【摘要】：在木材供应链中,木材需求量受到市场竞争环境变化影响,供应量则受到土地状况、森林经营计划等因素的影响,均呈现不确定的动态变化特征,而木材物流网络规划的周期一般较长,因此多周期模型更符合实际的生产实践。在分析木材物流网络特性的基础上,考虑不同规划期内供需状况的变化,以物流网络总成本最小为优化目标,包括木材物流中心打开成本、关闭成本、运营成本、流转成本、木材从供应点到物流中心以及从物流中心到需求点的运输成本,建立了多周期木材物流网络优化模型。将该模型应用于某林业集团的木材物流网络规划,利用Lingo 11.0进行求解。结果表明,采用多周期模型的优化结果比采用单周期模型的优化结果总成本降低了8%,从而也证明了多周期木材物流网络优化模型的合理性、可行性和有效性。
[Abstract]:In the wood supply chain, the demand for wood is affected by the market competition environment, and the supply is affected by the land condition, forest management plan and so on.The cycle of timber logistics network planning is generally long, so the multi-cycle model is more suitable for practical production practice.On the basis of analyzing the characteristics of timber logistics network, considering the change of supply and demand situation in different planning periods, taking the minimum total cost of logistics network as the optimization goal, including the opening cost, closing cost, operation cost and circulation cost of timber logistics center, the paper analyzes the characteristics of timber logistics network.Based on the transportation cost from supply point to logistics center and from logistics center to demand point, a multi-cycle timber logistics network optimization model is established.The model is applied to the timber logistics network planning of a forestry group and solved by Lingo 11.0.The results show that the total cost of the multi-period model is lower than that of the single-cycle model, which also proves the rationality, feasibility and effectiveness of the multi-cycle timber logistics network optimization model.
