One available technology that can distinguish a company from others and bring about advantages is the Product Lifecycle Management (PLM). The Product lifecycle Management is the management of all product related information and processes. The PLM system through database technology and intranet or internet network manages the production process in all product-related information and processes. This article brings a case study of the ongoing implementation of the PLM system in a company that produces power transformers engineered to order. The process and the experience gained in the implementation of PLM software are presented.

The developed application enables project managers to estimate completion time for process of creation of CAD models. Application use real data retrieved from PLM system about previous projects so more accurate time could be make. The developed application was embrace by the project managers as the very valuable tool.

The proposed information model will be used as a basis for the development of a program system to support the process of creation of the computer model of a product. The developed program system will be able to relate the Feature Based Design (FBD) CAD model of the product with the knowledge used in its creation. The FBD model of the product and the captured design knowledge make an Extended CAD model (ECAD).

Whether designer creates a 3D computer representation of the product, technical drawings or a CNC code, CAD applications like CATIA or ProENGINEER are most likely to be used. Due to the fact that most CAD applications lend a limited support for the process of property management and the creation of technical drawings, there is a need for a tool to better support both processes. The APM (Application for Property Management) introduces an innovative and new approach based on the XML description of the model property and drawing information required for the creation and manipulation of CATIA Product and Part model properties and the automatic creation of the bill of material in technical drawing. Also, the APM connects a model and its drawing (creation and change of drawing head and drawing part list table) in such a way that data synchronization is available in both directions.

The presented research attempts to answer how the proposed traceability methodology and framework could help designers to improve communication, eventually create new channels of communication, and contribute to the creation of shared understanding in collaborative design processes. The discussion of these issues is based on a literature review, empirical research, observations of industrial practice, and feedback from initial implementation. The research is focused on information objects (IOs), archetypically represented in the engineering domain as technical documents that are often complex structures constituted of textual, numerical, and graphical fragments. The presented approach is based on an abstraction of IOs’ relationships organized around specific contexts that are defined by a subset of product development ontology. Each IO could be repeatedly represented in various contexts thatmay contain different subsets of objects and their relationships. Such a representation also acts as a container in which the ontology concept instances are associated with IOs being developed and traced during the design episode. The usage of the proposed traceability methodology is discussed with examples of implementation and possible utilization situations. The paper is focused on explaining how the developed functionalities could help to resolve manifestations of inadequate information flow, which cause communication barriers in engineering companies. In addition, the proposed traceability methodology offers the possibility to record the detailed history of actions and events associated with IOs in the usage process of the product life cycle management systems. Based on the research findings, this paper argues that such a network of the traceability links and relationships may be viewed as a novel design communication channel.

After research introduction, review and systematization of the IT systems interoperability evolution are provided. Accordingly to the different computer and informational scientists' and experts' research results, different interoperability approaches are presented: custom coding, single standard, data warehouses, single systems, integration, and semantic-based information interoperability. In order to achieve the research goal, product development ontology harmonization is recognised as a main prerequisite for successful implementation of the newest computer technology and tools. The short overview on ...

This paper presents a vision of next-generation engineering working environments for virtual enterprises. The concept of "Virtual product development environment" (VPDE) that is enabled by a new generation of Internet based services is discussed. In considering the VPDE, the following issues have been identified as crucial: (i) integration of different applications within the same organization; (ii) integration of organizations, applications and content between different organizations in the same virtual enterprise; (iii) integration of partners. The Web Service, the latest evolutionary step in distributed computing, has been proposed as the platform for realizing the VPDE infrastructure. Different possible roles of the Web Services technology in the ...

The calculation performed according to the standard enabled only stress control in particular frame points, whereas numerical calculation, using final elements method gives larger span of stress and deformation results in grapho-analitytical form. One of the essential goals in solving the task was the usability of computer approach analysis with method of final polynomials Pro/MECHANICA in finding the solution of cited type of problem and the deviation valorisation of solution obtained by computer and classical calculation method.
