[pt] A aplicação de técnicas de workflows na área de computação científica é bastante explorada para a condução de experimentos e construção de modelos in silico. Ao analisarmos alguns desafios enfrentados por uma aplicação científica na área de geociências, percebemos que workflows podem ser usados para representar os modelos gerados na aplicação e facilitar o desenvolvimento de funcionalidades que supram as necessidades identificadas. A maioria dos trabalhos e ferramentas na área de workflows científicos, porém, são voltados para uso em ambientes de computação distribuída, como serviços web e computação em grade, sendo de difícil uso ou integração dentro de aplicações científicas mais simples. Nesta dissertação, discutimos como viabilizar a composição e representação de workflows dentro de uma aplicação científica existente. Descrevemos uma arquitetura conceitual de motor de workflows voltado para o uso dentro de uma aplicação stand-alone. Descrevemos também um modelo de implantação em uma aplicação C plus plus usando redes de Petri para modelar um workflow e funções C plus plus para representar as tarefas. Como prova de conceito, implantamos esse modelo de workflows em uma aplicação existente e analisamos o impacto do seu uso na aplicação. / [en] The use of workflow techniques in scientific computing is widely adopted in the execution of experiments and building in silico models. By analysing some challenges faced by a scientific application in the geosciences domain, we noticed that workflows could be used to represent the geological models created using the application so as to ease the development of features to meet those challenges. Most works and tools on the scientific workflows domain, however, are designed for use in distributed computing contexts like web services and grid computing, which makes them unsuitable for integration or use within simpler scientific applications. In this dissertation, we discuss how to make viable the composition and representation of workflows within an existing scientific application. We describe a conceptual architecture of a workflow engine designed to be used within a stand-alone application. We also describe an implementation model of this architecture in a C plus plus application using Petri nets to model a workflow and C plus plus functions to represent tasks. As proof of concept, we implement this workflow model in an existing application and studied its impact on the application.

There has been an increased focus in recent years on the development of re-usable software, in the form of objects and software components. This increase, together with pressures from enterprises conducting transactions on the Web to support all business interactions on all scales, has encouraged research towards the development of easily reconfigurable and highly adaptable Web services. This work investigates the ability of Component-Based Software Development (CBSD) to produce such systems, and proposes a more manageable use of CBSD methodologies. Component-Driven Software Development (CDSD) is introduced to enable better component manageability. Current Web service technologies are also examined to determine their ability to support extensible Web services, and a dynamic Web service architecture is proposed. The work also describes the development of two proof-of-concept systems, DREW Chat and Hamilton Bank. DREW Chat and Hamilton Bank are implementations of Web services that support extension dynamically and at run-time. DREW Chat is implemented on the client side, where the user is given the ability to change the client as required. Hamilton Bank is a server-side implementation, which is run-time customisable by both the user and the party offering the service. In each case, a generic architecture is produced to support dynamic Web services. These architectures are combined to produce CREWS, a Component-driven Runtime Extensible Web Service solution that enables Web services to support the ever changing needs of enterprises. A discussion of similar work is presented, identifying the strengths and weaknesses of our architecture when compared to other solutions.

Thesis (MTech (Business Information Systems))--Cape Peninsula University of Technology, 2015. / The objective of the thesis is to determine the role Business Informatics plays in transforming an organisation using a selected organisation in Cape Town as a case study. Business informatics is an emerging discipline that combines various aspects of business management, information technology and informatics. Informatics is broadly defined as the science of processing information; thus, increasingly, it involves processing and analysing information digitally with the aid of computers. Therefore the aim of the research was to understand what components of business informatics are being leveraged to transform businesses, and the challenges thereof. This was done using a social theory – duality of technology from Orlikowski adapted from Giddens’ Structuration Theory (ST) as a theoretical framework, particularly, the dimensions of duality of structure. The theory was used as a lens to understand and interpret this social phenomenon - the role business informatics can play in business transformation. It is argued that business informatics concepts are able to assist in business transformation through effective use of information systems and business management concepts. In that regard, ERP system in a Cloud platform was recommended to illustrate these concepts. The concepts helped to device guidelines for determining the challenges of a business to use informatics to transform and become sustainable and competitive. Therefore, the research explained and recommended why business entities have begun to move from an application-based enterprise resource planning (ERP) system to cloud computing-based ERP (cloud-ERP) system. The study used the interpretive approach where qualitative philosophy was applied together with the underpinning theory and literature reviewed to design a semi-structured interview schedule as a data collection instrument. It was a case study of an Organisation where the units of analysis were the IT, Finance, HR and Sales and Marketing departments and object of analysis was 50 employees. The output is a general framework to guide businesses as to how to apply the concepts of business informatics to achieve improved business transformation.

Les entreprises évoluent aujourd’hui dans un environnement complexe, dynamique et en constante évolution. Leur compétitivité et leur pérennité dépendent de leur agilité et de leur capacité à satisfaire les exigences des différentes parties prenantes.La problématique générale de ce travail peut se formuler comme suit : « comment garantir la création de valeur d’une entreprise pour ses différentes parties prenantes en maîtrisant les risques liés à l’évolution de ses activités et de son environnement ? ». Nous proposons une méthode dynamique et systémique de reconception des processus orientée création de valeurs et intégrant les risques liés au système et à son environnement : SCOS’R2 (Systemics for Complex Organisational Systems’ Reengineering and Risk).Cette méthode repose sur une démarche en quatre étapes ; identifier les sous-systèmes à reconcevoir à travers l’identification des facteurs de changements et de de risques ; modéliser la création de valeurs ; déterminer les actions d’amélioration ou de réingénierie à partir de la modélisation de la création de valeurs et de la gestion globale des risques et enfin reconcevoir le sous-système concerné.Pour garantir sa pérennité l’EFS (Etablissement Français du Sang) doit répondre aux différentes exigences des parties prenantes et s’adapter le plus rapidement possible aux changements de l’environnement et aux aléas qui peuvent impacter son fonctionnement.Nous avons donc appliqué cette méthode à l’EFS permettant ainsi de faire face à son environnement incertain, complexe et évolutif. La finalité de cette méthode est d’assurer un niveau de sécurité et de qualité optimal et une amélioration continue de la performance multicritère (qualité, sécurité, médicale, technique, économique,...). La méthode SCOS’R2 a été appliquée aux sous-systèmes de l’EFS les plus impactés par les facteurs de changements et de risques, à savoir le sous-système prélèvement et le sous-système de mise à disposition du plasma matière première pour le LFB (Laboratoire français du Fractionnement et des Biotechnologies). / Contribution to the re-engineering of EFS processes Today businesses operate in a complex and dynamic environment that is constantly changing. Their competitiveness and sustainability depends on their agility and ability to satisfy the requirements of the different stakeholders.The general issue of this work is "how to ensure a company creates value for its various stakeholders by controlling the risks linked to changes in its activities and environment? ». We propose a dynamic and systemic process redesign method, oriented towards value creation and incorporating the risks linked to the system and its environment: SCOS'R2 (Systemics for Complex Organizational Systems' Reengineering and Risk).This method is based on a four-step approach: identify the sub-systems to redesign by identifying the change and risk factors; model value creation; determine the actions for improvement or reengineering based on the value-creation model and the overall risk management; and, finally, re-design the relevant subsystem.To ensure its long-term survival, the EFS must meet the requirements of various stakeholders and adapt as quickly as possible to changes in the environment and to the risks which may affect its operation.Thus, we applied this method to the EFS that will enable it to cope with its uncertain, complex and changing environment. The purpose of this method is to ensure an optimal level of security and quality, together with continuous improvement of multicriteria performance (quality, security, medical, technical, economical, etc., criteria).The SCOS'R2 method was applied to the EFS subsystems most affected by the change and risk factors, namely to the blood collection system and the sub-system for provision of plasma for the LFB (Laboratoire français du Fractionnement et des Biotechnologies).
