Coined by Michael Grieves, Digital Twin describes a digital replica of a physical system. In manufacturing, digital twin refers to a dynamic software model of a production process or product that uses real-time data to mirror its physical counterpart.
Research forecasts that the global digital twin market will be worth $110.1 billion by 2028, growing at a Compound Annual Growth Rate (CAGR) of 61.3% from 2023 to 2028. The goal of digital twin solutions is to use these virtual counterparts for a variety of purposes like simulation, analysis, and control.
The benefits of digital twin solutions in manufacturing are manifold. So, it’s unsurprising that it’s one of the most adopted technologies in the last decade. By simulating and monitoring systems, manufacturers are now able to access features that aren’t visible in the physical world.
Digital twins offer a real-time view of the production line. Whenever this is the case, factory management can make immediate adjustments and exert complete control over the whole process.
Digital Twins come with the benefit of predictive analytics. This helps manufacturers identify potential machine failures or maintenance needs before they disrupt production. For example, product teams can test various operational scenarios and identify possible disruptions before making a decision.
Simulations are one of the best ways to predict the most likely outcome of any given scenario. Forecasting the results of process changes enables better decision-making. It can also help avert potentially disastrous scenarios.
Enhanced efficiency and predictive maintenance help minimize downtime and resource waste. Whenever all this comes together, it can positively impact the bottom line.
Several manufacturers are already harnessing the power of digital twins. For instance, in the automotive production line, a digital twin can enhance every step of the production process. Furthermore, digital twin also plays a critical role in maintenance protocols. In the aerospace industry, digital twins are employed to simulate and test aircraft performance under various conditions.
Another intriguing example is the integration of a Business Process Management or BPM engine with digital twins. Developing a custom BPM engine as a digital twin helps streamline business processes in real-time, optimizing the production line flow.
Understanding potential weak points in the production line and areas that need optimization is important. To do this, manufacturers must conduct an in-depth production process review. In this scenario, it’s not enough to just look at the data. You must also engage the production managers, line workers, and other stakeholders to get an in-depth understanding. This approach will help prioritize areas where efficiency gains, cost savings, or quality improvements can be realized.
Get a holistic view of your operations by collecting factory and operations data from a variety of sources, such as sensors, machines, and software systems. It’s important to install sensors on critical equipment and machinery (if not already present) and integrate data collection modules with a BPM engine, Manufacturing Execution System (MES), and Enterprise Resource Planning (ERP) solution. Ensure that the data you capture is high fidelity, frequent, and accurate. The more granular the data, the better the insights one can derive from it.
Build a virtual representation that mirrors the physical production line. You can build this model using a variety of tools and software platforms. Still, choosing the right digital twin software platform is crucial. You should make a choice that is based on compatibility, scalability, and specific requirements. Once deployed, map out all production processes, machinery, and worker roles. Validate the digital model by cross-referencing it with physical processes to ensure accuracy.
The primary objective is to build a live, dynamic digital twin that evolves seamlessly with the production line. Leverage the Internet of Things (IoT) devices or protocols to establish communication between sensors and the digital twin platform. In this scenario, ensuring that data transmission is secure and latency is minimal is critical. Furthermore, organizations must make an effort to calibrate and validate the sensors regularly to ensure data accuracy and effectiveness of the Digital Twin.
Finally, improve production efficiency, quality, and cost-effectiveness by leveraging insights from the digital twin. Manufacturers can do this by running simulations on the digital twin to predict potential inefficiencies, bottlenecks, or failures.
Factories can also use the insights from the digital twin to develop strategies for line balancing, reducing downtime, and improving overall throughput. Manufacturers can refine the digital twin’s accuracy and subsequent strategies by continuously comparing simulated results with actual production outcomes. However, to get the most out of digital twins, management must encourage and nurture a culture of iterative learning, leveraging Digital Twin as a tool for continuous improvement.
Implementing a robust BPM engine with a digital twin application in manufacturing requires a systematic approach. You have to have a clear understanding of the objectives to effectively integrate technology and data.
Define, control, and enforce a process flow on the factory floor. Create a digital representation of objects, models, control, decision-making, and data collection. Develop products following a strict step order with control exemptions. Track models in relationship to the different objects involved and route the logic based on the business object state. You must always ensure observability over execution history and correlation.
A digital twin for any production line should be able to track material consumption, inventory movement through the production line, station state data collection, and accurately validate properties and data for processes. Execute API orchestration of processes when receiving material after the workflow is triggered.
Once factory teams properly execute the digital twin, production lines can become more agile, efficient, and responsive to the dynamic needs of modern manufacturing.
In conclusion, Digital Twin technology is a cornerstone in modern manufacturing, offering an unparalleled approach to enhancing production line control and assembly. By creating virtual representations of physical systems, manufacturers can monitor, analyze, and optimize their processes in real time, achieving increased efficiency, precision, and cost-effectiveness.
Adopting Digital Twins allows for proactive maintenance, intelligent decision-making, and a significant reduction in resource waste and downtime, positively impacting the bottom line.
