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...
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...
In currently applied product definition, product lifecycle management (PLM) systems apply integrated object modeling for contextual development of products in model space. In order to elevate this object level of integration to the level of knowledge, a new product modeling method is proposed. On the knowledge level of modeling, human makes attempt for model change by launching product objects accompanied...
A main drawback for currently applied engineering modeling is that large models in the industry with so many unorganized inside and outside relations are hard to survey and understand by engineers at definition of new contributions. The authors developed a new concept and methodology to improve current product modeling by an extension to new content based model entities. Content is defined by human...
Two main recent achievements of the first decade in this new century in model space based during product definition are representation of corporate knowledge in product model and extended application of contextual feature principle. Contextual connections are applied to define corporate knowledge features as relationships amongst product object parameters. Current product models include comprehensive...
Problem solving in engineering is increasingly based on knowledge based methods. The need for reliable, proven, and accepted knowledge makes introduction of computational intelligence in product development slow and problematic. In order to achieve advances in this area, object model definition, object model compatible knowledge definition, application oriented knowledge verification, and computational...
One of the main recent achievements in engineering is description of complex products and their physical environment in a single object model. This model has capabilities to serve engineering from the first specification of a product to recycling. New research programs were needed in order to establish a new style of engineering where engineers communicate model creation and application procedures...
Engineering in product definition traditionally concentrates on building structures of parts and assemblies. Other objects such as analysis results, manufacturing methods, and equipment control programs are mapped to part and assembly definitions. This style of engineering has been realized in model and simulation based product development. Product data management systems as extensions to product...
In this paper a new tool is proposed as a possible aid to study differences and similarities between the human and the artificial neural network (NN) learning of some verbal and mathematical elementary abilities. For this purpose, simple NNs of the multi layer kind (MLNN) have been build. These MLNNs are able to recognize some graphemes and/or to make additions of integers up to 1000. An algorithm...
During the recent years, a great change in engineering was replacing the conventional CAD/CAM/CAE systems with highly integrated product lifecycle management (PLM) systems. Earlier concentrations on specific fields of engineering replaced by a product concentration where an integrated product model has capability to accommodate all information needed during the lifecycle of the product from the first...
During the past decade, engineering moved into virtual spaces in the leading industries and product model became a medium between communicating engineers. This change motivated the authors of this paper to make a development on currently prevailing product representations where human intent, engineering objective are not included in product models. Lack of this decision background information makes...
Poor communication between engineer and engineer controlled product model data generation procedure has become a critical concern in virtual space based product development. Engineer does not able to communicate elements of thinking process at decision making on engineering objects and their relationships simply because current product modeling is not suitable for this purpose. This classical style...
Lifecycle management of product information relies upon modeling and simulation of high number of highly interrelated engineering objects. Two primary actual problems in creation of large and very complex product models in the industry are handling of high number of relationships amongst engineering objects and tracking the consequences of a changed engineering object on other engineering objects...
