The COVID-19 pandemic has forced public health, supply chain, transportation, government, economic and many other entities to interact in real time. One of the challenges in large systems interacting in this way is that even tiny errors in one system can cause devastating effects across the entire system chain.
Now, Purdue University innovators have come up with a possible solution: a set of patented algorithms that predict, identify, diagnose and prevent abnormalities in large and complex systems.
“It has been proven again and again that large and complex systems can and will fail and cause catastrophic impact,” said Shimon Y. Nof, a Purdue professor of industrial engineering and director of Purdue’s PRISM Center.
“Our technology digests the large amount of data within and across systems and determines the sequence of resolving interconnected issues to minimize damage, prevent the maximum number of errors and conflicts from occurring, and achieve system objectives through interaction with decision makers and experts.”
Applying systems science and data science to solve problems
Nof said this technology would be helpful for smart grids, healthcare systems, supply chains, transportation systems and other distributed systems that deal with ubiquitous abnormalities and exceptions, and are vulnerable to cascading or large amount of failures.
This technology integrates constraint modeling, network science, adaptive algorithms and state-of-the-art decision support systems.
“Our algorithms and solution apply systems science and data science to solve problems that encompass time, space and disciplines, which is the core of industrial engineering,” said Xin Chen, a former graduate student in Nof’s lab who helped create the technology.
Nof said the novelty of the technology lies in three main areas. First, analytical and data mining tools extract underlying network structures of a complex system and determine its unique features. A robust set of algorithms then are analyzed based on the objectives for system performance, structures and features of fault networks in the system.
Finally, algorithms with specific characteristics are applied to manage errors and conflicts to achieve desired system performance.
