Transcript of "Methods time measurement (mtm)"

  1. 1. Methods-Time Measurement (MTM) <ul><li>MTM-2 is a system of synthesized MTM data and is the second general level of MTM data </li></ul><ul><ul><li>Consist of </li></ul></ul><ul><ul><ul><li>Single basic MTM motions </li></ul></ul></ul><ul><ul><ul><li>Combinations of basic MTM motions </li></ul></ul></ul><ul><ul><li>Applications </li></ul></ul><ul><ul><ul><li>Work cycle >1’ </li></ul></ul></ul><ul><ul><ul><li>The cycle is not highly repetitive </li></ul></ul></ul><ul><ul><ul><li>manual  not complex or simultaneous hand motions </li></ul></ul></ul><ul><ul><li>Classifications: 11 classes of actions </li></ul></ul><ul><ul><li>Special situations: </li></ul></ul><ul><ul><ul><li>Principle of simultaneous motions </li></ul></ul></ul><ul><ul><ul><li>Principle of limiting motions </li></ul></ul></ul><ul><ul><ul><li>Principle of combined motions </li></ul></ul></ul>

  5. 5. Methods-Time Measurement (MTM) <ul><li>MTM-3 </li></ul><ul><ul><li>Save time at the expense of some accuracy: ±5%,95% </li></ul></ul><ul><ul><li>Not use for operations: eye focus, eye travel time </li></ul></ul><ul><ul><li>4 categories of manual motions: handle, transport, step and foot motions, bend and arise </li></ul></ul><ul><li>MTM-V </li></ul><ul><ul><li>Use in metal cutting operations </li></ul></ul><ul><ul><li>To establish setup time for all typical machine tools </li></ul></ul><ul><li>MTM-C </li></ul><ul><ul><li>Use in baking and insurance industries,2-level system </li></ul></ul><ul><ul><li>To establish time standards for clerical-related works </li></ul></ul>
  6. 6. Methods-Time Measurement (MTM) <ul><li>MTM-M: Use for evaluating operator work using a stereoscopic microscope </li></ul><ul><li>Other specialized MTM systems </li></ul><ul><ul><li>MTM-TE: electronic test, 3-level </li></ul></ul><ul><ul><li>MTM-MEK: electronic test, 3-level, small-lot </li></ul></ul><ul><ul><li>MTM-UAS: describe process, determine allowed times for batch production, 3-level system </li></ul></ul><ul><li>MTM systems comparison </li></ul><ul><ul><li>Criteria: accuracy, number of therbligs utilized, time to analyze a job (at 90% confidence level) </li></ul></ul><ul><ul><li>MTM-2 is the best </li></ul></ul>
  7. 7. Maynard Operation Sequence Technique (MOST) <ul><li>A simplified system: fast establish time standards </li></ul><ul><li>MOST identifies 3 basic sequence models: </li></ul><ul><ul><li>General move: free object movement through the air </li></ul></ul><ul><ul><li>Controlled move: object remains contact with surface or attached to another objects during the movement </li></ul></ul><ul><ul><li>Tool use: use of common hand tools </li></ul></ul><ul><li>Two adaptations: Mini and Maxi MOST </li></ul><ul><ul><li>Mini MOST: identical, short-cycle operations </li></ul></ul><ul><ul><li>Maxi MOST: long-cycle operations </li></ul></ul><ul><li>Both manual and computerized versions </li></ul>
