December 5 - 6, 2018 - CRISP Grantees Workshop

The PRAISys platform goes public, when the PRAISys team has attended the CRISP Grantees Workshop in George Mason University at Arlington, VA, sponsored by the National Science Foundation on December 5-6, 2018. The PRAISys team presented a 12-minute presentation and a poster at the workshop. The poster described features of the PRAISys platform, particularly focusing on interdependencies and uncertainties, serving as a decision support tool for disaster management. PRAISys is a joint effort that has involved 43 researchers to date (and growing) at Lehigh University and partner institutions. More interesting findings and publications are coming out.
