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.

摘要： 为了在单元设施布局过程中考虑人因学因素,引入快速全身评估法对单元中手工搬运作业的人体职业性肌肉骨骼损伤风险进行了量化分析,并结合物流因素提出了考虑人因的单元设施布局优化模型。为了提高优化效率和精度,采用简化的粒子群算法对模型进行求解。以某军工企业数控加工单元为实例,利用该模型进行单元设施布局优化设计,并利用Delmia软件的人因模块进行仿真,验证了在设施布局设计时综合考虑人因和物流因素,不仅可以提高生产系统的整体效率、降低工人手工搬运作业的人体肌肉骨骼累积损伤风险,更有利于实现人与制造资源的互联及制造过程的人性化。
