A elaboração desta metodologia foi realizada a partir de um estudo do papel do agente dentro da Engenharia de Software e da análise de diversas metodologias orientadas a agentes encontradas na literatura, enfocando-se principalmente em três destas: MaSE (Muitiagent Systems Engimering Metkodoiogy), Prornetheus e Tropos, além da linguagem de modelagem AÜML {Agem Vnijied Modeling Language). A Metodologia Unificada proposta visa aproveitar o que há de melhor nestas metodologias, buscando elementos comuns a todas elas, de modo análogo ao que ocorreu com a metodologia unificada (RUP - Raiional Unified Process) em sistemas orientados a objetos. Para validar a Metodologia Unificada e analisar as demais metodologias, um estudo de caso foi modelado. A Metodologia Unificada se mostrou eficiente no projeto, documentação e construção de sistemas multi-agentes, sendo considerada uma metodologia detalhada e mais completa por cobrir os estágios de especificação de requisitos, de análise e de projeto no desenvolvimento de software orientados a agentes / Abstract: This work proposes a Unified Methodology for the development of agent-oriented systems. The methodology was elaborated based on a study of agent's role within software engineering and the analysis of different agent-based software development methodologies found in the literature, focusing in three main ones: MaSE (Muitiagent Systems Engineering Methodology), Prometheus and Tropos, in addition to the modeling language AUM.L (Agent Unified Modeling Language). The Unified Methodology aims at taking advantage of the best from each methodology, searching for common elements among them, in an effort similar to what happened with the Unified Methodology (RUP - Rational Unified Process) in object-oriented systems. To validate the Unified Methodology and analyze the other methodologies, a case study was developed. The Unified Methodology has shown to be efficient in the design, documentation and construction of multi-agent systems. We conclude it to be a detailed and more complete methodology, covering requirements specification, analysis and design stages of agent-based software development / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

A Engenharia de Software evolui gradativamente para uma disciplina científica baseada em observação, formulação teórica e experimentação. Nesse contexto, estudos experimentais têm sido conduzidos para proporcionar evidências sobre a qualidade e a produtividade de técnicas, ferramentas e métodos de desenvolvimento de software. Porém, resultados obtidos a partir de pesquisas experimentais são úteis somente se os pesquisadores puderem consolidá-las em um contexto significativo de conhecimento. O projeto Readers: A Collaborative Research to Develop, Validate and Package Reading Techniques for Software Defect Detection aborda diversos aspectos envolvidos na construção de um corpo significativo de resultados a partir de experimentos controlados. Nesse contexto, sustenta-se que a aplicação de meios alternativos de análise e exploração de dados dos experimentos conduzidos pode colaborar para a evolução do Pacote de Laboratório, e como efeito colateral, contribuir com a formação do corpo de conhecimento almejado. Este projeto propõe mecanismos para integrar técnicas de visualização exploratória à análise de dados de experimentos controlados. Para isso, foram propostas adequações ao processo de experimentação, bem como um processo de visualização para Engenharia de Software Experimental ? V iDAESE. Para ilustrar o V iDAESE, ciclos de análises são apresentados, juntamente com as conclusões obtidas em cada um. As análises visuais apóiam o processo de consolidação de conhecimento a partir dos dados e a melhoria do Pacote de Laboratório. Adicionalmente, uma abordagem para simulação de dados experimentais foi proposta, permitindo explorar cenários que apóiem o planejamento de experimento. / A Engenharia de Software evolui gradativamente para uma disciplina científica baseada em observação, formulação teórica e experimentação.

This software engineering thesis addresses three main issues. When creating the risk documents for this master thesis project, we became even more aware of the problems with categorization and formulation of risk statements and the scope is now focusing on categorization and formulation as a necessity for Experience based Risk Management (EbRM). The EbRM process is the foundation of the thesis and the categorisation and formulation parts had to be solved before implementing the EbRM model. To give the reader a notion about the background of this work, a brief introduction to the Experience based Risk Management model is given in the thesis. The thesis is based on literature studies, experiences and experiments. The formulation system is gathered from the Software Engineering Institute (SEI) and is called the CTC-format (Condition, Transition, Consequence). This format allows you to separate conditions and consequence of the risk and thereby provides you with easier categorisation and understandability. The categorisation system used is the SEI Taxonomy Based Categorisation (TBC). A categorisation system built as a search tree where each leaf represents a rather narrow risk domain. In order to evaluate those two different systems we performed an experiment showing that the combination thereof gave a much higher match in sorting risks between different groups. The conclusions of this work are that the TBC in connection with the CTC structure forms a very good basis for risk management when it comes to categorisation and formulation. In addition to properly formulated and tagged names and a thorough process when identifying and documenting risks, the risk management will be facilitated by using our conclusions in further risk management. Oral information must as well be on a sufficient level to gain full benefits from a risk management process.

This thesis is intended to deal with questions related to the processing of naturally occurring texts, also known as natural language processing (NLP). The subject will be approached from a software engineering perspective, and the problem description will be formulated thereafter. The thesis is roughly divided into two major parts. The first part contains a literature study covering fundamental concepts and algorithms. We discuss both serial and parallel architectures, and conclude that different scenarios call for different architectures. The second part is an empirical evaluation of an NLP framework or toolkit chosen amongst a few, conducted in order to elucidate the theoretical part of the thesis. We argue that component based development in a portable language could increase the reusability in the NLP community, where reuse is currently low. The recent emergence of the discovered initiatives and the great potential of many applications in this area reveal a bright future for NLP.

Many organizations are moving towards Global Software Engineering and Global Development is becoming a major trend. Global Software Engineering comes with its own set of challenges that may affect projects in a negative way. However, it is still becoming increasingly popular among organizations because of its lure of cheap labour, portrayal of a global presence and a diverse talent/labour pool of resources that the organizations get to select from. The need for evaluating the processes of these global organizations has also grown and a number of Software Process frameworks are being designed and restructured to help cover the gap of evaluating these processes in a global environment. This thesis aims to examine one popular Software Process framework i.e. the ISO 9001:2000 TickIT. The authors provide informed recommendations of how and where the TickIT guide can incorporate various aspects of Global Software Engineering in its guidelines. The empirical validation of this research consisted of both interviews and surveys. The interviews were conducted with TickIT auditors working in the fields of Global Software Engineering and Software Process Improvement. These interviews provided insight into the minds of the people already working in the global software domain. The survey was in the form of an online questionnaire that was sent out to TickIT auditors from the United Kingdom and Sweden. Their replies were analyzed and the final informed recommendations for the TickIT guidelines were provided based on both the interview replies and the questionnaire analysis. / Many organizations are moving towards Global Software Engineering and Global Development is becoming a major trend.

Context. Decision-making is a significant step in development process of software engineering. Evidence-based Software Engineering has been one of the strategies attempting to facilitate decision-making process. It follows process of gathering suitable evidence in the aim of making a viable use the evidence. Objectives. In this study, evidence use in practice was mainly focused as a part of which barriers and facilitators concerning it were aspired to be obtained from the practitioners. Concerning existing evidence, it was also aimed in finding out and gathering the existing evidence in software engineering, as a contribution to the evidence use in practice. Methods. To obtain the outcomes for the specified objectives, an extensive tertiary study and 18 interviews were conducted. The tertiary study was replication of study by Kitchenham et al. [1]. It was also an updated version for the years of 2010 to 2016. The interviews were conducted among the software practitioners from several types of industries and regions. Results. 67 SLRs were analysed and extracted to gather and obtain existing evidence. 18 interviews were conducted among software practitioners to assess barriers and facilitators to evidence use in making decisions. Conclusions. We conclude from results of tertiary study that the research studies in every sub-domain are available under software engineering and are even increasing year by year. From the analysed results of the semi-structured interviews, it was clear that the implementation of research results in practice is inter-dependant on many major as well as trivial factors concerning the practitioners.

Search Based Software Engineering is one of the important field of software engineering. Over the past few years even though there is a lot of study performed on SBSE and its search techniques in software development areas, it appears SBSE is not very industry relevant at the moment because most of the academic work was limited towards the application of search techniques. Hence, author proposes a study to know the trend of SBSE literature over the past few years and also analyze to what degree current SBSE research is industry relevant

This thesis investigates the deployment modeling in the scope of Progress,a research vision that aims to tackle the increasing complexity of embedded softwaresystems by adopting a software-component approach. The first phase of the Progress deployment process, which is in the focus of this thesis, defines virtualnodes architecture as an abstraction of target platform devices where componentsare allocated. Based on the Progress development process analysis, the thesis identifiesconcerns that need to be addressed by the ProCom component model to supportthe concepts of virtual nodes and allocation, proposes the extension of the ProCommeta-model and the design of allocation in general. The thesis also provides an implementation of a tool support incorporated into the Eclipse application that forms the basis of the Progress IDE. The implementation,whose main goals are to prove the correctness of the ideas and alleviate the deployment in the IDE, integrates rich graphical editors that support the modelingof virtual platform and allocation of components. / Progress

This thesis is focused on the attributes concept of ProCom, a component model developed within The Progress Centre for Predictable Embedded Software Systems. Attributes are pieces of information of various types and levels of abstraction associated with the ProCom entities during the development of a system. Based on the analysis of the development process envisioned by Progress, the requirements for the attributes of ProCom entities are identified, and various alternatives of realizing attributes are analyzed. The chosen solution of highly structured, multi-valued, and extensible attributes is elaborated. The thesis also consists of the design and the prototype implementation of an attribute framework realizing and proving the feasibility of the proposed concepts. The framework addresses the needs of all actors involved in working with attributes throughout the development of a system: It provides an extensible, modular GUI for viewing and editing possibly highly complex information contained in attributes, an interface for the programmatic access to attributes, and well-defined mechanisms for extending the attribute pool by new attributes, new attribute types, and means for their manipulation. The framework is integrated into the main tool supporting the Progress development, the Progress IDE. / Progress

The unit RTH, Radio Access Network Transmission and Home at Ericsson site in Linkoping uses today different test tool which are divided between different projects. Today they do not have any optimal solution for in an easy way execute the test cases from different projects concurrently, and share the test tools between the these projects. All the execution of test cases which a test tool is needed needs to be configured and started manually which cost both time and money. Since the test tools are very expensive to use, it is desirable to increase the utilization. The purpose of this thesis is to provide RTH a working prototype which can in an intelligent way schedule and then automatically execute the test cases. The prototype shall consist of a web user interface and a scheduler part. The web user interface is going to be that part which the user works in, and the scheduler handles the prioritization and make sure that the test cases are executed. To reach the goal with a working prototype, PHP and Java were picked as framework for the prototype. The theory behind these programming languages and more can be read in the theory chapter, and all the different methods which were used. The result of the working process can be read in the Result chapter. The end prototype fulfills the customer’s requirement. Improvement and new functionalities are given as suggestion at the end of this thesis, where we also discuss the working process.
