Повний текст джерелаIn the current competitive environment, innovation, quality and costs control are necessary element for companies competitiveness. However, theses element no longer represent effective factors of differentiation and advantageous positioning with regard to clients. Today, companies urgently need to reduce conception, planning and manufacturing delays. They also need to increase they response and anticipation ability in order to improve productivity. Theses new challenges give prominence to the role of the company information system as strategic element which brings potential improvement of performances. Compnies will want to invest in integration tools and control technical data exchange in the production environment tio increase reactivity. The goal of the present work is to specify and make a prototype of a workshop technical monitorin system. Four parts are included in the report: first part compares workshop technical monitoring system with existing systems, second part defines the system specification method, third part gives an object oriented specification of a workshop technical monitoring system, fourth part gives prominence to the technical monitoring system software prototype

Повний текст джерелаThe proposed research work deals with the issues of Simulation Lifecycle Management (SLM). Nowadays numerical simulation plays a major role in the product development process. Indeed, reducing the need for physical prototypes and providing a relevant analysis of system behavior, numerical simulation has became a major lever for improving the development process. Faced to an increased competition, manufacturing companies rely heavily on numerical simulation to improve the technical performances of their products. According to this increasing use of numerical simulation, some issues related to data management and information sharing between simulation disciplines and with other phases of the development process has emerged. This PhD thesis presents a study of improvement of simulation activities based on an application of PLM approach. This study suggests two main areas of improvement. The first one concerns the definition of product structure for better integration of the needs of the numerical simulation, specifically in relation to the definition of fluid and structure domains and also related interactions. The second area is related to the management of dependencies between simulation data for a better traceability and an easier capitalization. This research work finally resulted in the implementation of a SLM prototype based on the solution Smar Team of Dassault Systèmes and coupled with two expert applications : CATIA, a CAD solution of Dassault Systèmes, and Workbench, a Pre/Post-processing solution of Ansys

Повний текст джерелаTime domain electromagnetism (TDEM) allows geophysicists to probe the resistivity of the subsurface as a function of depth. Today the airborne versions of this method can be brought into operation either by helicopter or by large airplanes (fixed wings), both are expensive and the first has the disadvantage of a low autonomy (distance available after take-off), the second of a low resolution. This thesis defends the development of a light system towed by a small airplane allowing both autonomy and resolution while being more affordable. It presents numerical simulations to determine the optimal acquisition parameters (emission waveform, altitude) of the future system. Using these parameters, simulations are also performed to assess the sensitivity of the system in various geological contexts (karst and alluvial deposits) with 1D (tabular) and 3D structure. Both HCP (standard) and VCP configurations are considered. The VCP configuration greatly increases the sensitivity to 3D bodies. A special consideration is afforded to underground storage cases and to the Orgeval (subsidiary of the Seine) hydrologic basin. We also detail the (sometimes problematic) choice of the mechanical and electronic characteristics of the system, such as antenna materials selection, antenna geometries, adaptation of impedance of the transmitting and receiving coils or cable lengths and weights. This approach results in the definition of a complete TDEM system ready for future flight tests

Повний текст джерелаThe geometric tolerancing activity is often postponed until the detailed design stage. The main cause is that most tolerancing tools used in tolerancing activity are based on CAD (Computer Aided Design) modeler representations. To answer to this problem, we purpose a design framework where geometric tolerancing activity is based on a product model. This is in opposition with CAD system architecture where expertises share data with the geometric representation. The presented product model is the result of the IPPOP (Integration Product Process and Organisation for engineering Performance improvement) consortium. It is based on a structure which ensures data traceability during the design process and allows to describe design alternatives. In this work we put the stress on the benefit of the product model use with a tolerancing point of view in opposition with current CAD system use. Two main points are presented: the integration of the tolerancing data in the product data and the traceability of the geometric specifications. The aim of the integration is to enhance the product description with a tolerancing point of view in collaborative design. The traceability allows on the one hand to keep the link between the functional requirements and the geometric specifications and on the other hand to distinguish the geometric specifications induced by a standard component integration
Vekris, Dimitrios. "Vérification de spécifications EB-3 à l'aide de techniques de model-checking." Thesis, Paris Est, 2014. http://www.theses.fr/2014PEST1117/document.
Повний текст джерелаEB-3 is a specification language for information systems. The core of the EB-3 language consists of process algebraic specifications describing the behaviour of entities in a system, and attribute functions that are recursive functions evaluated on the system execution trace describing entity attributes. The verification ofEB-3 specifications against temporal properties is of great interest to users of EB-3. In this thesis, we focus on liveness properties of information systems, which express the eventuality that certain actions take place. The verification of liveness properties can beachieved with model checking. First, we present an operational semantics for EB-3 programs, in which attribute functions are computed during program evolution and their values are stored into program memory. This semantics permits us to define an automatic translation from EB-3 to LNT, a value-passing concurrent language with classical process algebra features. Our translation ensures the one-to-one correspondence between states and transitions of the labelled transition systems corresponding to theEB-3 and LNT specifications. Then, we automate this translation with the EB-3toLNT tool, thus equipping the EB-3 method with the functional verification features available in the model checking toolbox CADP. With the aim of improving the model checking results of this approach, we explore abstraction techniques for information systems specified inEB-3. In particular, we concentrate on a specific family of systems called parametric, whose behaviour is scaled in keeping with the predefined value of a system parameter. Finally, we apply this method on the EB-3 context

Повний текст джерелаA notable part of the faulty operations of the industrial systems is due to specification erros. Validation denotes the set of techniques which aim at preventing such erros. The thesis develops a methodology and its theoretical bases for the validation of communicating automata based specifications. The idea is that a specification can be rewritten in a form which reveals its behaviours, so that the engineer can appreciate the accuracy of it. More technically the rewritten specification is a graph built starting from the consistent control path resulting from the original specification. It is shown that the rewritten specification describes the same system and that it can be substituted for the original spécification if it plays the part of component within a vaster system. This result supports a methodology of validation by integration

Повний текст джерелаSemi-formal and formal notations being complementary, their joint use could define an interesting framework in order to take advantage of their good points by reducing their drawbacks. On the one hand, semi-formal notations which are imprecise are good communication vectors with affordable training cost ; on the other hand, formal languages bring precision and their reasoning abilities which miss to semi-formal notations. In this work, we propose a translation approach from semi-formal object models to formal specifications in Z and Object-Z so as to offer a powerful integration of these two kinds of specifications. We want to make our proposals the most useful possible by showing three established advantages : a methodological guidance to express constraints annotating an object model ; an help to check the models and their constraints and informal reasoning about the semantics of simple models. We also have developed a tool, RoZ that supports our approach by making semi-formal and formal notations live together. Finally, we study another integration approach, the consistency checking by meta-modelling for which we propose consistency rules between the object model and Z. This work enables us to compare this approach with our translation strategy to understand their advantages and drawbacks

Повний текст джерелаOur study concentrates on the techniques which offer an automatic support for the adaptation and the revision of the dynamic models. The objective is to study how bond graphs can help to conceive innovating systems answering a set of specifications expressed in terms of temporal or frequential behavior. The main concern of an engineer confronted with a modelling problem is to make an abstraction of the system he needs to model. It is a difficult task to determine which aspects or properties are relevant for the system at hand. Sometimes these choices may be the source of models with inconsistencies that will fail in the analysis or control phase. Several physical aspects of the system (friction, fluid inertia, etc) that were not taken into consideration may be the cause of an inconsistent model. With our approach the intention was to point out another capability of this method, that of a reconstruction tool, which may indicate to a possible solution in case of an inconsistent with specifications design. We also wish that the system suggested in this study to be used as a tool in conceptual design of technological devices subjected to a set of specifications

Повний текст джерелаForesters need tools to map the tree species, tree heights, stand structure and biomass. Although the airborne lidar (Light detection and ranging) technology does not give access to all these variables, it can provide quick, accurate and spatially explicit measurements of tree heights and biomass over large surfaces. However, lidar systems currently used have not been specially designed to performed vegetation studies. The adjustment of the technical characteristics of such systems is expected to improve the accuracy of retrieved forest parameters. Consequently, the objective of this thesis is to determine configurations of lidar sensors dedicated to the study of forest vegetation, and to propose methods designed to extract forest parameters depending on the different configurations. The ability of different resolutions (footprint size and spatial sampling), wavelengths and sampling modes of the backscattered signal to measure forest parameters (canopy height and density, crown size and also volume and biomass) was evaluated. The studies were conducted from tree to stand level, on experimental or simulated data. In a first part, we developed methods to process classic airborne lidar data (scanner system, tens of centimeter footprint, 5 measurements/m², near-infrared laser) for the estimation of the biomass of individual trees. In this study, we demonstrated the contribution of new data called "Full-waveform" (recording the entire signal) compared to traditional multi-echoes data (extraction of the most significant echoes). In a second part, we performed an experiment using a Comissariat of Energy Atomique (CEA)'s lidar prototype onboard an ultra-light aircraft (profiler system, 2.4 m footprint, 2.4 m spacing between two measurements along the flight line, ultraviolet laser). Such a configuration did not allow to measure individual trees, but we were able to study variations in forest structure at the plot level (30 m diameter). Having demonstrated the ability of an ultraviolet lidar to perform vegetation studies, this sensor opens the way to the development of bi-functional lidar for both atmosphere and vegetation remote sensing. In a third part, large footprint lidar signals (tens of meters on the ground) were simulated from the aggregation of classical airborne lidar signals. We proposed a method for modeling the signal dynamics of satellite lidars in different forest types, in order to calibrate the energy to emit for a future space-borne mission. The main problem with large-footprint size is the strong influence of topography on accurate measurements of tree heights in steep areas. We consequently developed a method to correct this effect, thus increasing the accuracy of tree height retrieval. This approach also opened new perspectives in topography assessment from large-footprint data in forest environments

Повний текст джерелаThis thesis is divided in two parts. The first part suggests a theory of humour, it starts studying that concept by explaining its enunciative, logical or syntactical structures in order to draw a clear vision of it, before offering a first attempt to define it. Then it establishes necessary distinctions between the various categories of the risible to refine the delineation of the contours of humour. Once the concept is marked out, the theory of humour suggests an original typology of humourous themes and a study of the three main variations of humour, before focusing on its purpose. The second part discusses, in the light of certain concepts developed in the first part, the question of humour in science fiction literature. Because of the few previous studies on the matter, it opts for a broad perspective and deals with various aspects of the phenomenon. At first, thought dwells on the origins, themes and reading pact of science fiction to analyze their impact on humour. Then it analyzes the actual share of humour compared to the other categories of risible before studying its development and its influence in science fiction. The last development of the thesis examines and classifies the interaction between humour and science fiction from the least significant to the most typical. It reaches the conclusion of the existence of a science-fictional humour that leans upon the creative power of the genre. Finally, the study finds a distinction between the existence of humour in science fiction and humourous science fiction depending on the amount of humour in the texts. It then focuses on the humourous science fiction and identifies its structures by analyzing the prominent elements of the stories, before looking at the impact of this relational dynamics on the construction of the characters

Повний текст джерелаCurrent Systems Engineering framework must evolve in order to take into account the critical interactions of human-machine systems since the specification phase. The objective is to ensure that the behavior of such systems is kept within an accepted domain of performances whatever is the context of use. Those performances depend on the synergies of the different interactions that take place between technical and human systems when operating a common object. Human Factors Integration in Systems Engineering also known as Human Systems Integration implies to start working on the overall performance of all the interfaces of a human-machine system. These different interfaces exhibit emerging complex interactions. Some of them are inquired to ease the whole system performances and facilitate system resilience capabilities within disruptive unanticipated environment. Other ones are designed to finalize the system mission according to the purpose of its context of use. The paradigm we have explored in our work is based on the hypothesis of possible inter-operations between physiological and technical processes for human-machine interaction specification by coupling a System Modeling Framework with the Mathematical Theory of Integrative Physiology one. Our work focuses on the physical and physiological requirements specification (modeled with SysML) of a visual perceptive interaction for human to perceive right the meaning of symbolic properties technical objects afford when they are being maintained in variable contextualized situations. Our specification work results lead us to propose a Model-Based Support Systems Engineering organization

Повний текст джерелаFor designing complex and sociotechnical systems, business experts are responsible for writing the functional specifications because of their operational expert knowledge. However, these experts do not usually own the programming knowledge of those who design supervision systems. The task of the system design expert is then to define the functional specifications. S/he writes them in natural language, and then provides them to the designers of the supervision interface and the control-command code. The designers’ job is then to implement and integrate the specifications into the system. Errors from the specification interpretation come from the difference of technical knowledge between the various partners involved in the project. Moreover, depending on the complexity of the system, the definition of functional specifications can be tedious.We propose a design approach based on task modelling and End User Development in order to obtain functional specifications validated by the business experts (mechanical engineer for example).Model-driven engineering techniques are implemented to automatically generate the specification interface (that integrates Recorder, Generalizer, Replayer, and Corrector), the system supervision interface to be piloted and its control program.The technical feasibility of the proposed approach was demonstrated through a proof of concept. This proof of concept was evaluated to demonstrate the interest of the approach in the design of supervision systems

Повний текст джерелаWe develop two complementary aspects related to the security of mobile agent systems: the static and dynamic aspect. The first is related to the specification of security policies which treats the various security concerns in mobile agent systems and covers the various concepts related to the modeling of such systems. The dynamic aspect takes an interest to define a set of elementary operations which may change a given policy and a framework that expresses the adaptability of the agent policy to the security requirements of the new visited system. All Specifications are coded in Z notation.Another main contribution consists in providing a formal verification framework which gives more completeness and more consistency to the proposed specifications for both aspects. All checking processes are implemented under the Z/EVES theorem prover. Finally, we have take advantage from this theoretical work and we have defined an operational framework for enforcement security policies which combine the strengths of AOP with those of formal methods

Повний текст джерелаThe aim of this work is to improve the clarity and precision of the technical specifications written in French by the engineers at CNES (Centre National d’Études Spatiales / National Centre for Space Studies) prior to the realization of space systems. The importance of specifications (and particularly of the requirements that are part of them) for the success of large-scale projects is indeed widely acknowledged; similarly, the main risks associated with the use of natural language (ambiguity, vagueness, incompleteness) are relatively well identified.In this context, we would like to propose a solution that would be used by the engineers at CNES (who are currently not asked to follow specific writing rules): in that respect, we believe that this solution should be both effective (i.e. it should significantly limit the above-mentioned risks) and not too disruptive (which would make it counterproductive). A Controlled Natural Language (CNL) – i.e. a set of linguistic rules constraining the lexicon, the syntax and the semantics – seems to be an interesting option, provided that it remains close enough to natural language. Unfortunately, the CNLs for technical writing that we have examined are not always relevant from a linguistic point of view.Our methodology for developping a CNL for requirements writing in French at CNES relies on the hypothesis of the existence of a textual genre; besides, we make use of existing Natural Language Processing tools and methods to validate the relevance of the rules on a corpus of genuine requirements written for former projects

Повний текст джерелаThe main objective of this study consists to analyse empirically the behaviour of the short-run demand for money over the past twenty five years in some developing countries such as Ghana, Kenya, Tanzania and Zimbabwe with recents techniques for cointegration. The study started first of all, with a broad review of standard theories of the demand for money, particularly concerning the specification and the stability of the function. After, we tested the demand for money function by using a large number of econometric techniques, among which, the CUSUM test, the CUSUM squares test, the Chow test, the ARCH model and a variety of White test. According on those tests, we draw the conclusion that the demand for money functions presents a strong stability in Zimbabwe even the definition of money. In Ghana, only Ml presents some stability. However, in the case of Kenya and Tanzania, the short-run demand for money appears to be unstable even Ml or M2. Since the short-run stability of the demand for money allows to appraise the impact on the economy of a change in the stock money supply, it seems most appropriate and efficient to use the money stock as the key control instrument for achieving a stable economic environment

Повний текст джерелаThe design of control-command systems often suffers from problems of communication and interpretation of specifications between the various designers, frequently coming from a wide range of technical fields. In order to address the design of these systems, several methods have been proposed in the literature. Among them, the so-called mixed method (bottom-up/top-down), which sees the design realized in two steps. In the first step (bottom-up), a model of the system is defined from a set of standardized components. This model undergoes, in the second (top-down) step, several refinements and transformations to obtain more concrete models (codes, applications, etc.). To guarantee the quality of the systems designed according to this method, we propose two formal verification approaches,based on Model-Checking, in this thesis. The first approach concerns the verification of standardized components and allows the verification of a complete elementary control-command chain. The second one consists in verifying the model of architecture (P&ID) used for the generation of control programs.The latter is based on the definition of an architectural style in Alloy for the ANSI/ISA-5.1 standard. To support both approaches, two formal semi-automated verification flows based on Model-Driven Engineering have been proposed. This integration of formal methods in an industrial context is facilitated by the automatic generation of formal models from design models carried out by business designers. Our two approaches have been validated on a concrete industrial case of a fluid management system embedded in a ship
