Abstract

Abstract: In order to prevent workers from suffering from work-related musculoskeletal disorders due to fatigue in manual handling, a bi-objective model was built about handling time and energy consumption based on economics and ergonomics. An interactive simulation platform was designed by using IGRIP/ERGO and Matlab are used to carry out simulation experiments. Through the simulation of the model,the case was executed about manual materials handling in an automobile brake pad manufacturing company. The optimal solution was gotten. The results show that both the material quantity and the production procedure have significant effects on energy consumption and handling time, that there is a negative correlation between the change rate of energy consumption and time, that the optimal solution can be usually obtained between productivity and ergonomics according to the proposed bi-objective model, and that the interactive simulation platform is helpful in controlling and preventing WMSDs for workers in modern production operation, and in making the production environment and operation design in accordance with ergonomics.
