Space, Time and Ergonomic Assessment of Order Picking Using Horizontal Carousel

The efficiency of order picking operations can be enhanced by different automated storage/retrieval systems (AS/RS) based on the “part-to-picker” principle. One such system is a horizontal carousel, a rotating rack that delivers parts to the operator. Apart from space and time reduction related benefits, horizontal carousels are often marketed as well as better ergonomic systems compared to traditional shelving rack systems. However, not many papers deal with a quantitative comparison of horizontal carousels with shelving systems that are much more used for small parts order picking. Especially there is a lack of papers analyzing ergonomics of horizontal carousels. In this paper, horizontal carousels are briefly presented, followed by methods to compare horizontal carousels with shelving systems in terms of space, time and ergonomics. For ergonomic assessment, a method of energy expenditure calculation is used. Presented methods can serve as tools for managers for additional justification of horizontal arousel’s implementation.
