This paper investigates the application of Group Method of Data Handling (GMDH) in modeling of Manual Materials Handling Activities (MMHA). GMDH is a powerful heuristic technique that can be applied for modeling complex non-linear systems with a large number of variables and parameters, structural uncertainties, and/or a limited amount of collected data. The technique explains the behaviour of a system based on input-output data and in that respect is similar to statistical modeling methods (Ivakhnenko, 1970; 1971).
