Publication number: 20210240172Abstract: Various embodiments are described for dynamic value stream management. A computing environment is directed to receive a stream of metrics from station computing devices each positioned at a station in a manufacturing process, where individual ones of the station computing devices have a sensor configured to generate metrics. The computing environment may determine an optimal allocation of resources for each of the stations in the manufacturing process based at least in part on the metrics. If a cycle time of a station falls below a threshold, personnel from another satisfactorily-performing station may be reassigned to the station based on cross-training metrics. A recommended action for the stations may be determined and presented in a display device.Type: ApplicationFiled: January 29, 2021Publication date: August 5, 2021Inventors: Himanshu Srivastava, Brandon Flexsenhar
