Assignee:

International Business Machines Incorporated - Armonk NY

International Classification:

G05B 19/418

US Classification:

705 8, 705 7, 705 9, 705 10, 705 1

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.

International Business Machines Corporation - Armonk NY

International Classification:

G06Q 40/00

US Classification:

705 35, 705 36 R

Abstract:

A computer program product stored on machine readable media including machine readable instructions for selecting a project portfolio from available projects, the instructions for implementing a method include inputting an investment cost and a return for each available project and user-specified constraints; creating a formulation, the formulation comprising the investment cost and the return for each available project, the constraints and variables, the variables comprising for each available project a threshold probability of success and a selection decision; solving the formulation to select the project portfolio and to determine the threshold probability of success for each available project; and outputting the project portfolio and the threshold probability of success for each available project.

International Classification:

G06Q 40/00

US Classification:

705 36R, 705 35, 705 38

Abstract:

A method, system and computer program product for measuring a risk of an asset portfolio. The system estimates a β-level CVaR (Conditional Value-at-Risk) of the asset portfolio by modeling interdependencies between assets in the asset portfolio. The modeling is based on Gaussian copula model.

Inventors:

Pu Huang - Westchester NY, US
Dharmashankar Subramanian - Stamford CT, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06Q 40/00

US Classification:

705 728

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.

International Classification:

G06F 17/30

US Classification:

705008000, 705010000

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.

International Classification:

G06F 17/00

US Classification:

705412

Abstract:

A computer implemented method for risk management in energy services. A plurality of cost components and a set of interrelationships among the plurality of cost components can be compiled. Thereafter, the plurality of cost components and set interrelationships among the plurality of cost components can be provided to a large scale linear module. The cost components and interrelationships among the cost components can be processed utilizing the large scale linear module in order to provide data indicative of one or more optimal decisions for establishing a baseline for contracting dialogues between a consumer and a utility company in favor of the consumer.

International Classification:

G06Q 10/00

US Classification:

705 7

Abstract:

The present invention provides a method and system making it possible to reduce a description of the impact of a disaster on the world at large to measurable, firm-specific operational and financial implications. This makes it possible to bridge the divide between disaster prediction and business planning by facilitating the translation of physical and other effects of a disaster on a business into a dollars-and-cents impact. The present invention also allows a user to evaluate the costs and benefits of various disaster mitigation plans and/or policies and to understand the combined effects of multiple mitigation plans.
