针对网购环境下随机性和延期性影响订单履约的问题.在(Q,R)库存模型的基础上,加入代发履约订单的选项,假设客户需求和订单提前期不确定,客户分为高级和低级两个等级,在确保高级客户的优先权的基础上,设置了一种订单配置策略.采用蒙特卡洛模拟方法,计算特定条件下利润最大化阀值,并对不同客户的订单需求变化对利润最大化阀值的影响进行了灵敏度分析.结果表明:此方法提高了利润和客户服务水平.随机性因素的变动对利润最大化阀值有显著影响.
To deal with the issue of order fulfillment under random and postponement in the online shopping environment.On the basis of the (Q, R) inventory model, add the option to fulfill the order, assuming that the customer demand and order lead time are uncertain, the customer is divided into advanced and Low level two levels, to ensure that the priority of senior customers, based on the set of an order configuration strategy using Monte Carlo simulation method to calculate the profit-maximizing threshold under certain conditions, and different customer orders demand changes The results show that this method improves the profit and customer service level.Stochastic factors have a significant impact on the profit maximization threshold.
