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,...
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,...
New comprehensively integrated, model and simulation based, and intellectual property driven way of product engineering which also serves fundamental, problem specific, and product specific research motivated a new concept called as multifunctional engineering space (MES). The MES concept was defined as new bridge which connects industrial product engineering processes, activities to reuse industrial...
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...
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...
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...
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...
As one of the most important achievements during the last decade in product lifecycle management (PLM), contextual object definition became main integrating factor in product models. In this paper, the authors introduce their recent results in contextual product modeling. Four aspects of contextual product object definition are discussed and recent related results are introduced. The aspects are contextual...
Product model enhances engineering work by the application of techniques such as modeling by features, contextual definition of engineering objects, application of active knowledge, and real time analysis of product modification consequence. These achievements are efficient in local product definition where small number of parts is considered. However, decision on a single product object in large...
