each actor separately, including its local actions plus the exchange of coordination messages, which are necessary to assure that the actions are performed in the required order. In this work, we first consider a global requirements model in the form of partially ordered actions similar to High-level Message Sequence Chart (HMSC). We study the realizability of the global requirements, which is said to be directly realizable if a design model can be constructed without any coordination messages. We study some problems which prevent direct realizability, such as strict sequence, non-local choice, non-deterministic choice, termination race, and others, and show under which conditions these problems are absent and the global model is directly realizable. For the other cases, we show how a conforming design model can be obtained by introducing a minimal number of coordination messages. In this context, we also show under which conditions sequence numbers are required in the messages of a weak while loop. Then we study the automatic derivation of a distributed design model using a tool. In order to obtain an easily readable notation for the global requirements model, we adapt the HMSC notation to the UML Hierarchical State Machine (HSM) notation and extend this notation to describe the roles that participate in the actions of each state of the global behavior. A simple state represents some local actions of a single role, while a hierarchical state usually represents a collaboration between several roles. Then we describe a derivation algorithm that can be applied to a global model written in this proposed HSM notation and generates a distributable UML HSM model, which contains a hierarchical state machine for each role of the application. We implemented this derivation algorithm as a tool in the context of the Umple UML development environment. This tool takes a global requirements model written in the extended HSM notation as input and automatically generates a UML HSM model. The distributed implementation environment described in Zakariapour’s thesis is used for generating a distributed Java implementation, where each distributed component contains one Java run-time environment and realizes the behavior of one or several of the roles of the application. A Travel Management System illustrative example has been discussed to illustrate the representation of the global model using the extended HSM notation and to demonstrate the correctness of the generated design models by the tool.

Actualmente, la ingeniería de software ha propuesto múltiples técnicas para mejorar el desarrollo de software, sin embargo, la meta final no ha sido satisfecha. En muchos casos, el producto software no satisface las necesidades reales de los clientes finales del negocio donde el sistema operará. Uno de los problemas principales de los trabajos actuales es la carencia de un enfoque sistemático para mapear cada concepto de modelado del dominio del problema (modelos organizacionales), en sus correspondientes elementos conceptuales en el espacio de la solución (modelos conceptuales orientados a objetos). El principal objetivo de esta tesis es proveer un enfoque metodológico que permita generar modelos conceptuales y modelos de requisitos a partir de descripciones organizacionales. Se propone el uso de tres disciplinas, distintas pero complementarias (modelado organizacional, requisitos de software y modelado conceptual) para lograr este objetivo. La tesis describe un proceso de elicitación de requisitos que permite al usuario crear un modelo de negocios que representa la situación actual del negocio (requisitos tempranos). Nosotros consideramos que este modelo, el cual refleja la forma en la que se implementan actualmente los procesos de negocio, es la fuente correcta para determinar la funcionalidad esperada del sistema a desarrollar. Se propone también un proceso para identificar los elementos que son relevantes para ser automatizados a partir del modelo de negocio. Como resultado de este proceso se genera un modelo intermedio que representa los requisitos del sistema de software. Finalmente, presentamos un conjunto de guías sistemáticas para generar un esquema conceptual orientado a objetos a partir del modelo intermedio. Nosotros también exploramos, como solución alternativa, la generación de una especificación de requisitos tardíos a partir del modelo intermedio. / Martínez Rebollar, A. (2008).
