IBM's research laboratories in the U.S. and India have fine-tuned technology to help model and manage natural disasters such as wildfires, floods and diseases.
The new enhancements are to a budgeting system being developed by IBM, starting from 2003, for managing natural disasters, with a focus on better preparedness for future uncertain disaster scenarios. The optimization models and algorithms were initially prototyped on a large U.S. government program, to deploy a large number of critical resources to a range of disaster event scenarios, said Gyana Parija, lead researcher in the Analytics and Optimization Research team at IBM India Research Laboratory in Delhi, India.
That system, however, only generated a single solution for each disaster scenario. The new enhancements include a decision-support system to allow for multiple solutions to each disaster scenario, so that a range of alternatives can be generated by the system, IBM said Tuesday.
A model that supports multiple criteria can be used effectively where there is a contention for resources, as when then is more than one disaster demanding resources, according to Parija. "Typically what happens in a particular disaster scenario is that you would have different budget alternatives, and at different budget alternatives, you would like to explore what kind of resource organization you can have," he added.
IBM's stochastic optimization model can also be used in applications other than disaster management, such as asset liabilities management problems in financial services and other business sectors, Parija added.
