物流配送中心拣选作业的人因工程量化评估

基于人因工程视角,探究电子商务模式下新兴的物流配送中心拣选作业的工程负荷与职业健康,研究选取能量代谢量、心率等指标,量化物流拣选作业环节的劳动强度等级,并利用疲劳强度评估提出合理的作息安排,即当劳动负荷为5km/h时,物流拣选劳动者平均每工作48min后,需要休息6min;当劳动负荷为7km/h时,物流拣选劳动者平均每工作19min后,需要休息6min。该研究拟在改善电子商务模式下物流配送中心衔接不紧密、响应速度慢等瓶颈问题的同时,关注劳动密集型作业环节的工程负荷与职业健康。

Quantitative Evaluation of Human Factors Engineering for Picking Operations in Logistics Distribution Centers

In this paper,from the perspective of human factors engineering,we explored the engineering load and occupational health of the workers in the emerging picking operations in logistics distribution centers under the e-commerce model,quantified the labor intensity level of the logistics picking operation using energy metabolism,heart rate,etc.,and proposed a reasonable working schedule through fatigue intensity assessment,that is,at labor load of 5km/h,the picking operators need to rest 6 minutes after every 48 minutes of work;at labor load of 7km/h,they need to rest 6 minutes for every 19 minutes of work.The research intends to improve on the bottleneck in the operations of logistics distribution centers under the e-commerce model,while drawing attention to the issues of engineering load and occupational health for labor-intensive operations.
