The Guarino Infrastructure Dependency Metric, Paper IV. Winter Storm Elliott: Does the Buffer Group Travel?

Papers I to III of this series built the buffer group ΠB = Ta/Tx for the edge between two infrastructure nodes, tested it plant by plant on the February 2021 Texas chain, and priced its hours with a cost group ΠC = ca/(vCd), all on one event. This paper reads a second. Winter Storm Elliott, 22 to 26 December 2022, ran...

The Guarino Infrastructure Dependency Metric, Paper VI. Winter Storm Heather: A Blind Test on the Texas Chain

Paper V found that the buffer group ΠB = Ta/Tx, applied to cell sites whose buffers are unknown, predicted worse than exposure alone in two blind storms, and traced the failure to the unknown numerator. This paper moves the test to an edge where the numerator is written down. Since 1 December 2023 every ERCOT generatio...

The Guarino Infrastructure Dependency Metric: Buffered Edges as a Complete Dimensionless Basis for Interdependent Infrastructure

Paper I of the Guarino Infrastructure Dependency Metric (GIDM). Infrastructure fails in chains. The February 2021 freeze in Texas began at frozen wellheads, ran through load-shed gas processing plants, took 61,800 MW of generation offline, and ended in boil-water notices for almost 18 million people. Existing resilienc...

The Guarino Infrastructure Dependency Metric, Paper III: The Water Edge at the Tap and the Price of an Hour of Autonomy

Paper III of the Guarino Infrastructure Dependency Metric (GIDM). Abstract. Papers I and II of this series derived the buffer group ΠB = Ta/Tx on every edge of an infrastructure dependency graph and tested it on the February 2021 Texas chain, leaving two things open: the water edge below the tap, which Paper I could va...

The Guarino Infrastructure Dependency Metric, Paper V. Hurricane Helene: The Communications Edge

Papers I to IV of this series built the buffer group ΠB = Ta/Tx for the edge between two infrastructure nodes, tested it on the gas-to-power-to-water chain in two winter storms, and priced its hours with a cost group ΠC = ca/(v Cd). This paper takes it to a third hazard and a fourth node. Hurricane Helene, 26 September...
