以汽车行业物流为参考,通过分析周转包装投入量问题的影响因素,建立了其计算模型;结合案例,验证了模型的正确性,说明了安全系数s 取值大小的选择方法及影响,讨论了计算模型在项目年产量相同和不同,以及内外周转包装使用寿命不同时的应用情况。该计算模型可准确评估周转包装投入量及包装成本,避免因投入不足或过多而导致周转不灵或成本增加,从而造成浪费,也可推广应用于食品、农副产品等行业物流配送的周转包装投入。

The calculation model was established through analyzing the influencing factors of returnable packaging investment volume based on the logistics of automobile industry. Combined with case study, the correctness of calculation model was validated. The selection and effect of the value of its safety factors were explained, and the application of the calculation model in three conditions was discussed, which were same annual volume of project, different annual volume of project, and different lifetime between outside and inside returnable packaging. This calculation model can evaluate the returnable packaging investment volume and packaging cost exactly, which will avoid packaging shortage or packaging cost increasing and waste caused by insufficient or excessive investment. The model can also be used to calculate the returnable packaging investment volume in other industries' logistics, such as food, agricultural and sideline products industries.
