Abstract: The present invention includes a computing system for evaluating a quality and risk-robustness of a utility company's capacity resource plan (CRP). The computing system computes a net present value of a total cost distribution of the CRP. The computing system calculates a standardized risk measure defined over the net present value. The computing system computes a resource plan that minimizes the standardized risk measure. Then, the computing system compares the standardized risk measure and the resource plan.

Abstract: The system and method of the present disclosure allow the user to enumerate a set of risk factors for each financial metric time-profile projection, and respond to a set of questions that is linear in the number of risk factors. In one embodiment, the risk elicitation on each risk factor uses user input of likelihood of risk and impact and/or severity. On each of the risk factors for any given nominal, financial projection estimate, the inputs are systematically converted into a net impact distribution for that nominal, financial estimate.

Abstract: A method of price forecasting in an electrical energy supply network and/or load (energy demand) forecasting of a given consumer of electrical energy, in the context of an electrical energy supply network that is adapted to supply electrical energy to a number consumers connected to the network. The method includes developing a multi-regime, regime switching stochastic model for determining day ahead/spot market energy prices using at least one historical profile and subjective opinion from at least one expert; and the multiple regimes correspond to a number of combinations of physical factors. A regime is identifiable by at least three factors. The method thus facilitates identifying the optimal mix of energy hedge and exposure to day ahead/spot market prices for deriving economic benefits in overall energy expenditure.

Abstract: A method and system for workforce planning in one aspect provide an optimization model that produce, based on the availability profile and the demand profile of skill types, a workforce plan recommending a combination of actions. The combination of actions may include hiring, contracting and cross-training. The optimization model considers constraints such as minimum residence time that a resource unit needs to spend in a skill-type that it gets cross-trained into or hired into, minimum acceptable contracting duration for a contracted skill type, first order and higher orders of cross-training for a skill type, with lead-time for training, one or more system rules associated with transfer sequences, or targets on service levels and resource utilization, or combinations thereof, in determining the workforce plan.

The optimal solution is determined by generating a sequence of solutions that converge to the optimal solution.

Abstract: Wireless communications methods and systems. Metrics for measuring performance of a wireless system are generated and compared to metrics generated with an idealized simulation of the system. If the actual system performance falls below a predetermined level, the system may be reconfigured to improve performance using a centralized or decentralized method for such configuration.

Abstract: A method, system and article of manufacture are disclosed for modeling a plan for deployment of smart meters in a plurality of locations that are attached to a grid operated by an energy provider that supplies energy to said locations, wherein the smart meters are used to measure the energy supplied by the energy provider to said locations. The method comprises the steps of using a market diffusion model to create a time-varying user adoption profile, including estimating the time lagged benefits realized from deployment of the smart meters; and estimating a response in the demand for said energy due to adoption of the smart meters. A program is used to capture the time-lagged benefits and a given set of constrains for a chosen planning time horizon to develop a meter deployment plan across the various locations and over that planning horizon.

Abstract: The availability of relevant business resources, or supply, during a global crisis or disruption are estimated by using a forecast of a baseline supply of human resources and various forms of infrastructure and raw materials for a firm as input. That forecast is corrected to account for the impact of a crisis or other disruption, and a corrected forecast as output is provided. The corrected forecast reflects changes in the availability of business resources due to the crisis or disruption, dependencies between resources, as well as any mitigating effects resulting from the implementation of mitigation policies.
