3th Evolution of the MTM, it aims once again to reduce the processing times of the measures.

Introduction

The third generation of MTM was developed by the Swedish Association of MTM in the years 19701. In the same logic as version 2, it consists of a new simplification of the MTM while remaining reliable at 95%. It allows to be 2 times faster than the MTM2, ie, to analyze in one day, a cycle of operations of 4 minutes.

The principle

  • Handling – H : This is the combination of Get (Release, Reach, Grasp) and Put (Move, Position) of the MTM2. It is a matter of taking control of an object with the hand or fingers and placing it in another place.
  • Transport – T : It is a simplification of the movements move and Position of the MTM1. It is about placing the object in a new place with the hand and the fingers. The difference with Handling is that at the beginning of movement the hand or finger already has control of the object.
  • Step and foot movements (SF): This category combines the movements of the feet and the walking of the MTM2. The remaining definitions are the same as for the MTM2. Whatever the movement, a step, a foot movement… we give a value of 18 TMU.
  • Bending, getting up – B : This category defines a movement where the body changes its vertical position, whether to bend, kneel… In the same way as for the MTM2, whatever the movement, kneel, rise… a time of 61 TMU is allocated.
  • Crank can be understood as a transport. Apply pressure, re-enter or even eye movements are included in handling and transport.
