Presentation Transcript

  1. Psy 552 Ergonomics & Biomechanics Lecture 15

  2. The Multitask Equations • The multitask procedure considers the collective effects of all the tasks. • The procedure calculates the cumulative effects defined as:

  3. Sum of the Change in LI

  4. The multitask procedure • 1. Compute the Frequency-Independent Recommended Weight Limit (FIRWL) and Single-Task Recommended Weight Limit (STRWL) for each task. • 2. Compute the Frequency-Independent Lifting Index (FILI) and Single-Task Lifting Index (STLI) for each task. • 3. Compute the Composite Lifting Index (CLI) for the overall job.

  5. Multitask Example
