Well, we've got some great things coming along on the show in just a few minutes, and today we're going to talk about digital twins in the supply chain. What are they, why do we need them, how do they work, when do we apply them? And we're going to look at the pros and cons of using digital twins. When we think about transforming supply chains, digital twins can play a big part. But, of course, we first of all need to know what we mean by the term digital twins. Why are they used, when are they used, how are they used and where are they used? In today's interconnected world, supply chains are becoming increasingly complex and businesses are constantly seeking ways to optimize operations, improving efficiency and reduce risks. Enter digital twins, a groundbreaking technology that's reshaping supply chain management. We'll explore here digital twins through five key questions what are they, why are they necessary, when do we use them, how do we use them and exactly where do we use them? So let's just first of all briefly answer those questions before diving in to some further examples.

Tony Hines: 1:47

A digital twin is a virtual replica of a physical supply chain. It's designed to simulate, monitor and optimise real-world operations. By incorporating real-time data from sensors, internet of Things devices and advanced algorithms, digital twins offer an interactive, dynamic model of supply chain networks. This allows businesses to gain insights into performance, predict outcomes and implement solutions without disrupting any physical operations. Why are digital twins important? The benefits of digital twins in supply chains are substantial, enabling businesses to enhance operational efficiency. By analysing bottlenecks and inefficiencies, companies can streamline their processes. We can reduce costs. Digital twins can optimise logistics from delivery routes to to warehouse layouts, cutting unnecessary expense. We can mitigate risk by simulating what would happen if, and we help predict disruptions like delays or shortages, and prepare contingency plans. So we can plan our resilient supply chains in this way, through simulation using the digital twin, and we can boost visibility. With a digital twin, businesses have a real-time view of their supply chain, ensuring better decision making. If you want to make better decisions, digital twins are a way to go.

In an era where adaptability is key, digital twins are becoming indispensable tools for staying ahead of the competition. So when should you use and adopt a digital twin. Well, adopting digital twins depends on a company's specific needs and readiness, and here are some indicators. When supply chains are facing increased complexity due to globalizationisation or evolving customer demand, then digital twins would seem appropriate. When unexpected disruptions such as pandemics or natural disasters highlight vulnerabilities in the existing supply chain, a digital twin could confirm or reject the notion that you have vulnerabilities. You can see where they are. You can test out where those vulnerabilities might arise, how they might play out in reality, and then you can take steps to actually close the vulnerability, get rid of it, have a strategy ready. It's preparedness. When a company has access to the necessary infrastructure, including internet of things devices, cloud computing and AI-powered analytics, then you're probably ready. The earlier, of course, the businesses are able to adopt digital twin technology, the better equipped they are to handle both current challenges and future uncertainties.

Tony Hines: 4:45

So how do these digital twins actually work in practice? Digital twins operate by integrating advanced technologies, and we've mentioned them. The Internet of Things sensors that collect real-time data on inventory levels, transportation conditions and production processes are examples. Transportation conditions and production processes are examples. Artificial intelligence and machine learning can also be part of the digital twin simulation by analysing data to create simulations and predict outcomes. And cloud computing, of course, enables storage, processing and accessibility of large amounts of data across the global supply chain, which is accessible anywhere. For example, a retailer might use a digital twin to optimize inventory levels by simulating consumer demand patterns. Similarly, a logistics company could predict and avoid potential delays by analyzing weather conditions and traffic data.

Tony Hines: 5:40

So where are digital twins actually being used? Let's get some good examples. The versatility of digital twins means they are being embraced across many industries. Retailing, for example Companies such as Amazon use digital twins to enhance inventory management and streamline warehouse operations. In the automotive industries, digital twins help manufacturers coordinate the delivery of parts to assembly lines, reducing downtime. In the food and beverage businesses, they utilize digital twins to ensure fresh produce reaches shelves on time, reducing spoilage and waste. And in healthcare and pharmaceuticals, digital twins monitor and optimize the supply of critical medical supplies and vaccines. These examples highlight how digital twins are driving transformation and how they change supply chains for the better.

Digital twins represent the future of supply chain management, offering businesses unparalleled insights, adaptability, efficiency and, of course, resilience. By embracing this technology, organizations can navigate challenges, seize opportunities, reduce risk and build supply chains that are both resilient and sustainable Question are you ready to embrace the power of digital twins? The time to act is right now. Let's take a more detailed look at the technologies behind digital twins. Digital twins rely on a fusion of advanced technologies to create accurate virtual models of any supply chain and things like the Internet of Things. The sensors collecting real-time data from physical assets such as inventory vehicles and machinery forms part of the foundation of a digital twin, and the various flows of goods and data sensors capturing those flows of goods, whether they go by road, ship, rail, plane, drone, however they travel. And then we've got artificial intelligence and machine learning, creating the algorithms processing data to predict disruptions, optimize processes and simulate the various scenarios with, of course, accuracy. Cloud computing helps because that enables the storage, processing and accessibility of vast amounts of data that digital twins require, ensuring scalability for global supply chains. And we have graph databases, which help model complex supply chain relationships and networks, making visualization easier for decision makers. Then we've got simulation software that allows companies to test scenarios and identify operational improvements without disrupting, of course, the real-world processes and the real-world supply chain. That keeps going while we're still working on the digital twin and testing it. While we're still working on the digital twin and testing it. These technologies work together to create comprehensive, adaptable and data-driven virtual systems.

Tony Hines: 8:52

What about the people, the people who make the digital twins work? What do they look like? What type of people do we need? Well, to implement and manage digital twin systems, organisations need a blend of technical and domain expertise, and the key roles would include Internet of Things specialists, those responsible for deploying and maintaining sensor networks and ensuring seamless data transmission. Then we need the AI and machine learning engineers to develop models and algorithms that enable prediction and scenario simulations. We also need data scientists, the people who analyse the vast data streams generated by digital twins to uncover actionable insights, insights. And we need supply chain analysts, who bridge the gap between the technical findings and operational strategies, turning insights into tangible improvements. And finally, of course, we need IT professionals, who manage the infrastructure, integration scalability and ensure cyber security for sensitive supply chain data. Together, these professionals ensure the smooth operation and continuous improvement of digital twin systems.

Tony Hines: 10:11

So you're probably thinking to yourself right now how much does all this cost? Well, it doesn't come cheap. Digital twins can be expensive. The cost of adopting digital twins varies depending on the complexity and the scale of the supply chain, and this is how it breaks down. There'll be an initial investment in IoT sensors, the Internet of Things, ai, software, simulation platforms and integration expenses, and then there'll be ongoing costs, the maintenance, cloud storage and workforce training to keep systems updated. Estimates suggest that implementing digital twins can range from tens of thousands to several million dollars, tailored to an organization's specific needs. So you've got to be a certain size to make digital twin technology work for you, and it probably is larger organizations presently that will make that investment, and they probably need it more than smaller and medium-sized businesses.

Tony Hines: 11:15

Now you might be asking also, how long does it take to implement? Well, the timeline for deploying a digital twin depends on the organisation's readiness and the intricacy of its supply chain. It typically includes preparation and planning for infrastructure, upgrades and personnel training lasting several months, and then there's the deployment process. Establishing Internet of Things networks, integrating systems and calibrating models might take another few months. Overall, most organisations can expect implementation to take anywhere between six months to a year, and that's after the planning. Factors like organisational complexity and resource availability can influence this timeline.

Tony Hines: 12:02

Digital twins represent a bold leap forward in supply chain innovation, offering unparalleled visibility, predictive insights and optimisation opportunities, but they come at a price. While adoption requires investment in technology and skilled personnel, the benefits far outweigh the challenges. Businesses ready to embrace digital twins can build supply chains that are not only efficient, but resilient and future-proof. Are you prepared to invest in your supply chain's digital transformation? Well, the future might be now. If so Now, because we're talking about digital twins today, I thought it'd be useful to couple this with the brain in the vat, and I'm going to talk about the brain in the vat because it has something to do with the way we think about artificial intelligence, and it's also contemporary in the sense that we have all these tariffs imposed by President Trump, and perhaps the brain in the vat has something to say about that.

Tony Hines: 13:11

So stick around, and I hope you find this interesting. Now I'm going to tell you a story. It's about a thought experiment that explores skepticism, reality and knowledge. It's a modern adaptation of themes found in Cartesian skepticism, particularly in René Descartes' famous question how do I know that what I perceive is real? It's the story of a brain in a vat. This thought experiment was popularized by philosopher Hilary Putnam in the 1980s. This thought experiment was popularised by philosopher Hilary Putnam in the 1980s, specifically in his book Reason, truth and History, published in 1981. Putnam used it to challenge radical scepticism, particularly the idea that one could be completely deceived about reality. His argument builds on earlier sceptical ideas like Descartes' evil demon, the notion of a powerful being that could be manipulating one's perceptions. But let's specifically look at the brain in a vat. In this scenario, we imagine a brain removed from a human body and placed in a vat of nutrients connected to a supercomputer that simulates experiences. The brain, unaware of its condition, believes it's living a normal life, perceiving an external world that does not actually exist. Putnam used the idea to argue against skepticism, claiming that if we were brains in vats, we wouldn't have the necessary referential connection to external reality to even formulate the thought accurately. And the key ideas in A Brain and a Vat are radical scepticism, questions whether we can truly know if our perceptions align with reality, empirical knowledge, if all experience could be simulated, how can we verify external reality and semantic externalism? Putnam argues that meanings depend on real world references. If one were a brain in a vat, they wouldn't even be able to meaningfully say they were a brain in a vat. As we said, it echoes Cartesian skepticism and there are some implications for artificial intelligence and virtual reality, about whether we can simulate experiences and our ability to distinguish reality from illusion. Putnam's thought experiment serves as a challenge to extreme skepticism. Instead of proving whether we are or aren't brains in vets, he argues that the very concept collapses because meaning itself requires a connection to reality. In essence, if we were deceived, our thoughts wouldn't even refer to brains or vets in the way we assume. The idea has far-reaching implications influencing discussions in philosophy, artificial intelligence and cognitive science, and it's often compared to themes in movies like the Matrix. Having said that, we might think of a particular president who appears as an example of a brain in a vat, especially when it comes to tariffs. The brain in a vat analogy is about being disconnected from reality while believing in a constructed version of it. If we apply the metaphor to Trump's tariff policies, some critics argue that the approach might reflect a kind of constructed reality where the economic outcome he envisaged didn't align with the actual global trade dynamics. For example, his tariffs were intended to reduce trade deficits and boost domestic industries, but they've led to higher costs for American consumers and retaliatory measures from other countries. However, the metaphor isn't perfect. Unlike a brain in a vat, trump was actively shaping policy based on his worldview, even if some economists and trade experts found his method flawed. It's more about different interpretations of economic reality than being entirely disconnected from it. However, some think he's delusional and this could be interpreted as disconnected, giving rise to a flawed worldview. This is an interesting take. If we think of delusion as a kind of self-imposed vat, it could explain how someone might construct a worldview disconnected from broader realities. In Trump's case, his tariff policies might reflect a belief in economic strategies that critics argue were overly simplistic or misaligned with global trade dynamics. This disconnect could indeed lead to decisions that seem flawed when viewed through the wider lens. It's fascinating how this brain in a vat metaphor can be applied to real world scenarios like this. It highlights how perception and belief shape actions, even when those beliefs might not fully align with reality. History is full of leaders whose decisions were shaped by their own constructed realities, whether through ideology, misinformation or isolation from dissenting voices. These vats of belief often led to policies or actions that seemed disconnected from the broader realities of their time. We might think of leaders such as Napoleon or Nero, or more recent leaders such as Hitler, and Stalin. There are many examples in history and I'm sure you can think of some. Well, I hope you enjoyed that discussion and it's all about learning something new, isn't it? And I hope you have. We take a little offbeat look sometimes at supply chains and the things that impact supply chains, but we never stray far from human nature and the realities we face, and even in this thought experiment we've done just that. Well, that's it for this episode. I'm Tony Hines. Hope you've enjoyed it. We're signing off and let's hope we don't wake up to yet more tariffs, more market falls and absolute disasters by some leader or other. Can't think of who making everybody's life a misery by forcing his view of the world on everybody else and giving us all a pain. Let's hope we wake up, and it's all a bad dream. I'm Tony Hines, I'm signing off and I'll see you next time in the Chain Reaction Podcast. Bye for now.
