为了从经济、环境和社会3个维度优化黑龙江木材供应链结构,围绕黑龙江省木材供应链的新特点,利用加权多目标决策方法,对有4个节点、3阶段物流、2级库存的木材供应链进行优化研究.结果表明,经济、环境、社会3个目标无法同时最优,单一目标最优时其余目标结果较差,找到3个目标的次优解恰恰是同时满足3个目标的最佳方案的圈(见文章C圈).当经济成本从最低上升1.0％时,环境效益增幅从0.10％上升到1.55％,社会效益增幅从1.80％下降到0.55％,企业可根据自身发展阶段,选择适当决策方案.因此,该模型可以作为木材企业优化供应链结构的决策支持工具,可帮助木材企业经营者提供在经济、环境和社会绩效方面最符合企业战略目标的决策.

In order to solve the problem of the optimization of delivery and pickup cargoes' routes with time windows under the constraints of load and road, the method and algorithm were designed and researched based on these factors. Firstly, the model was built with the constraints of truck number, load quality, load capacity, maximum distance, and customer service time in order to minimize the transportation cost and time cost. Then, the Floyd Algorithm was used to determine the moving path and the shortest distance between each point with the road constraint. 0-1 integer programming method was used to determine the number and type of vehicles. Tabu search algorithm was used to determine the order of delivery and pickup points and the distribution route based on the influence of job requirements of pickup cargoes, the time cost, and the transportation cost. Finally, the case was given to verify the effectiveness of the proposed method. This method can be used to improve the efficiency of delivery and pickup cargoes and the level of distribution service.

本文的目的是解决车载约束与道路约束下带时间窗的揽送货物线路优化问题.以往研究配送路线缺乏对揽收货物作业和车载约束的考虑,本文基于相关影响因素基础上进行了方法研究与算法设计.首先建立了以运输费用和时间成本最小为目标,以车辆数、载重量、载货容量、最大行驶距离与客户服务时间为约束的多目标优化决策模型,再利用弗洛伊德算法结合道路约束,确定各点间的最短行驶距离与行驶路径,利用0-1整数规划方法确定货车数与规格,最后利用禁忌算法根据揽收货物作业要求、时间成本与运输成本的影响,得到揽货信息影响下的揽送顺序与配送路径,并用实例验证了该方法的有效性.通过该方法可以提升配送中心的揽送货物作业效率,提高配送服务水平.

Wild forest fruit supply chain is complex and has high risk.In order to reduce the risk and improve the circulation efficiency and forest products trade level,this paper analyzed wild forest fruit supply chain risk relationship based on system dynamics theory,and simulated the effects of risk control measures.Wild forest fruit supply chain was systematically analyzed and risk causal relationship diagram was constructed by exploring the causes of risk.The dynamic model of risk management system was built based on risk,factors of risk,risk control objects and overall system risk.Then,Vensim was used to simulate the model.Results showed that increasing the risk control input ratio coefficient βi could reduce the overall risk and the overall risk reduction was different.Research suggested that risk control could reduce the overall system risk.Among them,the promotion of product custody level than other measures could significantly reduce the overall system risk.Therefore,this paper put forward the reasonable countermeasures of risk control,which aimed to provide reference for the further study of forest product supply chain risk control.
