  • Publication number: 20190104028
    Abstract: Example implementations disclosed herein are directed to monitoring communications networks in real time to ensure that they are performing in a desired fashion. Metrics such as utilization and latency are monitored to ensure that customer SLAs (Service Level Agreements) are met in a timely fashion. To detect problems in advance, example implementations predict the future values of metrics and detect events if the future value violates certain conditions. Example implementations build models that can predict the future values of metrics and analyze historical, near real time and real time streaming data so as to build predictive models.

  • Publication number: 20190057307
    Abstract: Example implementations described herein are directed to systems and methods for estimating the remaining useful life of a component or equipment through the application of models for deriving functions that can express the remaining useful life over time. In an aspect, the failure acceleration time point is determined for a given type of component, and a function is derived based on the application of models on the failure acceleration time point.

  • Publication number: 20180341876
    Abstract: Equipment uptime is getting increasingly important across different industries which seek for new ways of increasing equipment availability. Detecting faults in the system by condition based maintenance (CBM) is not enough, because at the time of fault occurrence, the spare parts might not available or the needed resources (maintainers) are busy. Therefore, prediction failures and estimation of remaining useful life can be necessary. Moreover, not only predictions but also uncertainty in the predictions is critical for decision making. Example implementations described herein are directed to tuning parameters of deep learning network architecture by developing a mechanism to optimize for accuracy and uncertainty simultaneously, thereby achieving better asset availability, maintenance planning and decision making.

  • Patent number: 10109122
    Abstract: Example implementations described herein are directed to a decision-support system for maintenance recommendation that uses analytics technology to evaluate the effectiveness of a maintenance action or a group of actions in improving the performance of equipment and its components, and provide recommendations on which maintenance actions or a group of maintenance actions should be pursued and which should be avoided.

  • Publication number: 20180247207
    Abstract: Example implementations described herein are directed to vehicle scheduling and management, and in particular for estimation of travel times and other activity times. Example implementations can be used to achieve improved vehicle scheduling and utilization based on the provision of accurate expected activity times. Example implementations are further directed to the integration of predictors to provide an estimation of activity time.

  • Patent number: 9957781
    Abstract: A management server is coupled to a plurality of rig systems by a network, each of the rig systems having a plurality of sensors, a rig and a rig node. The management server stores data received from at least one of the plurality of rig systems, the data including values associated with one or more attributes of the rig. The management server derives a model signature for at least one phase from a timeline for at least one rig system based on analytics of information stored in the database and the data, where the model signature includes a set of attributes for the at least one of the plurality of rig systems. In addition, the management server generates a recommendation including one or more actions for planning rig system management operations corresponding to at least one attribute of the set of attributes.

  • Publication number: 20180018364
    Abstract: Systems and methods are directed to providing one or more interfaces to construct a flow and dashboard for data sources connected to an apparatus. In example implementations, a flow building interface and a dashboard designing interface is provided. The interfaces produce flow information and dashboard information, which is used by the apparatus to construct a dashboard, execute a plurality of flows and receive data from one or more external sources to execute the dashboard.

  • Publication number: 20180017467
    Abstract: In some examples, a computing device may generate simulated data based on a physical model of equipment. For example, the simulated data may include a plurality of probability distributions of a plurality of degrees of failure, respectively, for at least one failure mode of the equipment. In addition, the computing device may receive sensor data indicating a measured metric of the equipment. The computing device may compare the received sensor data with the simulated data to determine a failure mode and a degree of failure of the equipment. At least partially based on the determined failure mode and degree of failure of the equipment, the computing device may send at least one of a notification or a control signal.

  • Publication number: 20170169143
    Abstract: Example implementations described herein are directed to predictive maintenance of equipment using data-driven performance degradation modelling and monitoring. Example implementations described herein detect degradation in performance over a period of time, and alert the user when degradation occurs. Through the example implementations, the operator of equipment undergoing predictive maintenance modeling can determine a more optimized time in repairing or replacing the equipment or its components.
