Proposition d'un cadre méthodologique pour le management intégré des risques et des processus d'entreprise / A Methodological framework for the integrated management of risks and business processes

Sienou, Amadou 26 June 2009 (has links)
L'ingénierie d'entreprise conçoit et met en application des projets d'amélioration de la structure et du fonctionnement des organisations de production de biens ou de services. Elle développe des démarches fondées sur la modélisation, en particulier la modélisation des processus métiers, pour assurer une qualité et une cohérence d'ensemble des projets. Aujourd'hui, la prise en compte du risque en ingénierie d'entreprise fait l'objet de nombreux développements, liés à un environnement perçu comme de plus en plus agressif et imprévisible. Des cadres de référence sont même publiés pour guider les entreprises dans ces nouvelles dimensions du pilotage de l'organisation autour du risque. Notre étude se consacre à la conception des processus métier dirigée par les risques comme une composante à part entière de l'ingénierie d'entreprise. Après avoir fait une synthèse des connaissances sur les univers du risque et des processus, un problème d'intégration de ces connaissances est formulé. Un cadre méthodologique pour le management intégré des risques et des processus est ainsi conçu et décrit. Il repose sur la coordination des cycles de vie de la gestion des risques et de la gestion des processus métier, sur la définition d'un cadre conceptuel unifié permettant d'identifier et de maîtriser les informations échangées entre eux, et enfin sur un langage de modélisation adapté à une description des situations et étendant les capacités d'un outil de modélisation du marché (ARIS Business Architect). Un cas d'études du domaine de la santé vient illustrer le bien fondé de l'application de ce cadre méthodologique sur un cas concret. / Enterprise engineering is concerned with the design of projects which aim to improve the structure and behaviour of organisations producing goods and services. It develops approaches based on modelling techniques, particularly on business process modelling in order to assure the quality and the global consistency of the project portfolio. Nowadays, risk consideration in enterprise engineering is a growing importance since the business environment is becoming more and more competitive and unpredictable. In fact, reference frameworks providing guidance for enterprise risk management are developed to tackle this. Our research focuses on risk driven business process design as an integral part of enterprise engineering. After delivering a synthesis of work related to risks and business processes, a research question concerning the integration of both has been addressed. A framework for the integrated management of risks and business processes is suggested. It is based on three components: a coordination of risk and business process management lifecycles, a unified conceptual framework supporting information exchanges between the coordinated lifecycles, and finally a modelling language adapted to the description of risky situations. The later extends the features of a commercial modelling tool (ARIS Business Architect). A case study from the health sector illustrates the foundation of the methodological framework.

Articulating design-time uncertainty with DRUIDE

Dhaouadi, Mouna 09 1900 (has links)
Les modélisateurs rencontrent souvent des incertitudes sur la manière de concevoir un modèle logiciel particulier. Les recherches existantes ont montré comment les modélisateurs peuvent travailler en présence de ce type d' ''incertitude au moment de la conception''. Cependant, le processus par lequel les développeurs en viennent à exprimer leurs incertitudes reste flou. Dans cette thèse, nous prenons des pas pour combler cette lacune en proposant de créer un langage de modélisation d'incertitude et une approche pour articuler l'incertitude au moment de la conception. Nous illustrons notre proposition sur un exemple et l'évaluons non seulement sur deux scénarios d'ingénierie logicielle, mais aussi sur une étude de cas réel basée sur les incertitudes causées par la pandémie COVID-19. Nous menons également un questionnaire post-étude avec les chercheurs qui ont participé à l'étude de cas. Afin de prouver la faisabilité de notre approche, nous fournissons deux outils et les discutons. Enfin, nous soulignons les avantages et discutons des limites de notre travail actuel. / Modellers often encounter uncertainty about how to design a particular software model. Existing research has shown how modellers can work in the presence of this type of ''design-time uncertainty''. However, the process by which developers come to elicit and express their uncertainties remains unclear. In this thesis, we take steps to address this gap by proposing to create an uncertainty modelling language and an approach for articulating design-time uncertainty. We illustrate our proposal on a worked example and evaluate it not only on two software engineering scenarios, but also on a real case study based on uncertainties caused by the COVID-19 pandemic. We also conduct a post-study questionnaire with the researchers who participated in the case study. In order to prove the feasibility of our approach, we provide two tool supports and discuss them. Finally, we highlight the benefits and discuss the limitations of our current work.

Communication of sustainability information and assessment within BIM-enabled collaborative environment

Zanni, Maria Angeliki January 2017 (has links)
Sustainable performance of buildings has become a major concern among construction industry professionals. However, sustainability considerations are often treated as an add-on to building design, following ad hoc processes for their implementation. As a result, the most common problem to achieve a sustainable building outcome is the absence of the right information at the right time to make critical decisions. For design team members to appreciate the requirements of multidisciplinary collaboration, there is a need for transparency and a shared understanding of the process. The aim of this study is to investigate, model, and facilitate the early stages of Building Information Modelling (BIM) enabled Sustainable Building Design (SBD) by formalising the ad hoc working relationships of the best practices in order to standardise the optimal collaboration workflows. Thus, this research strives to improve BIM maturity level for SBD, assisting in the transition from ad hoc to defined , and then, to managed . For this purpose, this study has adopted an abductive research approach (iterative process of induction and deduction) for theory building and testing. Four (4) stages of data collection have been conducted, which have resulted in a total of 32 semi-structured interviews with industry experts from 17 organisations. Fourteen (14) best practice case studies have been identified, and 20 incidents narratives have been collected applying the Critical Decision Method (CMD) to examine roles and responsibilities, resources, information exchanges, interdependencies, timing and sequence of events, and critical decisions. As a result, the research has classified the critical components of SBD into a framework utilising content and thematic analyses. These have included the definition of roles and competencies that are essential for SBD along with the existing opportunities, challenges, and limitations. Then, Schedules of Services for SBD have been developed for the following stages of the RIBA Plan of Work 2013: stage 0 (Strategic Definition), stage 1 (Preparation and Brief), and stage 2 (Concept Design). The abovementioned SBD components have been coordinated explicitly into a systematic process, which follows Concurrent Engineering (CE) principles utilising Integrated DEFinition (IDEF) structured diagramming techniques (IDEF0 and IDEF3). The results have identified the key players roles and responsibilities, tasks (BIM Uses), BIM-based deliverables, and critical decision points for SBD. Furthermore, Green BIM Box (GBB) workflow management prototype tool has been developed to analyse communication and delivery of BIM-enabled SBD in a centralised system (Common Data Environment, CDE). GBB s system architecture for SBD process automation is demonstrated through Use Case Scenarios utilising the OMG UML (Object Management Group s Unified Modelling Language) notation. The proposed solution facilitates the implementation of BIM, Information Communication Technology (ICT), and Building Performance Analysis (BPA) software to realise the benefits of combining distributed teams expertise holistically into a common process. Finally, the research outcomes have been validated through academic and industrial reviews that have led to the refinement of the IDEF process model and framework. It has been found that collaborative patterns are repeatable for a variety of different non-domestic building types such as education, healthcare, and offices. Therefore, the research findings support the idea that a detailed process, which follows specified communication patterns, can assist in achieving sustainability targets efficiently in terms of time, cost, and effort.

Las contribuciones específicas son: - Definición de un método para ejecutar ECs sobre una base de datos de SNOMED CT orientada a grafos. - Definición de métodos para simplificar ECs antes y después de su ejecución, y su validación semántica conforme al Machine Readable Concept Model de SNOMED CT (MRCM). - Definición de un método para visualizar, explorar dinámicamente, comprender y validar subconjuntos de SNOMED CT. - Desarrollo de SNQuery, una plataforma que ejecuta, simplifica y valida ECs y visualiza los subconjuntos resultantes. - Definición de EHRules, un lenguaje de expresiones basado en el openEHR Expression Language para la especificación de reglas de consistencia en arquetipos, incluido el enlace terminológico de contenido, con el fin de enriquecer los arquetipos con conocimiento del dominio. - Definición de un método para ejecutar las expresiones de EHRules con el fin de validar la consistencia de los datos de la HCE mediante la ejecución de dichas expresiones sobre instancias de datos de pacientes. Nuestro objetivo es que estas contribuciones ayuden a mejorar la calidad de la HCE, ya que proporcionan métodos y herramientas para la validación y mejora de la consistencia de los datos de la HCE. Pretendemos, además, mediante la definición de enlaces de contenido entre modelos de información y terminologías clínicas, elevar el nivel de interoperabilidad semántica, para lo cual la definición de enlaces terminológicos es crucial. / [CA] La consistència de les dades de la HCE, com a dimensió de la qualitat, es considera un requisit essencial per a la millora de la prestació de l'assistència sanitària, els processos de presa de decisions clíniques i la promoció de la investigació clínica.

In this context, cooperation between information and domain models has been considered essential in the literature, but it has not been adequately addressed by the scientific community to date. The main contribution of this thesis is the development of methods and tools for the inclusion of terminology binding expressions in consistency rules. Specific contributions are: - Definition of a method to execute ECs over a SNOMED CT graph-oriented database. - Definition of methods to simplify ECs before and after its execution and semantic validation according to the SNOMED CT Machine Readable Concept Model (MRCM). - Definition of a method to visualize, dynamically explore, understand and validate SNOMED CT subsets. - Development of SNQuery, an execution platform that executes, simplifies and validates ECs, and visualizes the resulting subsets. - Definition of EHRules, an expression language based on the openEHR Expression Language for the specification of consistency expressions in archetypes, including value set bindings, in order to enrich archetypes with domain knowledge. - Definition of a method to execute EHRules expressions in order to validate the consistency of EHR data by executing such rules over patient data instances. Our objective is that these contributions help to enhance the quality of EHR, as they provide methods and tools for the validation and enhancement of the EHR data consistency. We also intend, by defining value set bindings between information models and clinical terminologies, to raise the level of semantic interoperability, for which the definition of terminological bindings is crucial. / This thesis was partially funded by Ministerio de Economía y Competitividad, “Doctorados Industriales”, grant DIN2018-009951, and by Universitat Politècnica de València, “Formación de Personal Investigador” (FPI-UPV). / Giménez Solano, VM.

Combining Business Intelligence, Indicators, and the User Requirements Notation for Performance Monitoring

Johari Shirazi, Iman 26 November 2012 (has links)
Organizations use Business Intelligence (BI) systems to monitor how well they are meeting their goals and objectives. Yet, very often BI systems do not include clear models of the organization’s goals or of how to measure whether they are satisfied or not. Several researchers now attempt to integrate goal models into BI systems, but there are still major challenges related to how to get access to the BI data to populate the part of the goal model (often indicators) used to assess goal satisfaction. This thesis explores a new approach to integrate BI systems with goal models. In particular, it explores the integration of IBM Cognos Business Intelligence, a leading BI tool, with an Eclipse-based goal modeling tool named jUCMNav. jUCMNav is an open source graphical editor for the User Requirements Notation (URN), which includes the Use Case Map notation for scenarios and processes and the Goal-oriented Requirement Language for business objectives. URN was recently extended with the concept of Key Performance Indicator (KPI) to enable performance assessment and monitoring of business processes. In jUCMNav, KPIs are currently calculated or modified manually. The new integration proposed in this thesis maps these KPIs to report elements that are generated automatically by Cognos based on the model defined in jUCMNav at runtime, with minimum effort. We are using IBM Cognos Mashup Service, which includes web services that enable the retrieval of report elements at the most granular level. This transformation provides managers and analysts with useful goal-oriented and process-oriented monitoring views fed by just-in-time BI information. This new solution also automates retrieving data from Cognos servers, which helps reducing the high costs usually caused by the amount of manual work required otherwise. The novel approach presented in this thesis avoids manual report generation and minimizes any contract with respect to the location of manually created reports, hence leading to better usability and performance. The approach and its tool support are illustrated with an ongoing example, validated with a case study, and verified through testing.
