Virtual Engineering
What is the definition of Virtual Engineering?
Virtual Engineering is the early and continuous support (from process and infrastructure view) of the entire product lifecycle concerning the coordination, assessment and completion of the activities of all partners within immersive virtual environments.
Virtual Engineering
Definition of PLM
Product Lifecycle Management (PLM) refers to the product-specific and company-wide information management that can integrate data, processes, business systems and ultimately people in an extended enterprise. PLM software system solutions allow to manage this information throughout the entire lifecycle of a product efficiently and cost-effectively from the concept, design and manufacture through service and disposal.
Virtual Engineering
What are versions?
Versions are comparable work results or development stages of a task or a product that occur in succession. A newer version, emerges through changes or further development of the latter version and is usually an improvement.
Virtual Engineering
Versioning types
• Versioning in chronological order: Versions arise in chronological order and have exactly one successor (in the simplest case).
• Versioning at different levels: Small changes are recorder in "intermediate versions", while larger development phases are documented in major versions
• Versioning with "based on" sequence: Versions can build on one another in the sense of a "based on" relationship, even if they do not follow the time sequence (e.g. V5 based on V2, even though it follows V4)
Virtual Engineering
What is Knowledge-based Engineering?
Context of use:
Virtual Engineering
Generative design
Virtual Engineering
Convergent modelling
Virtual Engineering
Objective - Improving economic efficiency
• Benefits:
- Shortening Time-to-Market
- Quality improvement
- Process assurance
• Reasons:
- Parallelisation of individual processes through digital models
- Removal of defects
- Current consistent data
-Transparency between sales, development, production and suppliers
Virtual Engineering
Explain the main components of PLM system solutions briefly
• Customer Relationship Management: CRM systems take care of the management of all customer relationships, including address info, contact history, offers, etc.
• Product Data Management: Systems for managing and archiving recent product and workflow related data and information
• Enterprise Ressource Planning: Goal is to apply all existing resources in a company to the operational process in the most efficient way, minimizing inventory costs, lead times and maximizing capacity utilization
• Manufacturing Execution Systems: Computarized systems used in manufacturing to track and document the transformation of raw materials to finished goods
• Supply Chain Management: SCM Systems are responsible for the planning and management of all tasks in a supplier selection and procurement, physical flow, storing of raw materials and other logistic tasks.
Virtual Engineering
What does versioning mean?
Is the process of assigning either unique version names or unique version numbers to unique development stages
Virtual Engineering
Explain the difference between analytically and parametrically described geometric models
In analytically described geometric models, the definition of the elements refers to sizes directly related to a coordinate system, while in parametrically described models the definition refers to sizes (parameters) that embody a property of the element
Virtual Engineering
Explain the corporate use, issues and solutions of VE
• Corporate use:
• Current trends and issues
=> lead to increasing cost and time pressure
• Solutions of VE
