Abstract:

Intelligent object-oriented modelling is a technique for organizing heterogeneous knowledge in a uniform way. It is concerned with three aspects of engineering applications: the independence of modelling from simulation, object-oriented paradigm and knowledge-based systems. The thesis investigates these three aspects and addresses their practically usable concepts. A model of engineering modelling is decomposed into a trinity of descriptions: static, dynamic and functional, which are all needed for a complete model presentation. An object-oriented information model is designed using OMT for the purpose of model development along this line. A model development scheme is proposed to formalize the modelling process and a knowledge representation scheme is suggested to classify the modelling process. A co-operation scheme is presented as a unified approach of both these schemes. An application architecture with a multidisciplinary shell on top of an object-oriented kernel is proposed to combine knowledge-based modelling and object-oriented modelling with conventional tools. A prototype system has been implemented in Kappa. The prototype system structure has been considered in the context of both the modelling process and the knowledge functionality. The thesis concludes that intelligent technologies are natural tools for concurrent engineering applications and are not only suited to inductive approaches and qualitative representations but also to deductive methodologies and quantitative descriptions.

Abstract:

This thesis describes extensions to an object-oriented database, and the use and benefits of the resulting system in protein structure analysis and homology modelling. An object-oriented database based on a semantic data model (the functional data model) is used to store protein structure data. The logic programming language Prolog, together with the object-oriented database, is useful in protein structure analysis applications that require a combination of data retrieval and calculation. This is demonstrated by the implementation of a procedure for identifying clusters of interacting residues in hydrophobic protein cores. Knowledge of the three-dimensional structure of a protein is important to a full understanding of its function. Experimental determination of a protein's structure is a slow and difficult process, so there is a demand to be able to generate hypothetical computer models of proteins. Homology modelling is the process of constructing a model of a protein based on predicted similarity to a protein with a known structure. A homology modelling system is described in which the object-oriented database is used to manage working data generated during the modelling process. The organisation of this working data is described. Both the database system and the Daplex query language have been extended to support parameterised action methods. These are pieces of code, typically for generating a display or performing database updates, that are stored in the database with the data. Tasks performed in homology modelling are expressed as action methods, and can be invoked using Daplex. The utility of the homology modelling system is demonstrated by the construction of models of domains II and VI of the complement proteins Cls and Clr.

Full text

Abstract:

The aim of this thesis is twofold. The first and major one is to develop an objectoriented Kaplan turbine model to support control design for hydropower systems. The model is developed in the Modelica language and implemented in the Dymola simulation environment. Using the equation-based modelling formalism of Modelica, the model exploits water flow and pressure balance equations to capture the relationship between the hydraulic and mechanical energy. A particular feature of the model is a detailed description of how the water flow and turbine torque are affected by the wicket gate and turbine runner blade angles. The second aim of the thesis is to demonstrate how the Kaplan turbine model can be used to design hydropower control systems. To this end, a relatively complete hydropower system model is developed using the model components and several dam control strategies are evaluated. This study clearly demonstrates the utility of the model in the design of hydropower control systems.

Abstract:

In dieser Dissertation, schaue ich auf objekt-orientierte Metamodellierung und wie sie verwendet werden kann, um Computersprachen zu beschreiben. Dabei, fokussiere ich mich nicht nur auf die Beschreibung von Sprachen, sondern auch auf die Verwendung von Sprachbeschreibungen zur automatischen Erzeugung von Sprachwerkzeugen aus Sprachbeschreibungen. Ich nutze die Idee von Metasprachen und Metawerkzeugen. Metasprachen werden verwendet um bestimmte Sprachaspekte, wie Notationen und Semantiken, zu beschreiben, und Metawerkzeuge werden verwendet um Sprachwerkzeuge wie Editoren und Interpreter aus entsprechenden Beschreibungen zu erzeugen. Diese Kombination von Beschreibung und automatischer Entwicklung von Werkzeugen ist als Domänenspezifische Modellierung (DSM) bekannt. Ich verwende DSM basierend auf objekt-orientierter Metamodellierung zur Beschreibung der wichtigen Aspekte ausführbarer Computersprachen. Ich untersuche existierende Metasprachen und Metawerkzeuge für die Beschreibung von Sprachvorkommen, ihrer konkreten Repräsentation und Semantik. Weiter, entwickle ich eine neue Plattform zur Beschreibung von Sprachen basierend auf dem CMOF-Modell der OMG MOF 2.x Empfehlungen. Ich entwickle eine Metasprache und Metawerkzeug für textuelle Notationen. Schlussendlich, entwickle ich eine graphische Metasprache und Metawerkzeug zur Beschreibung von operationaler Semantik von Computersprachen. Um die Anwendbarkeit der vorgestellten Techniken zu prüfen, nehme ich SDL, die Specification and Description Language, als einen Archetypen für textuell notierte Sprachen mit ausführbaren Instanzen. Für diesen Archetyp zeige ich, dass die präsentierten Metasprachen und Metawerkzeuge es erlauben solche Computersprachen zu beschreiben und automatisch Werkzeuge für diese Sprachen zu erzeugen.
In this thesis, I look into object-oriented meta-modelling and how it can be used to describe computer languages. Thereby, I do not only focus on describing languages, but also on utilising the language descriptions to automatically create language tools from language descriptions. I use the notion of meta-languages and meta-tools. Meta-languages are used to describe certain language aspects, such as notation or semantics, and meta-tools are used to create language tools, such as editors or interpreters, from corresponding descriptions. This combination of describing and automated development of tools is known as domain specific modelling (DSM). I use DSM based on object-oriented meta-modelling to describe all important aspects of executable computer languages. I look into existing meta-languages and meta-tools for describing language utterances, their concrete representation, and semantics. Furthermore, I develop a new platform to define languages based on the CMOF-model of the OMG MOF 2.x recommendations. I develop a meta-language and meta-tool for textual language notations. Finally, I develop a new graphical meta-language and meta-tool for describing the operational semantics of computer languages. To prove the applicability of the presented techniques, I take SDL, the Specification and Description Language, as an archetype for textually notated languages with executable instances. For this archetype, I show that the presented meta-languages and meta-tools allow to describe such computer languages and allow to automatically create tools for those languages.

Abstract:

Throughout the world, there are many legacy systems that fulfil critical business functions but often require new functionality to comply with new business rules or require redeployment to another platform. Legacy systems vary tremendously in size, functionality, type (such as batch-oriented or real-time), programming language source code, and many other factors. Furthermore, many of these legacy systems have missing or obsolete documentation which makes it difficult for developers to re-develop the system to meet any new functionality. Moreover, the high cost of whole scale redevelopment and high switchover costs preclude any replacement systems for these legacy systems. Reengineering is often proposed as a solution to this dilemma of high re-development and switchover costs. However, reengineering a legacy system often entails restructuring and re-documenting a system. Once these restructuring and re-documentation processes have been completed, the developers are better able to redevelop the parts of the systems that are required to meet any new functionality. This thesis introduces a number of methods to restructure a procedurally-structured, batch-oriented COBOL system into an object-oriented, event-driven system through the use of an intermediate mathematical language, the Wide Spectrum Language (WSL), using system source code as the only documentation artefact. This restructuring process is accomplished through the application of several algorithms of object identification, independent task evaluation, and event identification that are provided in the thesis. Once these transformations are complete, method(s) are specified to extract a series of UML diagrams from this code in order to provide documentation of this system. This thesis outlines which of the UML diagrams, as specified in the UML Specifications version 1.5, can be extracted using the specified methods and under what conditions this extraction, using system source code only, can occur in a batch-oriented system. These UML diagrams are first expressed through a WSL-UML notation; a notation which follows the semantics and structure of UML Specifications version 1.5 in order to ensure compatibility with UML but is written as an extension of WSL in order to enable WSL to represent abstract modelling concepts and diagrams. This WSL-UML notation is then imported into a visual UML diagramming tool for the generation of UML diagrams to represent this system. The variety of legacy systems precludes any universal approach to reengineering. Even if a legacy system shares a common programming language, such as COBOL, the large number of COBOL constructs and the huge number of possible dialects prevents any universal translator of the original program code to another. It is hoped that by focusing on one particular type of legacy system with constraints, in this case a batch-oriented COBOL system with its source code its only surviving artefact, and by providing validated algorithms to restructure and re-document these legacy systems in the Unified Modelling Language, an industry system modelling standard, and by determining which of these Unified Modelling Language can be extracted practically from such a system, some of the parameters and uncertainties, such as program understanding of an undocumented system, in reengineering this type of system can be reduced.

Abstract:

Approved for public release; distribution is unlimited
The United States Marine Corps (USMC) will be fielding the SINCGARS frequency-hopping radio system during the next 5 years. There will be units within the Corps during the transition period in which both the conventional fixed-frequency radio and the SINCGARS radio will be employed in the same area at the same time. The Marine Corps Communications Architecture Analysis Model (MCCAAM) presented in this thesis will give Marine Corps decision makers, analysts, and communications officers the ability to quantify the effectiveness of alternative tactical radio system configurations within a given Marine Air-Ground Task Force (MAGTF) environment. Using a unique traffic workload paradigm to generate realistic message traffic, this object-oriented simulation model assesses the overall performance of a given architecture with a specified mix of fixed-frequency and frequency-hopping radios through a penalty accrual process or through aggregating traditional communications MOEs. USMC decision makers and communications officers can use the results of the system performance rankings and associated sensitivity trade-off analysis to determine where best to allocate the new frequency hopping radios, as they become available, in order to maximize the overall FM communications performance of a given MAGTF.

Abstract:

The need for a product model which can support the modelling requirements of a broad range of applications leads to the application of a feature-based model. An important requirement in feature-based design and manufacture is that a single feature representation should be capable of supporting a number of different applications. The capability of representing products composed of assemblies is seen to be necessary to serve the information needs of those applications. To achieve this aim it is an essential prerequisite to develop a formal structure for the representation of assembly information in a feature-based design system. This research addresses two basic questions related to the lack of a unified definition for features and the problem of representing assemblies in a feature-based representation. The intention is to extend the concept of designing with features by incorporating assembly information in addition to the geometrical and topological details of component parts. This allows models to be assembled using the assembly information within the feature definitions. Features in this research are defined as machined volumes which are represented in a hierarchical taxonomy. The taxonomy includes several types and profiles of features which cover a general range of machined parts. A hierarchical assembly structure is also defined in which features form basic entities in the assembly. Each feature includes information needed to establish assembly relationships among features in the form of mating relationships. An analysis of typical assemblies shows that assembly interfaces occur at the face level of the mating features and between features themselves. Three mating relationships between pairs of features have been defined (against, fits and align) and are represented in the form of expressions that can be used for evaluations. Various sub-types of these major mating relationships can be identified (e.g. tight fit, clearance fit, etc.) and represented through the use of qualifying attributes. Component Relation Graphs, Feature Relation Graphs and Face Mating Graphs have been developed to represent each level of interaction in an assembly, and assembly relationships are combined with knowledge on process planning into a Component Connectivity Graph. These graphs are used as the basis for deriving an integrated data structure which is used for defining classes for each level in the assembly hierarchy. The implementation of a prototype system has been facilitated by use of an object-oriented programming technique which provides a natural method of adding functionality to the geometric reasoning process of features and the complex relationships between the parts that make up the assembly. The feature-based model is embedded in an object-oriented solid modeller kernel, ACIS®. The research demonstrates the possibilities for a single feature representation to support multiple activities within a computer integrated manufacturing environment. Such a representation can form the basis of design improvement techniques and manufacturing planning as well as be a model to support the life cycle of the product.

Abstract:

Two of the main needs when developing an information system for an organization are that system analysts know and understand the application domain and that the system properly supports the business processes of the organization. Consequently, elicitation of system requirements from business process models has been acknowledged as a suitable activity to deal with that needs. In addition, system requirements must be linked to subsequent development stages. However, system analysts can face many challenges when performing these activities. They may have problems communicating with customer stakeholders and may need to analyse and operationalize the purpose of the information system. Furthermore, system analysts must bridge the gap between business and system domains for specification of system requirements, specify different types of system requirements and guarantee that their specification is precise, consistent and homogeneous. In relation to object-oriented conceptual modelling-based information system development, system analysts must also avoid potential problems that may arise when a conceptual schema is created from system requirements as part of their link with subsequent development stages. For example, a conceptual schema can be incomplete and/or inconsistent if it is not properly managed. As a solution, this thesis presents a methodological approach for business process-based requirements specification and object-oriented conceptual modelling of information systems. The approach consists of four stages: organizational modelling, purpose analysis, specification of system requirements and derivation of object-oriented diagrams. By following the design research methodology for performing research in information systems, the methodological approach has been designed on the basis of many existing ideas and principles in academia and industry and provides new principles, mechanisms and guidance to address the challenges presented above.

Abstract:

One of the most difficult problems in modern biochemistry is that of accurately predicting a protein's three dimensional structure from its sequence (the protein folding problem). This structure is essential for a proper understanding of how a protein functions. As experimental derivation of a protein's structure is far more time consuming than deriving a protein's sequence, prediction of structure from sequence is an important goal for many protein biochemists; several methods have been suggested for this. Given a protein of known structure of similar sequence to the protein you wish to model homology modelling is the method most likely to produce a fairly good model. In this work a tool was produced for examining the various stages of homology modelling and analysing how well various method for carrying out these stages perform. The tool produced consists of an object-oriented database of protein structures and testbed software written in a mixture of PROLOG and DAPLEX. Tests were carried out using this software to examine the predictivity of various guidelines suggested in the literature for the loop selection stage of cut and paste homology modelling. The results of these tests produced surprising new information on the relative importance of different factors which may be used to choose between candidate fragments for the variable regions of a protein being modelled. The results of the application of these automated modelling methods were then compared with a short series of modelling tests using human modellers in an attempt to measure how the usual modelling procedures using 'hand and eye' compare with automated measures. Finally the results of the tests carried out were used to guide the production of a model of a previously unmodelled serine proteinase.

L'élément technologique constitue le volume de contrôle sur lequel les bilans matière et énergie sont établis. Un port est défini comme l'abstraction du lieu sur un élément technilogique où la matière, l'énergie ou l'information entre ou sort. L'implémentation a été réalisée sur la base d'une conception et analyse orientées objet, notamment la méthode UML et le langage C++. PRPOLY a été validé par rapport à l'installation industrielle par comparaison entre les valeurs culculées et des données expérimentales relatives à des modes de fonctionnement statique et dynamique.

Abstract:

This thesis argues that the fit between the planning and control system and the manufacturing organisation is a crucial element of success. The design of appropriate control systems is, therefore, important. The different approaches to the design of manufacturing planning and control systems are investigated. It is concluded that there is no provision within these design methodologies to properly assess the impact of a proposed design on the manufacturing facility. Consequently, an understanding of how a new (or modified) planning and control system will perform in the context of the complete manufacturing system is unlikely to be gained until after the system has been implemented and is running. There are many modelling techniques available, however discrete-event simulation is unique in its ability to model the complex dynamics inherent in manufacturing systems, of which the planning and control system is an integral component. The existing application of simulation to manufacturing control system issues is limited: although operational issues are addressed, application to the more fundamental design of control systems is rarely, if at all, considered. The lack of a suitable simulation-based modelling tool does not help matters. The requirements of a simulation tool capable of modelling a host of different planning and control systems is presented. It is argued that only through the application of object-oriented principles can these extensive requirements be achieved. This thesis reports on the development of an extensible class library called WBS/Control, which is based on object-oriented principles and discrete-event simulation. The functionality, both current and future, offered by WBS/Control means that different planning and control systems can be modelled: not only the more standard implementations but also hybrid systems and new designs. The flexibility implicit in the development of WBS/Control supports its application to design and operational issues. WBS/Control wholly integrates with an existing manufacturing simulator to provide a more complete modelling environment.

Abstract:

Within this thesis work a strongly simplified yet complete, component-based numerical model for load analysis of a horizontal wind turbine is built up. The model is written in the open-source, object-orientated and equation-based modelling language Modelica and designed in a modular structure which allows integration in OneWind, a specialised Modelica library for components of wind power plants which is being built by Fraunhofer IWES. The model makes continuous use of three-dimensional mechanical elements of the Modelica Standard Library. It comprises all components of an onshore wind turbine including independent subcomponents such as rotor, drivetrain, generator, controls and tower, as well as different wind models. A main focus is put on energy conversion in the rotor. With the established model an analysis of expectable blade root forces in a 5MW turbine under extreme conditions is performed, which are modelled using two different certification load cases. Based on these results a rough preselection of an appropriate blade bearing is carried out.

Abstract:

A combination of environmental awareness, consumer demands and pressure from legislators has led automotive manufacturers to seek for more environmentally friendly alternatives while still meeting the quality, performance and price demands of their customers. This has led to many complex powertrain designs being developed in order to produce vehicles with reduced carbon emissions. In particular, within the last decade most of the major automotive manufactures have either developed or announced plans to develop one or more hybrid vehicle models. This means that to be competitive and o er the best HEV solutions to customers, manufacturers have to assess a multitude of complex design choices in the most e cient way possible. Even though the automotive industry is adept at dealing with the many complexities of modern vehicle development; the magnitude of design choices, the cross coupling of multiple domains, the evolving technologies and the relative lack of experience with respect to conventional vehicle development compounds the complexities within the HEV design space. In order to meet the needs of e cient and exible HEV powertrain modelling within this design space, a parallel is drawn with the development of complex software systems. This parallel is both from a programmatic viewpoint where object-oriented techniques can be used for physical model development with new equation oriented modelling environments, and from a systems methodology perspective where the development approach encourages incremental development in order to minimize risk. This Thesis proposes a modelling method that makes use of these new tools to apply OOM principles to the design and development of HEV powertrain models. Furthermore, it is argued that together with an appropriate systems engineering approach within which the model development activities will occur, the proposed method can provide a more exible and manageable manner of exploring the HEV design space.The exibility of the modelling method is shown by means of two separate case studies, where a hierarchical library of extendable and replaceable models is developed in order to model the di erent powertrains. Ultimately the proposed method leads to an intuitive manner of developing a complex system model through abstraction and incremental development of the abstracted subsystems. Having said this, the correct management of such an e ort within the automotive industry is key for ensuring the reusability of models through enforced procedures for structuring, maintaining, controlling, documenting and protecting the model development. Further, in order to integrate the new methodology into the existing systems and practices it is imperative to develop an e cient means of sharing information between all stakeholders involved. In this respect it is proposed that together with an overall systems modelling activity for tracking stakeholder involvement and providing a central point for sharing data, CAE methods can be employed in order to automate the integration of data.
