ABSTRACT Today, timber trucks of gross vehicle weight (GVW) up to 76 tonnes are allowed to operate on Finnish roads from roadside landings to mills. Reducing trucking costs and exhaust gas emissions have been the dominant reasons for the increased GVWs of timber trucks. A discrete-event simulation (DES) method was used to compare the impact of the truck and payload size, trucking distance, and timber assortment lengths on trucking performance indicators (e.g., productivity, energy efficiency, and costs of trucking) in the procurement area of a case logistic company operating in Central Finland. The studied truck sizes were 68, 76 and 84 t, of which the 76-t trucks dominate timber trucking in Finland. Over a transport distance of approx. 105 km with an average assortment length of 4.2 m, 76-t trucks had 9% higher and 12% lower productivity (m3/100 km), 1% lower and 4% higher fuel consumption (l/m3) and 4% lower and 6% higher trucking cost (€/m3) compared to 68- and 84-tonner options, respectively. The improvement in regards to previous indicators was clearly bigger for the 76-tonner than the 68-tonner if the trucked wood assortments were lengthened to 5.0 m. The differences in cost and fuel efficiency as well as annual trucking volumes were increased as a function of the trucking distance, when comparing the truck configurations with different GVWs and payloads. To conclude, the tendency of the size increase in GVWs in timber trucking in Finland can be justified in light of the study results.

车辆总重 (GVW) 和运输距离对木材卡车运输性能指标的影响——芬兰中部的离散事件模拟案例研究

摘要 今天,从路边着陆到工厂的芬兰道路上允许车辆总重 (GVW) 不超过 76 吨的木材卡车。降低卡车运输成本和废气排放是木材卡车 GVW 增加的主要原因。使用离散事件模拟 (DES) 方法来比较卡车和有效载荷大小、卡车运输距离和木材分类长度对采购区域的卡车运输性能指标(例如生产率、能源效率和卡车运输成本)的影响一家在芬兰中部运营的案例物流公司。研究的卡车尺寸为 68、76 和 84 吨,其中 76 吨卡车在芬兰的木材卡车运输中占主导地位。在大约的运输距离。105 公里,平均分类长度为 4.2 m,76 吨卡车的生产率(立方米/100 公里)提高 9% 和降低 12%,燃料消耗(升/立方米)降低 1% 和提高 4%,卡车运输成本(欧元/立方米)降低 4% 和提高 6%分别为 68 吨和 84 吨选项。如果卡车运输的木材品种加长到 5.0 m,则 76 吨车在先前指标方面的改进明显大于 68 吨车。在比较具有不同 GVW 和有效载荷的卡车配置时,成本和燃料效率以及年度卡车运输量的差异随着卡车运输距离的增加而增加。总而言之,根据研究结果,可以证明芬兰木材卡车运输中 GVW 规模增加的趋势是合理的。分别。如果卡车运输的木材品种加长到 5.0 m,则 76 吨车在先前指标方面的改进明显大于 68 吨车。在比较具有不同 GVW 和有效载荷的卡车配置时,成本和燃料效率以及年度卡车运输量的差异随着卡车运输距离的增加而增加。总而言之,根据研究结果,可以证明芬兰木材卡车运输中 GVW 规模增加的趋势是合理的。分别。如果卡车运输的木材分类加长到 5.0 m,则 76 吨车在先前指标方面的改进明显大于 68 吨车。在比较具有不同 GVW 和有效载荷的卡车配置时,成本和燃料效率以及年度卡车运输量的差异随着卡车运输距离的增加而增加。总而言之,根据研究结果,可以证明芬兰木材卡车运输中 GVW 规模增加的趋势是合理的。在比较具有不同 GVW 和有效载荷的卡车配置时。总而言之,根据研究结果,可以证明芬兰木材卡车运输中 GVW 规模增加的趋势是合理的。在比较具有不同 GVW 和有效载荷的卡车配置时。总而言之,根据研究结果,可以证明芬兰木材卡车运输中 GVW 规模增加的趋势是合理的。
