PLM/PDM Flashcards
Mention three reasons for the increased industrial need for IT support for product development.
Shorter lead-times and product lifecycles
Increased complexity: variants, functions, components etc.
Collaborative product development
What is the aim of a PLM system?
PLM systems aim to support the creation and management of all information related to a product throughout its
lifecycle
Mention three things that a Product Data Management (PDM) database should provide.
A database “vault” for secure storage of information
Product structure management
Process management
PLM and PDM are two acronyms used in relation to the product realization process. What do they stand for?
Product Lifecycle Management and Product Data Management
Describe what PLM and PDM systems are and how they relate to each other.
A PDM system manages all information needed to manage the product definition during its lifecycle. It is not
only a database but also a toolbox for rationalizing engineering work.
A PLM system aims to support the creation and management of all information related to a product throughout
its lifecycle. That means that it includes a PDM system for data management bur also tools to create data, e.g. a
CAD, simulation software, etc.
How can PLM systems support an Engineering Change Management process?
Automation, e.g.:
- Workflow functions automate information transfer
- Standard templates for change documents
- Parameterized CAD/CAM/CAE models
Monitoring, e.g.:
- Follow-up of engineering changes status
- Overview of all engineering changes
Information access & retrieval, e.g.:
- All have access to engineering changes in PDM database
- All info and doc’s related to an engineering change is connected
Quality assurance, e.g.:
- Only authorized individuals may promote change requests
- Control of versions, status and effectivity
Review, e.g.:
- Check change history, rollback possible
Describe two different types of Bill of Material that are used in PLM systems.
. Describe two different types of Bill of Material that are used in PLM systems. (3p)
1. The engineering Bill of material (E-BOM)
Organizing the various components of a product including software
2. Manufacturing Bill of Material (M-BOM)
Structured according to the way a product is sourced and manufactured.
Primarily supports supply chain including manufacturing
Mention two important tasks for a PLM systems functions for version control.
Keep track of all versions of a specific piece of information
Pick up the currently valid version as well as at given earlier dates – the information’s history
