Quantification of Scenarios and Stakeholders Influencing Priorities for Risk Mitigation in Infrastructure Systems

Abstract

Addressing scenarios of emergent and future conditions is essential to develop robust priorities for infrastructure systems including energy, water, communications, and transportation. Such scenarios represent the perspectives, expertise, and interests of diverse stakeholders. Strategic priority setting must thus consider several perspectives, such as regulatory, regional, local, planning, operations, and maintenance. This paper will demonstrate scenario analysis with multicriteria analysis to achieve the consensus of stakeholders on the priorities for reducing vulnerabilities of a large-scale system. The approach integrates scenario identification, priority-setting analysis, stakeholder preferences, and consensus building. It will be demonstrated on a 10,000-km (6000-mi) critical multimodal transportation network that is vulnerable to nearby real estate and land uses.
