中心型甩挂运输是指以单车场为集疏中心的一拖一挂甩挂，其车辆调度则是指各任务之间的牵引车调度。文中综合考虑牵引车空驶、带空挂车行驶和带重挂车行驶所引起的不同成本，定义了牵引车运行成本的概念，并将其作为调度方案优劣的判别指标。将牵引任务分为四种类型，定义了任务链、虚拟任务、链内交叉和链间交叉的概念，提出了一种求解该类车辆调度无时间窗约束的启发式算法，包括空车调运、初始调运方案、链内交叉、空车调运交叉、牵引车数量检验和链间交叉。最后给出了仿真算例，所计算的最终方案效果明显好于初始方案，验证了算法的有效性和可行性。

Tractor and trailer transport of center-type depot refers to a single-depot center of tractors and trailers,and the scheduling problem means assigning tractors among tasks,including empty trailers and loaded trailers.Based on the different consumption of a tractor under travelling alone,with an empty trailer or a loaded trailer,travelling cost was defined to evaluate all kinds of scheduling proposals.Pulling tasks were classified into four types.Under the definition of task chain,virtual task,inter-chain crossover and intra-chain crossover,we proposed a heuristic algorithm to solve this kind of scheduling problem without time windows,including empty trailer scheduling,initial proposal,inter-chain crossover,empty trailer crossover,tractor quantity verification and intra-chain crossover.In the simulating instance given in this paper,the final proposal was absolutely better than the initial one,which verifying the effectiveness and feasibility of the algorithm.
