Since its inception, ARPI has supported a number of technology development efforts focused on crisis action planning. In this article we provide a synopsis of the progress made in a selected subset of the technologies that will need to contribute to making the ARPI vision a reality. We focus on ARPl-supported research that is providing critical advances in the enabling technology areas of plan generation, scheduling and temporal reasoning, plan analysis, and overall supporting infrastructure. We conclude with a discussion of several important remaining technology challenges.
