Charles River Analytics (CRA) has received additional funding from the US Navy (USN) to build a System for Naval Data Aggregation and Planning with Probabilistic Reasoning (SNAPPR), the company announced on 8 July. CRA has partnered with Raytheon Integrated Defense Systems for the three-year follow-on contract, valued at nearly $1.5 million.

SNAPPR creates probabilistic models of naval system components, the environment in which they operate and the missions that they serve, to help operators understand the Operational Availability (Ao) of hardware components onboard a naval vessel.

AO is crucial to a mission’s success,” explained CRA Technical Lead on SNAPPR, Kenny Lu. “Current Ao hardware protocols can result in unnecessary maintenance, causing crippling delays in mission-critical functions. SNAPPR’s probabilistic model produces real-time reasoning, estimates and predictions of Ao to generate an optimised preventative maintenance schedule.”

SNAPPR is a further advance in CRA’s growing portfolio of solutions in predictive health maintenance. Under the EMC2 and POWERED efforts, the company employed probabilistic programming to help predict resource gaps and faults in military operations systems. These efforts are powered by an open-source, probabilistic programming language for probabilistic modelling, known as FIGARO.
