Asynchronous exchange of structure data in practice
In the context of a PDTnet Application Project the bidirectional exchange of assembly data between DaimlerChrysler, Keiper and Behr was introduced and further developed and piloted in concrete projects between the partners. This contribution summarizes the experiences gathered in the project starting with an overview of the realized exchange scenarios. Besides IT related issues, the PDM based exchange of assembly structure information requires also organizational as well as process related actions and a clear commitment for their implementation. With regard to the IT related aspects, this contribution clarifies the requirements for flexible and modular exchange solution as well as the requirements for the management of the assembly structures inside the PDM systems. Focus of this contribution is to contrast the new STEP optimized exchange process on the one hand side and the previous process for exchanging structure data on the other hand side. Based on the experiences made in the project, recommendations with respect to the transfer of the project results to different OEMs and suppliers constellations will be derived. This includes also those aspects which need to be addressed specific to a project and/or the involved systems. Finally the required actions are contrasted with the reachable economic benefits in form of time and cost reduction, process safeness and possible quality improvements. 
PDTnet for manufacturing systems development
There are many similarities between the development of a product and the related production plant in respect of creation and communication of digital models. Scania and ABB have been studied the demands for a smooth flow of information to support the development of manufacturing systems for body in white in co-operation with IVF in Gothenburg and KTH in Stockholm. As a result of this ABB and Tecnomatix has developed a STEP/PDTnet processor for eM-Planner. This is the first commercial software which has developed a AP214/PDTnet processor for communication of digital plant models. The functionalities of this processor and further concepts to support the integrated planning work flow between OEM´s and Suppliers will be demonstrated at the PDTnet Final event. The results of the first tryouts where very promising. This triggered the start up of an interest group for Digital Plant within ProSTEP association. During 2003 a white paper for Body in White factories will be produced. A number of leading companies are now active in this work. One of the goals is also to be able to co-operate with similar activities in USA and Japan within the framework of SASIG-Strategic Automotive Product Data Standards Industry Group. The result will hopefully be globally accepted standards for the product data with its relations to manufacturing as well as the interfaces between systems which are used for manufacturing system development

Synchronization of automobile projects between OEM and supplier
Modern development processes within the automotive industry require a closer cooperation of car manufacturers and suppliers. In the early phase of product development suppliers are assigned with the construction of CAD models and PDM structures of modules and assemblies. To identify collisions between different modules resp. assemblies at an early stage, DMU (Digital Mockup) tests are made. In order to achieve a signification as high as possible from these tests and to work cost-optimizing (economization of Rapid Prototyping parts as well as other prototype parts), the manufacturers are interested to get highly up-to-date development data from their suppliers. Suppliers, on their part, require access on up-to-date data from their contractor, e.g. design space, connecting parts, etc. In everyday practice, relatively laborious synchronization processes are in the way of the mutual interest to have up-to-date data sets. The synchronization of automobile projects has been tested theoretically as well as practically within the application project Volkswagen-Rücker using PDTnet technology. A fully automated synchronization system has been developed. It allows to keep a defined data volume (PDM structure data as well as CAD models) synchronous between car manufacturer and supplier.
Process integration via online coupling of distributed product data
Today product data are continuously exchanged in a highly asynchroneous way be-tween BOSCH and BMW while working together as partners in a car development project. In the future product data shall be linked online in order to achieve a faster exchange of information.
The vision is: „Less classical data exchange, more sharing of common product data“.
The scenario „web integration“ explored the parallel online access of the own PDM-System and the systems of the partners by means of a neutral webclient. The neu-tral webclient facilitates the generation of a transparent and common view of the joint-ly developed product „on demand“.
Within the scenario „web integration“ BMW and BOSCH together have implemented and tested the following use cases:
Online access on configured product structure via EDM and BoM data
In the context of the PDTnet-Project an Application Project between
DaimlerChrysler CVG (Commercial Vehicle Group) and Delphi has been set up.
It’s objective is to evaluate methods and technologies which enable the user to work with data at its „place of origination“, without having the necessity of a preceding replication - the evolution from Data Exchange to Data Sharing.
The ongoing realization, embedded in the PDTnet Application Scenario „PDM Web Integration“ is technologically based on the Neutral WebClient in connection with the PDTnet-Schema (= STEP AP214 CC08 XML-Representation).
The most appearing characteristic of this Application Project is the combination of a standard PDM-Implementation (Delphi iMAN) with a substantially heterogeneous EDM/PDM system landscape (DC-Smaragd und -EDS/BCS).
The project’s data-scope is characterized by a way of acting on Delphi-side as a module-supplier for DC, where e.g. a door module for the truck - model range ‚Actros‘ has to be developed.
Collaborative Engineering using an e-Engineering platform based on open source technologies
Two worlds grow together - PDM/CAD integration in the automotive industry
Introducing SAP/PLM the Nothelfer GmbH decided to implement a direct integration between SAP/PLM and CATIA using the PROSTEP product. The presentation will discuss requirements for such an integration and alternate approaches in an automotive industry context. Advantages of a direct SAP-CATIA integration including STEP AP214 based exchange of product structure data will be introduced using the Nothelfer example.
Integrated Virtual Engineering
The traditional Vehicle Development Process is a sequence starting with a geometrical package integration integrated with styling, followed by design, development supported by simulation and finalized with Manufacturing Engineering and other downstream partners. A big challenge for the automotive industry is the reduction in development time to answer the change in customer’s growing flexible lifestyle. With the increase of CAX tools engineering partner’s development tasks become more and more parallel. First time cuts are possible. Next step of time reduction is the elimination of hardware stages and learning cycles based on capable virtual development. The natural drivers of development evolution, the hardware stages are past. A new process with efficient tools must be defined to steer Virtual Engineering. Virtual gates (Virtual Vehicle Assessments) are introduced to support the key engineering milestones. Measurable development tasks (deliverables) across all virtual partners are defined as well as the required stage dependent data content and maturity. Product innovations, development directions and data are synchronized regularly over the Vehicle Development Process. These key elements of Virtual Engineering are scalable for adjustment to further change in vehicle development timing. High level of development efficiency, transparency and collaboration is achieved.
Cross Enterprise Engineering: The future of PLM
Shorter lifecycles, increasing demands surrounding product liability, the requirements resulting from DIN/ISO 4001 and globalization, including international cooperation between suppliers and their customers, have created a need for parallel and coordinated cooperation between departments and companies within the supplier network or the customer/supplier relationship. These factors result in completely new and changing methods for the Development Management. Cross Enterprise Engineering is the successor to Simultaneous Engineering and Concurrent Design. It support all engineering activities throughout the entire product lifecycle from the early phases of recording requirements through product operation and end-of-life. Additionally, Cross Enterprise Engineering integrates customers and suppliers in this process. Cross-Enterprise Engineering combines PLM (Product Lifecycle Management) with CRM (Customer Relationship Management), SCM (Supply Chain Management), MRP (Material Resource Planning) and CFA (Corporate Finance and Asset Management) to form the strategic backbone of a company.
Managing successful Engineering Projects
Today the product development of the suppliers must steer a multiplicity of parallel running engineering projects, which require a location-spreading co-operation with internal and external partners (Collaborative engineering). In this distributed engineering network only those companies remain competitive, that optimally align processes, project organization and IT tools. For this reason Intier Automotives Interiors (IAI) and Magna Engineering Center (MEC) started a project for the harmonization of the project management within engineering together with CSC. The goal is to plan and steer development projects European-wide and location independent, according to standardized proceedings and processes. Since the success of such projects also depends on the involved people, in the future personal, social and methodical requirements will become important for project managers. Within the method, these requirements are covered by a role model. The role model outlines the project organization and describes the most important roles and responsibilities. Further elements of the method form the cross section processes for e.g. controlling, reporting and risk management apart from the processes for planning, initialization and controlling of projects. The difference to well-known concepts is that the several components of project work were not regarded separately. By the integration of single topics it was possible to align the engineering processes, the PM processes, the project organization, the role descriptions and tools. With the realization, which is i.e. made by method and team trainings, IAI and MEC meet the requirements to be a qualified project partner and system supplier in an international and distributed surrounding field.
Product Development for rubber composition and development
Freudenberg and SAP are sharing their vision and experiences using next generation planning tools in engineering and product development. Along the product development process for rubber compositions at Freudenberg it is shown how an integrated solution for quality planning is implemented. Advanced Product Quality Planning (APQP) is a method to handle all the activities connected with planning, monitoring, and documenting product development. This method improves the development process by emphasizing careful planning and defects prevention at a very early stage of a project in order to stop the costs of nonconforming products from piling up.
ABB benefits from cross-enterprise Engineering Collaboration
Driven by the requirements of their geographically dispersed organization, development teams and external engineering partners, ABB was among the first global players to implement collaborative engineering tools. The ABB Corporate Research organization launched the “Virtual Design Office” project in 1999. The VDO objective is to provide an environment for stakeholders in the design and supply chain that enables them to interact in the engineering process. The need for enterprise-wide deployment of the collaboration environment has created a new solution scenario, with the integration of CoCreate OneSpace and SAP PLM being a key element. This solution enables collaboration on common content while linking synchronous and asynchronous work methods into the SAP data backbone. A resounding interest in the solution is being shown from organizations that believe in the value of a global collaborative engineering culture. This presentation reveals ABB’s experiences while developing and rolling out the solution to its global engineering community, and will highlight the value and challenges of this endeavor.
Integrated digital process planning between OEM and suppliers at Audi Neckarsum
At Audi AG in Neckarsulm the planning of a body-in-white project is performed with the help of digital methods and tools. Within the detailed planning process design houses and suppliers are intensively integrated. The use of a digital systems environment enables synchronizing of planning processes between OEM and suppliers and a much better communication of the planning results. The exchange of planning data and the corresponding simulation models leads to a complete trace ability of the planning status and provides an excellent basis for decisions on planning alternatives. The system environment for the OEM - supplier integration was based on eM-Power-products of Tecnomatix. Tecnomatix supported the introduction and the support of integrated planning processes at the automotive OEM and the suppliers. Additional areas such as management of planning alternatives and support of engineering change management allow keeping complex planning processes secure, transparent and manageable.
Virtual Factory - How to solve the conflict between system diversity and supplier integration?
Virtual factory plays an important role in the transformation of traditional development processes into virtual development processes. In this presentation the main virtual factory application areas within the Adam Opel AG are layed out and it is clarified, that by a clear system strategy the number of systems can be reduced to a manageable measure, so that all conditions for a system integration are given. This is further supported by initiatives bringing humans, processes and technologies together. The external suppliers are playing a central role in this effort, since they are creating approx. 80% of the data within the virtual factory scope. A cross-functional team within Opel is developing the suppliers by different means to enable them to make efficient use of Opel systems and integrate easily into the Opel system and process world to create a long-term development partnership.
Collaboration across company boundaries: Problems and solutions within an automotive supplier
Processes are typically organized inside the company. A direct integration of partners in own processes can’t take place because of missing technology. The eLINK-technology, developed by CONTACT, makes it possible for partners in the automotive industry to define and develop workflows together, for example to establish a change-management across company boundaries. In addition, a common CAD data management is made possible by a PDM-Client. The application possibilities of this technology in the development process of the automotive industry are represented by example of a typical automobile supplier .
Holistic approach for formal and informal Engineering Change Management Processes
Change management (ECM) remains one of the largest challenges for the product life cycle. The costs and the delays caused by changes have a decisive impact on the profits of each specific product. It is also worth noting that change is not necessarily negative. Recommendations for changes often result from the product life cycle, and they can potentially result in sizable cost reductions. It is important to handle these changes as efficiently as possible among all the organizational units involved both inside and outside the company. The opportunities here can be found in the standardization and automation of formal processes above and beyond the corporate boundaries. These include the change requests (ECR), the change organization (ECO), and the change notices (ECN). On the other hand, there is a considerable potential for improvement in the informal processes, in other words, the processes that cannot be automated using workflows. Before change requests (ECR) can be placed formally, for example, alternate concepts have to be developed and then discussed and evaluated by all the participants. Central project areas, where the alternate concepts and all the related documents can be stored without redundancy, create a uniform view of the data and help to avoid discussions based on different versions of the latest data. On the basis of the shared data pool, numerous discussions and meetings generally have to be conducted so as to arrive at a change recommendation that is both economically sensible and realizable. Conferencing solutions here provide the opportunity for supporting short-notice discussions and meetings among distributed project teams without making it necessary to plan for long travel times.
Global Engineering Data Management & Collaboration to boost Profit
After more than a decade of MRP and ERP solutions, most electronics OEMs still suffer from fundamental weakness in their design-to-manufacturing workflow. These PLM Systems facilitate product innovation and evolution, directly impacting operating cost, time to market and time to volume. This unified system finally bridges the long-standing information gap between engineering and operations. On top it supports collaboration throughout the extended enterprise. Today, using advanced Zuken's CAD Tools and ePLM System, companies can rapidly create and modify complex products. As today, the production bill of materials (BOM) does not contain the same information as the design (EDA tool) database. Components account for 70% to 80% of the costs of most electronic products and more than 90% of line stoppages are due to component outages. Clearly, the development of a consistent set of data to manage the components selected for the design of a product and those on which the purchasing/manufacturing BOM are based is a desirable goal. In fact, bridging the component data gap can be a matter of survival for companies in today's economic downturn, or a major source of competitive advantage for those that manage to meet the challenge.The apparently simple change to the design-to-manufacturing workflow is, in fact, potentially a very complex project, particularly where OEMs have multiple sites across the globe and perhaps tens or hundreds of individual component databases. However, achieving a consistent set of component data, not just in design but throughout the manufacturing process, delivers a host of tangible benefits, all of which result in increased profit for the OEMs concerned. A sample of such processes including ROI calculation will be part of the presentation
Mobile Computing within Field Service exemplified by a PLM Backend Integration
Correct data provided in time at the right place are a prerequisite for correct decisions. When combined with wireless communication and a central repository of data, mobile computers like pen tablets or HMD devices support interactive work processes within development, production and service in an efficent way. By visual interaction of images taken from real objects with virtual objects generated by computers, augmented reality techniques allow to enhance actions in a real work environment on user‘s choice by additional knowledge coming from a remote expert. Looking at diagnostics and maintenance services in large systems and plants, the presentation explains today’s requirements, concepts and approaches for solutions using mobile computing in field services, those interconnected with established IT systems such as product data management and legacy systems. Additional information is presented on areas like: navigation within the complex plant building and its surroundings, provision of data needed on site like documents, drawings, manuals, descriptions of interferences and trouble shooting. The presentation substantiates furthermore today’s technical aspects of mobile computing in field service, like hardware, wireless LAN and so on, and also topics coming from practical usage like system landscapes and scenarios. Finally the achievable improvements by mobile computing in field service within business processes of a product lifecycle are addressed.
Collaborative Engineering - The key for an efficient design and development process Solution
Ability to innovation, flexibility and the potential, to react rapidly to individual requests of the market, are criteria for competitiveness of an enterprise in the global competition today. This in connection with the necessity to consistent cost control and strict quality management secures the position of the enterprise in the market. These basic principles of successful entrepreneurial activities require strongly the smooth cooperation of all involved groups. This is valid especially at the product design because the majority of the product data as well as of the later costs for the product itself as well as its production are determined during the development phase. But, the demand for cooperaation is not only related to internal structures, it is more and more important for the cooperation with external subcontractors as well as development and system partners. Processes and products can be improved qualitatively; product lifecycles, development and production times can be reduced significantly as well as the abilities of an enterprise network to innovate and react can be increased. In this way, Collaboration becomes the key for an efficient development process. Focus of an actual customer projet is the integration of CoCreate’s collaboration suite OneSpace into the cFolders-platform of SAP. During the first phase, we define together the relevant processes in the development network and prioritize the requirements for the integration solution. The actual state of this solution is shown in the exhibitation.

Electrical PLM: An Implementation of AP212 at General Motors
IVED (‘Integrated Vehicle Electrical Design’) comprises both a system and process for electrical design at GM. The current system uses Sherpa to manage the documents generated by the electrical engineering applications such as MentorGraphics. This contribution introduces the current IVED system and processes at GM, and gives an overview about the future PLM direction of IVED. The implementation of the new IVED PLM goes beyond pure document management and covers the management of detailed electrical objects, as they appear e.g. on swchamatic diagrams, and their relationships including connectivity. It is based on the GM’s conceptual Electrical Engineering Information Model (EEIM) which captures both functional and physical structures of harness design as well as configuration information to specify e.g. inclusion of specific wires based on option codes. The EEIM is based on AP212 and the so-called KBL information model specifically developed by the KBL working group of the ProSTEP iViP association to support wire harness design The Electrical PLM integration strategy and architecture centered around Teamcenter Engineering (iMAN) as the new PLM tool for the Electrical Design group will also be presented.
Enhancing Interoperability and Enterprise Co-operation by the Application of STEP-based Healing and Visualization Algorithms
The application of the product data model STEP can impressively enhance the interoperability of CAD-data from various CAD-systems and simplify enterprise co-operation. STEP enables the continous data flow throughout the product life cycle from design to downstream as well as for archiving purposes, as it offers a binding data model. STEP-based applications support the deployment of one digital master model, proprietary formats become superflous, inconcistencies and redundancies are avoided. The usage of STEP-data is supported by the completely STEP-based software system phenomic by avanion which offers specialized modules for enineering and cooperation tasks. Engineers can build up a STEP-based digital mock-ups generated by various CAD-systems like CATIA® or Pro/Engineer. The data quality of the CAD data can be checked and healing algorithms are provided by the software system phenomic by avanion. This guarantees a high data quality for further process steps. Geometry generated by the wiring system Catia® E3D can be transformed in order to be processed in CAD-systems. Downstream processes as well as high quality visualization of product data is supported by new shading algorithms. The original CAD-data can now easily processed also by non-CAD users. |
