Abstract

Abstract This article aims to investigate the impact of allowable human energy expenditure (HEE) of order pickers on the throughput of workers in manual order zone picking systems MOP. The method used in this research is the Monte Carlo simulation, used while considering many human and job factors. The results showed that a worker’s gender and an item’s weight have little effect on the HEE. On the other hand, body weight, walking speed, distance travelled, and the targeted zone significantly impacted the HEE, rest allowance, and throughput. For example, male pickers at a weight of 75 kg can move up to speed to 1 m/s and pick up items weighing up to 5 kg without reaching the allowable HEE rate, equal to 4.3 kcal/min, and, thus, no rest is needed. Female pickers at a weight of 75 kg reach the allowable HEE rate, equal to 2.6 kcal/min, at a very low speed of approximately 0.1 m/s when picking up items up to 5 kg, and, thus, frequent rest is needed, which leads to low throughput. To increase the throughput of female pickers, they can be assigned to pick up lighter items. Utilising Monte Carlo simulation to evaluate the HEE in MOP while considering many factors.

人的能量消耗对订单拣选生产率的影响:分区拣货系统中的蒙特卡罗模拟研究
摘要 本文旨在研究订单拣选工的允许人的能量消耗(HEE)对人工订单区拣选系统澳门威尼斯人官网人吞吐量的影响。本研究采用蒙特卡洛模拟法,同时考虑了许多人为因素和工作因素。结果表明,工人的性别和物品的重量对 HEE 的影响很小。另一方面,体重、行走速度、行走距离和目标区域对 HEE、休息时间和吞吐量有很大影响。例如,体重为 75 千克的男性采摘者可以以每秒 1 米的速度采摘重达 5 千克的物品,而不会达到允许的 HEE(相当于每分钟 4.3 千卡),因此无需休息。体重为 75 千克的女拾荒者在拾取 5 千克以下的物品时,以约 0.1 米/秒的极低速度就能达到允许的 HEE 率(相当于 2.6 千卡/分钟),因此需要经常休息,从而导致吞吐量较低。为了提高女拣工的产量,可以让她们拣拾较轻的物品。利用蒙特卡洛模拟评估澳门威尼斯人线上娱乐场的 HEE,同时考虑多种因素。
