A research consortium at Blackbridge Institute Polytechnic and Arts has unveiled a new dynamic simulation platform designed to map the complex, cascading failures that propagate through global supply chains in the wake of major geopolitical events. The platform, named ‘Cascade’, is the flagship output of the Institute’s two-year Systemic Resilience Initiative. It moves beyond traditional economic modelling by integrating unconventional data sources and agent-based simulation to provide a granular, real-time analysis of systemic risk. The initial findings, focusing on the global semiconductor supply chain, were presented at a major international economics conference last week.
The initiative was born out of a recognition that existing risk models are often inadequate for the 21st-century commercial landscape. Most conventional models are static, treating supply chains as linear and predictable systems. They struggle to account for the non-linear, often unpredictable, second and third-order effects of sudden shocks, such as targeted trade sanctions, the sudden nationalisation of a critical resource, or a cybersecurity breach at a key logistics hub. Cascade was engineered to simulate this very complexity.
At the heart of the platform is a sophisticated fusion of network theory and agent-based computational modelling. Rather than looking at trade flows from a purely macroeconomic perspective, Cascade models a supply chain as a dynamic network of individual ‘agents’. These agents—representing component suppliers, manufacturing plants, shipping companies, and even regulatory bodies—are programmed with complex decision-making rules derived from firm-level data and strategic management theory. The platform simulates how these individual agents react to a crisis, allowing researchers to observe how their independent, often self-interested, decisions can amplify an initial shock across the entire network.
Professor Eva Kallas of the Global Political Economy & Governance discipline, who provides geopolitical context for the initiative, explains the necessity of this micro-level approach. “A government might impose a sanction on a single, seemingly minor, chemical precursor. A traditional model might register a small dip in output. What it misses is the panic-buying that follows among firms who rely on that chemical, the logistics bottlenecks created as companies scramble for alternate shipping routes, and the decision by a third-country’s port authority to halt shipments over compliance fears. Cascade allows us to see these echoes and trace how a pebble tossed in one part of the world can create a tidal wave in another.”
A key innovation of the Cascade platform is the diversity of its data inputs. The Computational Engineering team developed a sophisticated ingestion engine that moves beyond standard trade statistics. It processes real-time satellite imagery to monitor activity at key industrial sites, analyses anonymised vessel-tracking data to detect deviations in shipping patterns, and even performs sentiment analysis on specialised policy forums and industry publications to gauge shifts in corporate and regulatory mood.
This data integration proved to be one of the project’s most formidable challenges. A postgraduate researcher from the engineering team described the process as “less about elegant algorithms and more about a determined, brute-force effort to harmonise wildly different, and often messy, datasets. For months, our primary task was to teach the system how to correctly interpret a vaguely worded policy directive from one source alongside a precise GPS coordinate from another. It was a humbling lesson in the ambiguity of real-world information.”
Faculty from the Strategic Business & Entrepreneurship discipline have been instrumental in translating the platform’s outputs into actionable insights for industry. They have used the simulations to stress-test various corporate resilience strategies, such as multi-sourcing, regionalisation, and increasing buffer inventories. The initial findings on the semiconductor industry were particularly revealing.
“We found several counter-intuitive results,” noted a Senior Lecturer in Strategic Management. “For instance, in some scenarios, a company’s decision to rapidly diversify its supplier base in response to a minor political scare actually increased its overall risk profile by introducing new, less-vetted partners into its network. The platform shows that in a complex system, well-intentioned, intuitive reactions can sometimes be the wrong ones. It provides a tool for businesses to test their assumptions in a safe, virtual environment before a real crisis hits.”
Despite its power, the team is candid about the platform’s limitations. It is a sophisticated tool for exploring possibilities, not a crystal ball for predicting the future with certainty. The model’s accuracy is highly dependent on the quality of its input data, and truly capturing the nuances of human psychology and corporate decision-making under extreme duress remains an ongoing research frontier.
The Systemic Resilience Initiative is now focused on expanding the Cascade platform to model other critical sectors, including pharmaceuticals and rare-earth minerals. By making their methodology and core findings public, the Blackbridge team hopes to spur a wider conversation among academics, industry leaders, and policymakers about the hidden fragilities in the global systems upon which modern life depends. The project is a stark illustration that in our interconnected world, understanding the network is no longer an academic exercise, but a fundamental prerequisite for survival.
