Abstract

Some embodiments include a computer-implemented restoration work plan system and method comprising a processor, a non-transitory computer-readable storage medium in data communication with the processor, and a service restoration management system executable by the processor, and configured to prepare a first distribution system operations storm outage prediction project model forecast substantially in real time based at least in part on a weather forecast. Some embodiments include calculating and displaying an expected outage category level substantially in real time for each division based on the weather forecast, and resource numbers comprising the number of personnel needed to respond to outages and the number of crew needed to repair outages. Some embodiments include calculating and displaying an estimated time of repair within the repair plan based at least in part on a historical productivity assumption, the productivity assumption including a historical rate of assessment and repair and percentage of outages requiring repair.
