Abstract

As economic pressure continues to mount worldwide, closer cooperation is needed between people, companies and even countries. At the same time, the scale of projects is constantly rising. In order to ensure the success of large-scale projects, the way different teams cooperate is becoming increasingly important. Cooperation between systems engineering and project management is now key in this respect. On the other hand, it is widely recognised that the use of standards can improve the success ratio. Thus, integration using standards or guides from systems engineering and project management can help companies improve their competitiveness. A host of standards or guides have already been published in both domains. The purpose of this paper is to take the most frequently used standards or guides from systems engineering and project management, to compare them and build a bridge between them so as to provide a view shared by systems engineers and project managers enabling them to carry out their projects effectively.

Abstract

In the paper process of moving from software requirements to Unified Modeling Language (UML) diagrams has been studied. It shows the importance of this process and discusses many comparative studies in the field. A questionnaire related to the study was distributed worldwide to many research groups, academia, and industry to know the current status of using requirement management tools, knowledge of using UML in software development, frequently used UML diagrams, and the methodology used to generate UML diagrams from requirements. The paper emphasises that there is a need to do some important research in the area of requirements Natural Language processing (NLP) to obtain UML diagrams, and generalize process of using automatic or semi-automatic methodology to generate UML diagrams from requirements.

Abstract

Requirement elicitation is a very important step in to developing any new application. This paper will examine the culture effect on requirement elicitati on in developing countries. This is a unique research that will look at require ment elicitation process in 10 different parts of t he world including Arab word, India, China, Africa and South America. The focus is how the culture affects (RE) and makes every place has its own practice of RE. T he data were collect through surveys and direct interviews. The results show astonishing culture ef fect on RE. The conclusion is that culture effects deeply the t echnique gets chosen for requirement elicitation. I f you are doing RE in Thailand, it will be very different from RE in Arab world. For example in Thailand re spect for leader is critical and any questioning of manag er methods will create a problem while in Arab worl d decision tree is favourite RE technique because vis ual are liked much more than documents.

Abstract

In the current context of increasing time-to-market pressure, innovation has been identified as the major factor of competitiveness. The need to manufacture more new products with restricted resources urges companies to perform innovative design. To be efficient and reduce uncertainty it is necessary to control the design process. In order to simultaneously control and innovate, a new model to manage the design process is required. Within the framework of Systems Engineering, we propose a static design model, which takes into account requirements related to the product, the design process and the organization. Based on this static design model, a dynamic model of innovative design process is developed. It emphasizes the importance to conciliate different requirements to produce innovative products.

Résumé

La modélisation informatique et la simulation sont des activités de plus en plus répandues lors de la conception de systèmes complexes et critiques tels que ceux embarqués dans les avions. Les décisions prises sur la conception de ces systèmes à partir des moyens de simulation doivent être sûres. L’étude a exploré le domaine large variant de moins formelle théorie d’ingénieur de system utilisant ontologies à plus formelle théorie de simulation. Les travaux réalisés sont développement et validation d’ontologie et formalisation de théorie d’inclusion entre domaine de simulation et domaine d’utilisation, définir et développer des méthodes semi-automatiques utilisant de ontologie de Modélisation et Simulation pour identifier et sélectionner une abstraction consistent par rapport aux objectives de simulation, formalisation et raffinement de théorie de relation de simulation et approximatif pour identifier les abstractions des systèmes des transitions avec des ensembles d’états et d’actions finis et approximativement équivalent par rapport aux niveaux de fidélité désiré par le utilisateur de simulation, développement des outils permettant évaluation de fidélité, appliquer la méthode et démontrer la preuve de concept sur des cas d’application fournis par l’entreprise.

Abstract

In using Modeling and Simulation for the system Verification & Validation activities, often the difficulty is finding and implementing consistent abstractions to model the system being simulated with respect to the simulation requirements. A proposition for the unified design and implementation of modeling abstractions consistent with the simulation objectives based on the computer science, control and system engineering concepts is presented. It addresses two fundamental problems of fidelity in simulation, namely, for a given system specification and some properties of interest, how to extract modeling abstractions to define a simulation product architecture and how far does the behaviour of the simulation model represents the system specification. A general notion of this simulation fidelity, both architectural and behavioural, in system verification and validation is explained in the established notions of the experimental frame and discussed in the context of modeling abstractions and inclusion relations. A semi-formal ontology based domain model approach to build and define the simulation product architecture is proposed with a real industrial scale study. A formal approach based on game theoretic quantitative system refinement notions is proposed for different class of system and simulation models with a prototype tool development and case studies. Challenges in research and implementation of this formal and semi-formal fidelity framework especially in an industrial context are discussed.

Abstract

Informal validation techniques such as simulation are extensively used in the development of embedded systems. Formal approaches such as model-checking and testing are important means to carry out Verification and Validation (V&V) activities. Model-checking consists in exploring all possible behaviors of a model in order to perform a qualitative and quantitative analysis. However, this method remains of limited use as it runs into the problem of combinatorial explosion. Testing and model-checking do not take into account the context of use objectives of the model. Simulation overcomes these problems but it is not exhaustive. Submitted to simulation scenarios which are an operational formulation of the V&V activity considered, simulation consists in exploring a subset of the state space of the model. This paper proposes a formal approach to assess simulation scenarios. The formal specification of a model and the simulation scenarios applied to that model serve to compute the effective evolutions taken by the simulation. It is then possible to check whether a simulation fulfills its intended purpose. To illustrate this approach, the application study of an intelligent cruise controller is presented. The main contribution of this paper is that combining simulation objectives and formal methods leads to define a qualitative metric for a simulation evaluation without running a simulation.
