根据企业规模和运输成本对削片作业进行优化，得到最佳削片发动机尺寸。通过提高削片机的机器利用率，可以降低芯片供应的总成本。从回归分析来看，削片机的发动机功率很好地表达了削片和运输成本，并通过日本岩手县的供应链模型验证了这些成本之间的权衡关系。中型发动机的削片机，发动机功率200-400kW，从经济和交通管理的角度来看是最好的选择，而业务规模需要至少20,000实m3年−1。发动机较小的削片机的总供应成本并不是最好的，但可以推荐吸引产量在10,000实m3年−1以下的小公司。如果业务规模在50,000实m3年−1左右，可以引入发动机更大的削片机。但是，即使可以降低削片成本，供应链也会需要更大的卡车或拖车来实现如此大的业务规模。穿梭运输系统需要改进，以减少占周期时间五分之一到四分之一的卸货时间和空车。
The best chipper engine size was obtained by optimising the chipping operation according to business scale and transportation cost. The total chip supply cost could be reduced by improving the rate of machine utilisation of chippers. From regression analysis, the engine power of chippers expressed well the chipping and transportation costs, and the trade-off relationship between these costs was proved by the model supply chain in Iwate Prefecture, Japan. The chipper with a middle-sized engine, with an engine power of 200–400 kW, was the best choice in the perspective of economy and transportation management while the business scale needed to be at least 20,000 solid m3year−1. The total supply cost by a chipper with a smaller engine was not the best but it could be recommended to attract small-scale companies that produce less than 10,000 solid m3year−1. Chippers with a larger engine could be introduced if the business scale was about 50,000 solid m3year−1. However, even if the chipping cost could be reduced, the supply chain would require larger trucks or trailers on such a large business scale. The shuttle transportation system needs to be improved to reduce the unloading time that occupies one-fifth to one-fourth of a cycle time and empty drives.
