Application of an Enterprise Modelling approach to deploy Systems Engineering processes in large organizations

Enterprise Modelling (EM) enables the representation of companies' activities, of their resources along with their roles and responsibilities in order to share the company's knowledge and support performance analysis. For this, EM promotes various concepts, techniques, frameworks, modelling languages and tools today widely used in companies. Currently, even a partial model of an enterprise constitutes a way to communicate, to share advices, to analyse and to make decisions. Therefore, EM appears to be a privileged tool to support any business change management. In a complementary way, Systems Engineering (SE) is a tried and tested methodological approach to design and test new products whatever their complexity or nature. Nowadays SE is considered in industry as a competitive and structured approach enabling a company to manage design activities and more generally to improve its capacity and ability to design complex systems efficiently. SE acts as a model-based engineering approach and promotes to this end a set of standardized collaborative processes, modelling languages and frameworks. Thus, when considering large companies designing complex systems such as a helicopter manufacturer, first it appears critical to be able to adapt processes proposed by SE standardization according to the business specific needs. This tailoring must be guided in order to consider the inherent complexity of the organization, the various human actors' profiles and skills, tools and stakeholders involved in the design of new products. As they all have to communicate and interact efficiently together their abilities and capacities to be interoperable i.e. to really work together should be analysed and improved accordingly before going further. Then, it appears necessary to prepare the company for the required changes, and to deploy in situ the adopted SE processes taking into account not only company's classical constrains and objectives but also the current level of interoperability of its elements. Finally, company managers must become able to control and adjust these processes from the cradle to the grave according to feedbacks from their stakeholders. To support all these activities, Enterprise Modelling (EM) provides several techniques, modelling languages, reference models and interoperability assessment methods which have been adapted and applied in this research work. The purpose of this article is threefold: 1) to provide a state of the art in interoperability, Systems Engineering (SE), and EM to illustrate how these disciplines are interrelated, to identify the needs they imply in the deployment, to discuss lacks in existing works considering these needs and thus to formulate how we aim to meet them, 2) to present an approach based on EM helping companies to lead changes required to apply SE principles and aiming to promote interoperability; and 3) to introduce the modelling environment proposed to support the approach including an ontology, an extension of BPMN 2.0 and software tools

Customizable Interoperability Assessment Methodology To Support Technical Processes Deployment In Large Companies

International audienceIncreasing competition on markets induces a vital need for companies to improve their efficiency and reactivity. For this, a solution is to deploy, improve and manage their processes while paying a special attention on the abilities of the resources those involve. Particularly, the interoperability of the latter is considered in this article as a challenge conditioning the success of the deployment. Consequently, this paper presents a methodology to assess interoperability of people, material resources and organisation units involved or that could be involved in a process, all along the deployment effort. This methodology is usable for prevention, detection and correction of interoperability problems

A Maturity Model for the Deployment of Systems Engineering Processes

Abstract- Nowadays, increasing competition on markets forces companies to improve constantly their competitiveness. For this, they have to control not only the design cycles of their products thanks to an efficient and responsive organization, but also interactions between people, processes and technologies involved in design. However, it is problematic considering the increasing complexity of products. A solution is to apply the principles of Systems Engineering (SE), a proven interdisciplinary approach that defines an effective organization in the form of processes. However it raises a set of questions such as: how to define SE compliant processes including business specificities and how to know if the company has the required organization and skills to deploy them successfully? This article aims to answer this last question for large companies designing complex products under the assumption that interoperability, i.e. the ability to work efficiently together, is a deployment key factor. On the basis of a survey of existing contributions applicable to the deployment, we introduce an innovative maturity model to be used before any deployment action. This paper explains the design approach used to elaborate and validate it, presents its content and shows how to use it

A notation to measure and improve efficiency with regards to Integration, Validation and Verification of systems - Integration Verification Validation Assessment Notation (IV²AN)

International audienceIntegration, Verification & Validation processes are key activities regarding the Quality, Cost and Delivery time, and thus has a huge impact on the projects profitability. IVV processes are complex and have to take into account in a coherent way various elements such as skills, organizations, means, process and risk management. Therefore, a maturity model is well adapted to describe how to evaluate and improve an industrial context. In order to help managers to assess their IVV process and reach a performance level corresponding to their goal, an assessment notation has been carried out (IV²AN). As the main idea is to improve step by step and not to jump directly to the higher level, the assessment notation proposes some ideas for a smooth deployment to improve and gain in development performance. This paper describes this approach, based on criteria which seem important to the INCOSE's French Chapter (AFIS) IVVQ Working Group and shared by several industrial companies

TCE and CrVI source zone treatment by innovative formulation of NZVI

NANOFREZES collaborative research program aims to develop an optimized formulation of Nanoscopic Zero Valent Iron (NZVI) using an innovative organic coating and preparation. Batch tests shows 99% abatement of TCE in 34 days for coated NZVI in comparaison with 11 days with bare NZVI. However, column test with real soil matrix indicate 67 % transfer of coated NZVI whereas only few percent of bare NZVI migrated through the column. These laboratory results indicate that it could be possible to increase significantly radius of injection (ROI) while high reactivity is maintained. This could limitate treatment wells and thus decreases in situ remediation costs. Complementary tests have also shown total reduction and immobilization of CrVI after coated NZVI addition. The new formulation of NZVI will be tested on a 5m x 5m source zone of TCE and CrVI located on a site in South France. First injection will be carried out on a single well with combined suspension of coated NZVI and bromide tracer. Many downstream wells will be monitored 2 times a month up to the second injection 3 month later for complete source zone treatment. Monitoring is planned up to 3 months after second injection. First injection is planned in July and will be the first official attempt of NZVI in situ injection in France

Traitement d’une zone source en TCE et CrVI par injection de nanoparticules de Fer Zéro Valent optimisées

L'injection de fer zéro-valent (ZVI) à l'échelle nanométrique constitue la base d'une nouvelle génération de techniques de dépollution in situ des sols et des eaux souterraines. Le projet NANOFREZES est un projet de recherche collaboratif ayant pour objectif de développer une formulation optimisée de nanoparticules de fer zéro valent en utilisant un enrobage spécifique permettant de maximiser dans le même temps la réactivité et le potentiel de migration en milieu poreux. L’innocuité des nanoparticules enrobées pour l’homme et le milieu récepteur a également été étudiée. Une dernière tâche du projet a consisté à développer et optimiser les méthodes d’injection in situ sur un site atelier dans le cadre d’un essai de traitement d’une zone source mixte de TCE et Cr(VI). Les résultats obtenus au droit de la zone source de pollution sont très satisfaisants : - Un potentiel redox, représentatif du caractère réactif et réductif des nano-Fe(0), très électronégatif (jusqu’à – 700 mV) pendant 4 mois, - Un abattement de 89 à 98 % des teneurs en TCE sans production détectable de chlorure de vinyle et de DCE, - Un abattement total des teneurs en Cr(VI), - Pas d’effet rebond jusqu’à présent
