TCLEE Lifeline Systems Interdependence Committee (LSIC)

 

Purpose: to understand, model, manage, and exploit the increasingly coupled and complex operations across lifeline systems. This committee will provide technical rigor to develop and document knowledge about novel yet practical approaches to quantify interdependencies and reduce the risk of cascading failures across lifeline systems. The LSIC efforts in the context of the TCLEE vision will also contribute to maintaining national security, economic vitality, public governance, and quality of life. In addition, this committee will enhance risk communication with policy and decision makers that advice private and public entities on complex lifeline system operation and resilience. To this end, protocols for interdependence data collection, restoration strategies and decision processes, and support to emerging recommended practices and future design standards are a core mission of the committee. The committee strives to balance participation of national and international utility owners, operators, and academics.

Current and Future Tasks

Represent TCLEE at the ANSI Homeland Security Standards Panels which is pushing an initiative to establish recommended practices and standards for physical infrastructure design, maintenance and operation to achieve resilience. Leonardo already participated in the inaugural event in Washington D.C. on September 26, 2011; Alex Tang was also present from TCLEE. Leonardo will participate in the second workshop to be held in Washington D.C. on October 10, 2011.

Co-organize a session on lifeline systems lessons learned, interdependencies, and design for the International Symposium on the anniversary of the 2011 Great East Japan Earthquake to be held in Tokyo on March 3-4, 2012. The entire workshop is organized by the Japan Association for Earthquake Engineering along with other Japanese organizations, and the session on lifeline systems is under the leadership of Kazuo Konagai (University of Tokyo) and Yasuko Kwata (Kobe University). Leonardo and Curt met with both Japanese representatives in Memphis during the Annual ASCE conference on Friday, October 21, 2011. This task addresses the commitments of LSIC to the Executive Committee, as per meeting held in February of 2011 at PSOMAS.

Host an LSIC meeting during the Spring of 2012 to strategize how to formalize new protocols for post-event data collection, particularly in terms of interdependence, so that the data provides a foundation for standard development given the interest of ANSI, NIST, and the Department of Homeland Security. This same meeting will include participants from key utilities so as to discuss performance objectives, current standards, and long term technical tasks to move forward with design and operation recommendations for lifeline systems.

LSIC co-hosted a session with the seismic effects committee of SEI on resilience of lifeline systems at the 2011 Structures Congress. Multiple participants expressed interest on joining and contributing to LSIC efforts. These persons will be invited to the 2012 LSIC meeting after the Japanese workshop in March of 2012.

Past Tasks

LSIC on behalf of TCLEE partnered with EERI for a pre-annual EERI conference workshop on challenges and opportunities in Lifeline Systems Engineering as evidenced by the 2010 earthquakes worldwide. The workshop took place on February 9, 2011 from 8 AM to 5 PM in San Diego, CA. An abstract along with a tentative agenda for the workshop is included as an attachment to this report.

LSIC developed a synthesis of key challenges and opportunities stemming from the TCLEE/EERI workshop (see attached). This synthesis has provided discussion points to different initiatives, including San Francisco’s SPUR effort of utility councils, the ANSI/DHS workshops, and the Japanese workshop of 2012. This synthesis was also shared with NEES and NSF.

LSIC proposed a panel session on risk-based design of lifeline systems, but unfortunately was not accepted for the 2012 Structures Congress (see attached proposal).
