摘　　要：为了在完成既定运输任务的前提下减少大型制造企业内的碳排放量,阐述了大型企业采用甩挂运输的可行性和优越性。以吨公里CO2排放量为目标函数,构建了硬时间窗约束下的考虑碳排放的大型制造企业内牵引车优化调度模型,并设计了两阶段启发式算法求解该模型。该算法首先应用扫描算法获得模型初始可行解;然后,分别采用模拟退火算法和禁忌搜索算法提高初始可行解质量;最后,将优化模型和算法运用于以湖南华菱钢铁公司实例为基础的11个算例,并进行求解。结果表明:优化调度模型及两阶段启发式求解算法是可行、有效的。本文优化调度方法具有良好的节能减排效果,同时也说明大型制造企业内牵引车的中心节点选址能有效降低甩挂运输的碳排放量。In order to reduce the carbon emissions based on the premise of specified transportation tasks in the large manufacturing enterprises,first,the account of the feasibility and superiority of adopting drop and pull transport is given out.Second,an optimization dispatching model of tractors is constructed under the constraint of hard time window,with t·km CO2 emission as the objective function.Third,a two-stage algorithm is designed for solving the optimization dispatching model.The algorithm presented applies scan algorithm to get the initial feasible solution first,then adopts the simulated annealing algorithm and tabu search algorithm respectively to improve the solution.The optimization model and the algorithm proposed are applied to the 11 data sets of Hunan Hualing Iron and Steel Company.The experimental results indicate that the optimization dispatching model and the two-stage algorithm are feasible and effective.The dispatching optimization method for tractors with carbon emission consideration proposed in this paper has a good effect on energy saving and emission reduction.It also indicates that the reasonable location of the center node of tractors in large manufacturing enterprises can effectively decrease the carbon emissions of drop and pull transportation.
