Methods, systems and computer program products for resource demand prediction are provided herein. A computer-implemented method includes obtaining historical data logs for activities performed in a distributed service network, the distributed service network comprising a plurality of locations. The method also includes identifying factors influencing resource demand for the distributed service network, determining one or more constraints for specifying activity sequence ordering for activities performed in the distributed service network and generating a statistical model of the distributed service network utilizing the historical data logs, the identified factors and the determined constraints. The method further includes utilizing the statistical model of the distributed service network to determine estimated resource demand for responding to one or more detected outages in the distributed service network, the estimated resource demand being used to allocate resources to the plurality of locations in the distributed service network to respond to the one or more detected outages.

Embodiments of the present invention disclose a method, a computer program product, and a computer system for predictive maintenance of refrigeration cases. A computer collects a temperature time series for a refrigeration case and, based on the temperature time series, learns a refrigeration case signature for both non-frost and defrost cycles. The computer generates features based on the refrigeration case signature and compares the refrigeration case signature to real time, or observed, temperatures and features using a rule-based and/or machine learning framework. Based on determining that the real time data varies beyond a threshold from the refrigeration case signature, the computer identifies a failure symptom of the refrigeration case and diagnoses a root cause of the symptom or failure. In addition, the computer may activate an alarm and open a work order corresponding to the root cause of the symptom or failure.

A method, system, and computer program product for resource management are described. The method includes selecting trouble regions within the service area, generating clustered regions, and training a trouble forecast model for the trouble regions for each type of damage, the training for each trouble region using training data from every trouble region within the clustered region associated with the trouble region. The method also includes applying the trouble forecast model for each trouble region within the service area for each type of damage, determining a trouble forecast for the service area for each type of damage based on the trouble forecast for each of the trouble regions within the service area, and determining a job forecast for the service area based on the trouble forecast for the service area, wherein the managing resources is based on the job forecast for the service area.

Systems and methods for determining a chip yield are disclosed. One system includes a first level integration solver and a second level integration solver. The first level integration solver is configured to obtain a first probability distribution function modeling variations within a chip and to perform a discontinuous first level integration with the first probability distribution function. In addition, the second level integration solver is implemented by a hardware processor and is configured to perform a continuous second level integration based on a second probability distribution function modeling variations between dies to determine the chip yield.
