员工学习-遗忘效应对O2O超市订单分批拣选效率的影响研究

Influence of pickers’learning and forgetting effects towards order batching efficiency of online-to-offline supermarket

该文将员工的学习-遗忘效应引入O2O超市订单分批拣选问题中,研究学习-遗忘效应对拣选效率的影响,以总服务时间最小为目标建立订单分批优化模型,分析构建考虑学习-遗忘效应的三阶段服务时间表达式,并采用改进种子算法求解.该研究设计两种典型的员工排班方案S1和S2,并通过仿真实验深入探讨学习-遗忘效应对S1和S2拣选效率的综合影响.实验结果表明,S2方案的拣选效率优于S1;当员工休假天数固定时,安排长休假并减少休假次数有利于降低遗忘效应的负面影响;提高员工的学习能力比减弱遗忘效应更能有效提升拣选效率.论文拓展了学习和遗忘效应在订单拣选领域的研究,并为管理者制定员工排班策略提出实质性建议.

In this paper employees’learning-forgetting effects was introduced into the order batching problem of online-to-offline supermarkets,and the influence of learning-forgetting effects towards order picking efficiency was analyzed.The order batching optimization model was formulated to minimize the total service time,and the three-stage service time expression considering learning-forgetting effects was established.The improved seed algorithm was proposed to solve the model.Two common picker scheduling strategies S1 and S2 were proposed and compared under the model.Through a series of simulation experiments,it’s found that S1 is better performed than S2.When the rest days are fixed,longer consecutive rest days and fewer rest times are able to weaken the negative influence of forgetting and are more beneficial to the picking performance.Moreover,compared to lower forgetting effects,higher learning abilities are more dominant to affect the picking performance.This paper expands the study of learning and forgetting effects into order picking field,and provides substantive suggestions for managers to formulate the employee scheduling strategy.
