Technical content of postal services has been increased with the remarkable improvement of mechanization for mail processing and computerization of counter operations. 邮政科技含量不断增加，邮政作业处理机械化和营业窗口电子化的水平明显提高。
The algorithm can deal with the situation in which job processing time is triangle fuzzy number and trapezoid fuzzy number, so that the common ability is strengthened. 同时为了减少计算误差，该算法计算时不需要将模糊时间转换为精确时间求解，可以同时处理作业加工时间是三角模糊数或梯形模糊数的情况，从而更具有通用性。
