What is IPSS?

How can infrastructure become more resilient? 

How can we reduce the financial costs associated with resiliency, and best use available funds to mitigate long- and short-term consequences? 

How do we know what the risks are and how do we manage those risks? 

Resilient Analytics answers these questions with the Infrastructure Planning Support System (IPSS).

IPSS is a unique, first-of-its-kind system that performs engineering analysis within a broader resiliency perspective. IPSS models infrastructure vulnerability to future climate and weather conditions, considers specific adaptation scenarios, and provides a cost- benefit based risk analysis. IPSS draws its data from a range of climate science projections, engineering and materials studies, and environmental research to provide users with decision support that is based in real-world risk scenarios. 

IPSS provides decision support at multiple spatial and temporal scales. From individual assets to national studies, IPSS can focus on multiple portfolio sizes and compositions. These studies can be run at detailed emergency and budget planning timeframes as well as for long-term regional planning perspectives.

How It Works


Impact Identification

IPSS first determines the future climate changes— stressors—that will negatively impact the infrastructure. The program utilizes a wide range of climate models to establish future variations in aspects of climate such as temperature, precipitation and flooding. 


Vulnerability Analysis

Next, IPSS analyzes the specific impacts those stressors will have on the infrastructure in question, such as roads, or buildings, or bridges. The impact is measured as a reduction in the original expected design-life as a result of the climate-induced degradation 


Adaptation Planning

Climate change impact is quantified as a fiscal cost and risk, which varies depending on which resilience strategy is employed. IPSS generates a “no adapt” strategy, which calculates the cost of retaining the original design-life through increased repair and maintenance costs. IPSS compares this with a “resiliency” strategy, which calculates the cost of modifying designs and operations to  mitigate the effects of projected changes to climate patterns.
