求翻译：（3）工期优化方法：工期优化是通过压缩关键线路的持续时间来满足工期要求的。当项目完工日期需要提前时，必须压缩到达该时问的最长时间线路，即关键线路，压缩最长线路时，到达同一节点的其它线路的时差也相应减少是什么意思？

(3) Time Optimization: Time Optimization by compressing the duration of the critical path to meet the schedule requirements. When the project completion date in advance, you must compress the long line to ask when you arrive at the most critical line, compression of the longest line, the time differ

(3) duration: Duration optimization method is optimized by compressing the time key lines to meet deadlines. When the project completion date to early, you must compress the time line of the longest time, the critical line, the longest zip line, reach the same node of the other lines of jet lag is r

(3) duration optimization: optimization of duration is the duration of the critical path by compressing to meet the time requirements. When the project completion date in advance, and must compress the time of maximum time lines, critical path, compress when the longest line, time difference to reac

(3) time limit for a project optimization method: The time limit for a project optimization is satisfies the time limit for a project request through the compression essential line duration.When the project finishes the date needs ahead of time, the longest time line which must compress arrives this
