摘要： In example implementations described herein, systems and methods are presented for predicting a throughput for a production line which can involve collecting a current set of production line data associated with a production line; and computing a predicted production throughput for the production line over a production period based on a boosted gradient decision tree algorithm applied to the current set of production line data, wherein the boosted gradient decision tree algorithm is trained on historical production line data.

摘要： In example implementations described herein, there are systems and methods enabling manufacturers to become more efficient by providing a digital tool to track, visualize, quantify, and notify production bottlenecks for quick actions. Some implementations include an apparatus including a processor configured to analyze time-stamp data collected associated with a plurality of elements of an industrial process. The processor may be configured to generate, based on the analyzed time-stamp data, a color coded visualization of the industrial process, where generating the color coded visualization includes associating each of the plurality of elements of the industrial process with a corresponding color indicating a state of an element in the plurality of elements of the industrial process. The processor may further be configured to present, via a display, the generated color coded visualization of the industrial process.

摘要： In some examples, a material may be subject to shot peening of a relatively long duration to improve cavitation erosion resistance of the material. For example, the material surface may be shot peened to cause grain reduction and an increase in hardness to a depth of 60 μm or more, while the surface remains relatively smooth. As one example, the method may include treating a surface of austenitic stainless steel by impacting the surface with shot media for a treatment duration of 15 to 40 minutes at a shot peening intensity corresponding to an Almen strip type A intensity of 5A to 10A.
