that is designed to assist communities in resilience planning.  The specific challenges addressed by NIST ARC relate to the breadth, large scale, and interdependencies of the <em>community resilience planning system</em>鈥攖hose elements of our physical, social, and economic systems that determine a community鈥檚 resilience.  Given hazard and interdependency information, and socio-economic data, NIST ARC outputs <em>alternative sets of actions across the community</em> that can be taken to meet user-specified resilience and other targets (e.g., cost).  The goal of NIST ARC is to decrease a community鈥檚 burden in developing viable, sound alternatives for stakeholder consideration and to provide useful starting points for further, more detailed analysis.</p> <p>NIST ARC is designed to assist a <em>collaborative planning team</em> in the identification of solutions as outlined in NIST鈥檚 <a href="https://web.archive.org/web/20240716000235/https://www.nist.gov/el/resilience/community-resilience-planning-guide"><em>Community Resilience Planning Guide for Buildings and Infrastructure Systems</em></a>.  The target user of NIST ARC is an analyst working in close collaboration with the planning team.  The analyst would facilitate the team鈥檚 interactive use of NIST ARC, including refinement of targets and imposition of new constraints to address stakeholder comments or concerns, and to explore tradeoffs.</p> <p><span><span><span>Alternatives found with NIST ARC are intended to serve as effective starting points for further analysis and refinement, including with other tools.  Other NIST-funded tools include the Center for Risk-Based Community Resilience Planning (CoE)-developed </span><a href="https://web.archive.org/web/20240716000235/http://resilience.colostate.edu/in_core.shtml"><span>Interdependent Networked Community Resilience Modeling Environment

incorporation of feedback from communities while also encouraging contributions from fellow researchers.  Future versions of NIST ARC will enable the capture of more components of the community
