The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.
VEX V5 is a STEM learning system designed by VEX Robotics and the REC Foundation to help middle and high school students develop problem-solving and computational thinking skills. [9] It was introduced at the VEX Robotics World Championship in April 2019 as a replacement for a previous system called VEX EDR (VEX Cortex).
Transmission internals for a 2009 Volkswagen Golf. A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.
Sometimes a feedback (or a reaction) does not occur immediately – the process contains delays. Any system can be drawn as a diagram set up with circles of causality – including actions, feedbacks and delays. [1] Reinforcing feedback (or amplifying feedback) accelerates the given trend of a process. If the trend is ascending, the reinforcing ...
Example of a worksheet for structured problem solving and continuous improvement. A3 problem solving is a structured problem-solving and continuous-improvement approach, first employed at Toyota and typically used by lean manufacturing practitioners. [1]
The viable system model (VSM) is a model of the organizational structure of any autonomous system capable of producing itself. It is an implementation of viable system theory . At the biological level, this model is correspondent to autopoiesis .
war die Suche nach Hemmnissen und Problemen bei der Einführung von „lean management“-Strukturen auf den drei Ebenen „Mitarbeiter“, „Führungskraft“ und „Unternehmensleitung“. Auf der linken Tafelseite wurden die Hemmnisse notiert, auf der rechten „Lösungsvorschläge für eine positive Einflussnahme“. Die Ergebnisse
Key critics of the command-and-control management ethos and techniques include members of the systems-thinking community and associated thinkers, including W. Edwards Deming, [1] John Seddon, [2] Kōnosuke Matsushita, [3] Taiichi Ohno, Russell L. Ackoff, [4] Donella Meadows, [5] Alfie Kohn, [6] and the outspoken Vanguard Method practitioner ...
