Research output: Contribution to conferencePaperpeer-review


In manual material-handling environments, a large number of workforce injuries are sustained each year and these injuries are often of a severe nature. This paper is concerned with finding a job rotation methodology to reduce the potential of workforce injuries. Under varied conditions of lifting task demands, a single deterministic rotation plan may not be a desirable solution. The importance of obtaining task demand information at different decision stages and properly integrating it with worker rotation plans is illustrated with a number of example problems. The results show that real-time information provides substantial benefits in reducing the maximum number of worker lost days due to low back injuries.
