    • A method for increasing the execution speed of a cost-minimizing routing algorithm, as employed in trucking or job shop scheduling. Penalty functions for succeeding transit points along a route are added and examined for validity during trial route evaluation. A soft time window is set for each transit point, and proposed routes are evaluated using a total cost including all soft time windows along the route and the length of the route. A static soft time window function and a dynamic soft time window function are correlated with each transit point. The dynamic soft time window function for each transit point is the sum of the static soft time window function for the Transit point and the dynamic soft time window function for a succeeding transit point in the direction of travel.
    • 一种用于提高成本最小化路由算法的执行速度的方法,如在货车运输或作业车间调度中所使用的。 在路线评估过程中,添加并检查路线中后续过境点的处罚情况。 为每个过境点设置一个软时间窗口,并且使用总成本来评估所提出的路线,包括沿路线的所有软时间窗口和路线的长度。 静态软时间窗函数和动态软时窗函数与每个转接点相关。 每个过境点的动态软时间窗函数是运输点的静态软时间窗函数与运行方向上后续中转点的动态软时窗函数之和。
