What is a Digital Twin?
A digital twin is the digitized image of physical assets such as a production machine. The individual tasks are digitally modeled, recorded, reproduced or simulated by software. Even the 1visualization of key figures, such as a temperature curve or the units produced, is sometimes referred to as a digital twin. Here, the overall picture is not yet displayed, but only individual data measured by the sensors. They form the “life data” of the digital twin.
There are different levels within the virtual image. The final level is a virtual 1-to-1 representation of the whole machine and simulates the individual processes. This, for example, makes it possible to apply a virtual load to a robot arm to check how the manipulator behaves under load. Physical simulations are another part of this: Especially in aircraft construction, flow simulations are carried out to analyze the behavior without having the aircraft physically available.
In this final level, there is also a link with the Enterprise Resource Planning System (ERP), that is, with the resource planning process of a company. Here, supplemental data of the suppliers and the various materials are collected. In aircraft construction, this is already considered standard today. Every single spare part is recorded; thus, the exact source is visible: Who purchased this part when and where, where is it in stock, what quality level does the spare part have and what were the purchasing costs?
Asset & Configuration Management
The Digital Twin creates a digital representation of all assets and staff within the production hierarchy and provides insight into all relevant data, processes and events.
- Key Figures & KPIs
- Historical machine data
- Machine malfunctions
- Live image & digital twin
- Production hierarchy as per ISA 95
- Intuitive user interface
- User-specific visualization
- Access via a web browser and mobile devices
Asset Task & Issue Tracking
The centralized task management for users and operators allows you to track overdue, open and completed tasks on the machine, employee and team level.
- Manual tasks
- Interval-based tasks
- Measured value/condition-based tasks
- Predictive tasks (Machine Learning)
- Display per machine, employee or team
- Standardized interfaces to existing IT systems
Asset Activity Stream
Each entity has its timeline to display all relevant human and machine activities along with posts, comments and likes. In this social network of man and machines, processes become easier to understand and to optimize.
- Separate timeline per entity
- Posts, comments and likes
- Human and machine activities
- Accumulation of searchable knowledge
How Companies Benefit from Digital Twins
Why should manufacturing companies invest in a digital twin in order to enter the IIoT quickly? From the beginning of the use of a digital twin, results can be achieved without a great deal of hardware effort, driving process optimization forward. Because in the initial step it is not yet necessary to link data together. After all, it’s all about getting to know your machinery better. By the end of the project, e.g. all machine KPIs are displayed, and all documentation and work instructions are recorded. This collected knowledge is pooled in the digital twin.
Extracting individual data and the process of creating a visual image improves the overall understanding of process operation. As a result, different products and processes within the organization benefit from sustainable improvement. Thanks to the machine data visualization, new fields of business can be explored which have a positive effect on business success.
The Bigger the Plant the Better
A digital twin is profitable when complex systems are involved. As a rule, the larger the lot produced, the more relevant a digital twin will become. This is especially true when all product and process performance indicators have not been recorded so far.
Besides, a digital twin improves efficiency, which plays a pivotal role in large production volumes. With the help of the digital twin and the data collected here, company staff can better understand their plant and machinery, develop more streamlined processes and identify problems earlier. This results in time savings and reduced material consumption in production.
Additional Optimization with Dataface
