Abstract: To integrate human factors into the process of unit facilities layout,Rapid Entire Body Assessment(REBA)was introduced to quantitatively analyze the human Occupational Musculoskeletal Injury(OMI)risk in Manual Material Handling(MMH)work.An optimization model of unit facilities layout integrating human factors was proposed by combining the human factors with logistic factors.Furthermore,the simplified particle swarm optimization algorithm was adopted to solve the model and improve its optimization efficiency and accuracy.By taking the numerical control machining unit of a military enterprise as a case,the model was used to design and optimize the current unit facilities layout and the scheme was simulated with ergonomic modules of Delmia.The result showed that by taking human factors into account in the course of designing the facility layout could not only improve the overall efficiency of the manufacturing system,but also reduce workers'OMI risk in MMH,which was conducive to achieve the interconnection between human and manufacturing resources and the humanization of manufacturing process.
