在未来几年中，爱尔兰将继续面临对木材生物质作为可再生能源的日益增长的需求。这将导致紧张的供应/需求情况，这将需要新的规划和物流系统，能够优化生物质资源的有效利用。在这项研究中，开发了一种线性规划工具，其中包括水分含量（MC）作为两个供应链的成本优化的驱动因素，使用短木材和整棵树从间伐作为材料原料。该工具的设计和实施旨在分析含水量和卡车配置（5轴和6轴卡车）对供应链成本和供应材料空间分布的影响。结果表明，包括从整个树木的木片降低了木材能源供应的成本相比，只生产木片从短木材，以满足需求，与9.8%和10.2%的成本降低时，分别与5轴和6轴卡车运输。限制运送到发电厂的木屑的MC增加了运输和整体供应链成本，这首先是由于运输距离的增加，其次是由于提供生物质材料的县的数量。在卡车配置方面，与分析的MC情景中使用5轴卡车相比，使用6轴卡车导致卡车数量减少14.8%，运输成本减少12.3%。
In the coming years, Ireland will continue to face an increasing demand for wood biomass as a renewable source of energy. This will result in strained supply/demand scenarios, which will call for new planning and logistics systems capable of optimizing the efficient use of the biomass resources. In this study, a linear programming tool was developed which includes moisture content (MC) as a driving factor for the cost optimisation of two supply chains that use short wood and whole trees from thinnings as material feedstock. The tool was designed and implemented to analyse the impact of moisture content and truck configurations (5-axle and 6-axle trucks) on supply chain costs and spatial distribution of the supply materials. The results indicate that the inclusion of wood chips from whole trees reduces the costs of wood energy supply in comparison with only producing wood chips from short wood to satisfy the demand, with 9.8% and 10.2% cost reduction when transported with 5-axle and 6-axle trucks, respectively. Constraining the MC of the wood chips delivered to the power plant increases both transport and overall supply chain costs, due, firstly to an increase in the haulage distance and secondly, to the number of counties providing the biomass material. In terms of truck configuration, the use of 6-axle trucks resulted in a 14.8% reduction in the number of truckloads and a 12.3% reduction in haulage costs in comparison to the use of 5-axle trucks across the MC scenarios analysed.
