The Material Handling Institute continues to add to its series of online courses, which are available through the Material Handling Industry of America's Web site (www.mhia.org). The most recent additions include lessons on order picking concepts, designing balanced assembly lines and manufacturing device networks.

Available at no charge, each of the lessons takes about 20 to 45 minutes to complete. Other courses in the series include an introduction to material handling concepts and lessons on justifying capital investments in material handling

MHIA says the lessons as a group are a good way to prepare for the exam candidates must pass to earn its certification in material handling.
