Terminology: PDM cpdm PAM Document Electronic Technology PDM Product Lifecycle PLM EDM Collaborative Information Data Engineering PDT TIM TDM Management Asset Technical Almost any combination of terms is used, PDM (Product Data Management) and PLM (Product Life-cycle Management) seem to be most common PIM Enterprise Definition File: PDM_060919 Slide 6
Definition: Product Result of industrial activity Product family, brand, model, type, product class, configurable product Product configuration, fixed product Product individual general concept abstract class (cannot be manufactured) concrete class (can be manufactured) physical artifact, service activity File: PDM_060919 Slide 7
Definition: Product Data (CIMdata) All product related information Paper documents Digital files: Document files: specifications, configurations, purchase orders CAD drawings, models, assemblies, parts lists CAE analysis, NC programs and plans Information stored in data bases PDM manages three different product data life-cycles Product type life-cycle: product development approval and change processes beginning and end of production Product individual life-cycle: engineering production, maintenance, recycling Product process life-cycle File: PDM_060919 Slide 8
Definition: PDM ISO 13584-10 Parts Library: A representation of facts, concepts, or instructions about one or more products in a formal manner suitable for communication, interpretation, or processing by human beings or by automatic means. Crnkovic, Asklund, Persson Dahlqvist (2003): PDM is the discipline of controlling the evolution of a product and providing other procedures and tools with the accurate product information at the right time in the right format during the entire Product Life Cycle PDT (Product Data Technology)-advisory group: Product Data Technology includes all aspects of the definition and methods of processing information pertinent to product throughout its development and operational lifecycle. File: PDM_060919 Slide 9
Definition: PLM (CIMdata) What is Product Lifecycle Management (PLM)? A strategic business approach that applies a consistent set of business solutions in support of the collaborative creation, management, dissemination, and use of product definition information across the extended enterprise from concept to end of life integrating people, processes, and information File: PDM_060919 Slide 10
PDM system status today PDM systems coverage is more restricted: Current PDM systems do not include commercial data (stocks, purchase orders, invoices, cost accounting, etc.) of the company. They are managed by Enterprise Resource Planning (ERP) systems. Main interest of PDM lays on product support processes (R&D, etc.) Many PDM systems do not support configurable products and product individual and production process life-cycles PDM system does not create new product data File: PDM_060919 Slide 11
PDM motivation: Changing business environment Increased competition Global markets, aggressive market behaviour Shrinking budgets, lower production costs Products are becoming more complex, exploiting more technologies and built in vast number of variants Quality requirements (ISO 9000 etc) and customer responsiveness are increasing Global manufacturing (expanded teaming) Government and industry standards Less time and money for hassling Requirement for more efficient R&D: Concurrent Engineering File: PDM_060919 Slide 12

PDM items Item definition Items from the PDM point of view are those product related business objects which are frequently referred in product related processes, e.g. products, materials, documents, resources, activities. Use of standard items makes management and business transactions easier PDM corner stones Item categories Physical items systems, assemblies, parts, components, accessories Document items Product models and software Service items File: PDM_060919 Slide 22
Item views Life-cycle view Item revisions Classification (type) view Classification according to product properties Classification hierarchy Status view Item approval level Item efficiency Language view Structure view Structures dependent on processes Sales (offer, sales order) structure Design structure Manufacturing structure Delivery structure Installation structure Maintenance structure Physical product structure Functional structure Spatial structure File: PDM_060919 Slide 23
Item classification Required to search and browse items efficiently Standards: ISO 13584 Part Libraries, IEC 61360 electric components classification scheme standard Examples: Specifying code Parametric class hierarchy A Basic mechanical materials and components A2 Non-ferrous metals A20 Sheets and strips Fasteners (Length, diameter) A202 Coated sheets and strips Screws (Length, diameter, thread length) Cross head screws (Length, diameter, thread length, head diameter, standard) File: PDM_060919 Slide 24
Basic item data Identification Generally approx. 8 character code Classifying v. non-classifying Local v. enterprize wide Description Generally approx. 40 characters of cler text Classification Helps to find items Revising Revising method Revision identification Status (recommendation class) Manufacturers, vendors Other data Big systems: approx. 300 fields/item Item is specified to the level that is required by its user Reference documents File: PDM_060919 Slide 25
Item revisions Warning: there is no approved terminology When an item is changed a new version, which is also an item, is created. It is Revision. An item of this type is generated to replace its predecessor immediately or after a transition period. Therefore, the new revision must be compatible (form, fit and function) with its predecessor. Variant. Variant concept is sometimes used for products, parts and items with small differences. An item in this group is related to a higher-level product type. Independent item. An item in this group is neither a variant nor a revision of any other item. The relation to its origin is lost. Example: a new independent product File: PDM_060919 Slide 26
Document management Which document types? Identification method for documents, document revisions and variants Approval of documents Security archives Document tool integration to PDM WWW user interfaces Document structure Document revisions Document variants Equivalence of documents written in different languages Multilingual documents Subdocuments Multipage drawings Figure files 3D models Representations Original,, viewing and printing formats File: PDM_060919 Slide 27

Product (breakdown) structure - general All structure items represent elements which can be delivered with the product. They are often physically attached to it. Product requisites like coatings, paints, welding wires, packages, adhesives, lubricants, chemicals are often left out of product structures. All items are identified with a code. A clear text description is required as support information. Physical products include only physical objects as components: non-decomposable (atomic) component, e.g. bolt, integrated circuit, cardboard package box, user manual multipart component File: PDM_060919 Slide 29 subassembly, e.g. phone receiver kit (group, no assembly process), e.g. installation accessories other material, e.g. 50 m rope, 3 l oil most common views: product (design/manufacturing), location
Documents and product structures Documents are linked to products: Product - parts list, assembly drawing Often this link is built into the identification system Product - other manufacturing documents Assembly instructions Test instructions Product specifications etc. Product - deliverable documents deliverable documents are items in product structure File: PDM_060919 Slide 30
References In addition to document links other type of items can be attached to product structures Product - jigs, fixtures Product - tools Product - embedded software Product - NC software File: PDM_060919 Slide 31
