成本因素尽管客户往往不愿意承认,在承运人选择中,运输成本是最重要的决定因素。运输成本因素又包括费率(Rates)、起码计费重量(Minimum Weights)、装卸费用(Loading and Unloading)、包装费用(Packaging)、破损情况(Loss and Damage)和所提供的特殊服务等因素(Special Services Available)。上述因素会因不同企业、产品、情况而异。随着一体化物流管理概念的普及,运输成本因素的要重性有所下降,企业将从总成本角度重新评估运输服务王晓东,胡瑞娟54
运输时间与可靠性运输时间(Transit time )是从托运人(consignor)托运货物到承运人将货物送到收货人(consignee)手中其间所经过的所有时间。包括装卸、中转服务和从始发站到终点站运送服务所需要的所有时间可靠性(Reliability)之承运人所提供的运输服务所用运输时间的一致性王晓东,胡瑞娟55
运输时间与可靠性(2)运输时间与可靠性会影响库存水平和缺货成本。运输时间缩短可以降低库存,可靠性水平提高可以降低库存(安全库存)和缺货成本如果提前期稳定,企业很容易使库存成本最小化,但如果运输时间不一致,企业就不得不增加库存水平。王晓东,胡瑞娟56
运输服务的可得性指客户是否可以使用承运人提供的运输服务运输服务的可得性决定于运输方式的特点,也取决于承运人服务网络的地理范围、服务种类的多样性和服务的频率王晓东,胡瑞娟57
运输服务的安全性多指货物载运输过程中出现的灭失或损坏的情况不同的运输方式、运输线路、运载工具、运输包装方式,以及货物的固有属性、承运人对服务质量的管理能力都会影响货物的破损率和丢失率王晓东,胡瑞娟58
