Technical content of postal services has been increased with the remarkable improvement of mechanization for mail processing and computerization of counter operations. 郵政科技含量不斷增加，郵政作業處理機械化和營業窗口電子化的水平明顯提高。
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. 同時為了減少計算誤差，該算法計算時不需要將模糊時間轉換為精確時間求解，可以同時處理作業加工時間是三角模糊數或梯形模糊數的情況，從而更具有通用性。
