Recently, advanced engineering modeling serves representation of emerging multidisciplinary cyber-physical (CPS) product systems. Multidisciplinary modeling requires functional-logical level while CPS demands system level product model. In functional-logical structure, behavior representation assures concept level virtual execution of the model. Product development purpose of model is extended to...
In this paper, novel method is introduced to establish content driving of engineering model entity definition and generation at computer description and representation of multidisciplinary industrial product system. Main objective of this work was developing new structure of driving content which made construction of requirements, functional, logical, and physical (RFLP) structured product model easier...
This paper is about extended application of virtual engineering principles, methodologies, and systems as a possible answer to urgent need for integrated industrial, research, and higher educational programs and processes. One of the motivations is the changed world of engineering which requires quick utilization of new findings as new context. At the same time, development of virtual engineering...
Development of modeling systems for product engineering or experimental purpose was enforced by need for engineering of cooperating systems operated multidisciplinary products during the recent years. As result the requirements, functional, logical, and physical (RFLP) structured model replaces the pure physical level representations in industrial engineering modeling systems at leading industries...
Representation of cooperating systems in recent products and collecting organized engineering knowledge in organizational intellectual property are currently actual issues on the long way of engineering model integration. Engineering model with those representations inherently includes components from various discipline areas in a single structure and recently uses requirements, functional, logical,...
This paper is about new methods which are contributions to system level interdisciplinary definition of multidisciplinary engineering structure (ES). Definition of ES is flexible. It may be product, functional unit, or experimental configuration of components. Developers of engineering modeling systems were forced to extend conventional physical level representations with system level representations...
One of the most dynamically developing applications of industrial electronics is active representation of product information in cyber-physical systems for high level engineering problem solving. Recently, modeling in industrial product lifecycle management (PLM) systems was extended to higher abstraction as the conventional physical level. Long way on development of integrated, active knowledge driven,...
Theoretical, methodological and systemic resources were developed on the way towards product system model centered and intellectual property driven engineering during the past decade. These developments enhanced communications between humans as well as between humans and physical objects. Leading industries utilized new generation of product lifecycle management (PLM) systems in connection with smart...
Organization of product information in requirements, functional, logical, and physical (RFLP) model structure is recent result on the long way from conventional documents to comprehensive and consistent virtual environments in engineering. Recent virtual engineering environments utilize generic product model which is self adaptive in order to assure its automatic instantiation in case of changed circumstances...
Product model based engineering long history of which started with computer aided design, manufacturing, and engineering (CAD/CAM/CAE) solutions recently utilizes product model which represents product as a system. In this new generation of product model, parts and units of product are modeled on the physical level as formerly. However, this level is supported by three higher abstraction levels of...
This paper introduces a new method as contribution to product definition on logical, functional, and requirements levels of abstraction in order to assure conceptual model of multidisciplinary product and achieve better physical level modeling. This method is result in a long term research program at the Laboratory of Intelligent Engineering Systems (LIES), Óbuda University. The main concept is establishing...
Product definition in virtual environment is done in the course of engineer and built in knowledge controlled generation of entities for lifecycle integrated model of product. Two recently emerged development directions in this area are company intelligent property (IP) controlled generic product model and unified abstraction based product concept model of multidisciplinary products. These two directions...
Integration of engineering activities from first idea to recycling of product yielded product lifecycle management (PLM) systems. Classical PLM system relies upon highly integrated physical level model of product. This integration does not support multidisciplinary product engineering because capability of classical PLM modeling can not provide the demanded unified modeling mechanism for different...
Challenges in product definition and application related engineering stimulate quick development of product lifecycle management (PLM) systems. The main directions of this development are adaptive definition of product, extending PLM model definitions to higher level of abstraction, and automation of the model generation by including model definition activities in product model. Joining to the above...
Automation of product definition in those Product Lifecycle Management (PLM) systems where lifecycle applicable product model is in the centre of engineering activities is important because reproduction of former models and propagation of change effects in the product model using conventional modeling methods are impossible. Automation requires representation of the relevant knowledge in the product...
Classical problem in engineering modeling is that product changes and environmental effects on product are hard to propagate in the product model during engineering activities for the lifecycle of products. In order to support change handling, product modeling in current product lifecycle management (PLM) system uses feature and contextual connection definitions to realize self-adaptive characteristics...
Current product definition in Product Lifecycle Management systems is done on the level of features. Feature modifies previous state of product model in a well defined way. Features defined on product are modified along contextual chains of feature parameters when situation or event change is recognized by experience and expertise based knowledge features. Features those drive event changes in product...
One of the actual problems in product lifecycle management (PLM) is consideration of requirements from various systems. While a PLM system is focused on object interactions within a product, engineering for a product system requires interaction with other systems. This experience motivates research in integration of System of Systems (SoS) and PLM methodologies. In order to do the next step to include...
This paper introduces selected latest results of a research in situation based product definition. The current representative method of product definition applies situation based control of product feature parameters. In the presented method, application of situation control was improved by placing it from the product feature level to the product behavior level. Because the feature level situation...
This paper introduces new objective related knowledge driven product feature definition method in order to achieve better human influence on feature definition in model based product engineering. The proposed method utilizes earlier relevant results by the authors in knowledge communication intensive product modeling and it is devoted as a contribution to solution for some actual problems in current...
