Other early development work focused on ergonomic analysis of
manual materials handling and lifting tasks. One of these early
ergonomic expert systems was LIFTAN, designed for the analysis of
manual lifting tasks (Karwowski et al., 1986a,b; 1987). This system
utilized a knowledge base comprised of 149 rules: 34 were taskrelated
risk-analysis rules, 51 were operator-related risk rules, 30
were job redesign recommendations and 34 were operator-related
explanations. The domain content of the knowledge base was
derived from relevant published studies on manual lifting, biomechanics,
anthropometrics, work physiology and epidemiology.
LIFTAN also comprised an inference mechanism and a human
interface to guide the user through the information needed by the
