    Abstract: A method for predicting and managing an occurrence of a power outage resulting from human activity, the method comprising the steps of: obtaining at least one short-term notification of a planned human activity event; generating a corrected human activity notification as a function of the short-term notification and data corresponding to power grid information, geographical information relating to the power grid and customers utilizing the power grid, power grid customer information, and/or historical information corresponding to prior power outages resulting from human activity events; generating an outage probability as a function of the corrected human activity notification and trained predictive modeling data; generating an optimization model as a function of the outage probability; and initiating at least one action for mitigating the occurrence of the power outage resulting from human activity as a function of the optimization model.

    Abstract: There are provided a system, a method and a computer program product for generating an optimal preventive maintenance/replacement schedule for a set of assets. The method includes receiving data regarding an asset, said data including a failure rate function of said asset, a cost of preventative maintenance (PM) of said asset, a cost of an asset failure, and a cost of replacing an asset. An optimal number K of preventative maintenance time intervals tk and an indication of a possible replacement is computed and stored for each asset by minimizing a mean cost-rate value function with respect to an electrical age of the asset. A first PM schedule is formed without consideration of labor and budget resource constraints. The method further generates a second maintenance schedule for a system of assets by minimizing a deviation from the optimal PM time intervals subject to the labor and budget resource constraints.
