Question

英语翻译
When products are delivered from the supplier to the consumer,transportation costs are incurred.In the traditional economic order quantity (EOQ) model,the transportation cost is calculated together with the production cost,or with the ordering cost.However,in a practical logistic system,the transportation cost of a vehicle includes both of the fixed cost and the variable cost.The fixed cost,which is considered to be a constant sum in each period,refers to some necessary expenses such as parking fare and rewards to the driver.As to the variable cost,it depends mainly on the oil consumed,which is related directly to the distance traveled.In short,considering the real condition,it is unreasonable to assume that the transportation cost is proportional to the quantity delivered or is a constant sum.For example,the optimal ordering quantity yp gained according to the general EOQ formula may be partly loaded by the vehicles and the cost of the logistic system may not be the lowest.
In this study,we address the problem of minimizing the production,inventory and transportation costs for a supplier–retailer logistic system.Unlike most of the prior inventory models,both of the fixed cost and the variable cost of the vehicles are accounted in the model.

Answer 1

当产品交付从供应商到消费者,运输成本费用.在传统的经济订货量（的EOQ ）模型,运输成本计算,再加上生产成本,或与订购成本.但是,在实际的物流系统,运输成本的车辆,既包括对固定费用和可变成本.固定的成本,这被认为是一个不断总结,在每个时期,是指一些必要的开支,如停车收费,并奖励给司机.作为向可变成本,它主要取决于对石油的消费,这是直接相关的距离.在短期,考虑到实际情况,这是不合理的假设运输成本是成正比的数量,或交付是一个不断总结.举例来说,最优订购量的YP取得根据一般的EOQ公式可能部分装载由车辆和成本的物流系统,未必是最低的.
在这项研究中,我们处理这个问题,尽量减少生产,库存和运输成本,为供应商-零售商的后勤系统.不同于大多数的事先存货模型,这两种固定费用和可变费用的车辆占在模型中.
