SCHOOL OF INDUSTRIAL ENGINEERING Why model? Environment may not allow testing with people System may not yet exist Designing a new automobile cockpit Designing a new workstation Anthropometric range Environment may be too complex to conduct a simple analysis Automobile cockpit • Reach • Visual range Need to check all biomechanical stresses

SCHOOL OF INDUSTRIAL ENGINEERING Modeling More complicated analyses require the use of more complex  models of humans There are currently many very good 3D packages for this purpose 3DSSPP (U. of Michigan,  http://www.engin.umich.edu/dept/ioe/3DSSPP/ ) Jack (/Jill) - more capable but more difficult to learn (more importantly, it  is available to Purdue students). A manual will be posted on Blackboard.

SCHOOL OF INDUSTRIAL ENGINEERING Exercise - modeling Consider the use of a simple computer model of a person – for  example the cashier station from a few lectures ago. Write down (some) of the outputs we needed for our analysis, and  consider how these would appear as output from a computer  program To help, here is the diagram:

3D SSPP Example Application In this example, an analysis will be done of a worker lifting a heavy box and preparing to  place the box on a dolly. This is a typical task for a person working in a warehouse.  Similar analyses can be done for a wide variety of tasks. http://www.engin.umich.edu/dept/ioe/3DSSPP/example.html
