摘　　要：在工程注册类执业考试中,几乎每年都考项目进度网络图的关键线路查找、确定关键工作或时间参数的计算,而此类题目有时占分值比例较大。如采用传统的图上计算法、节点法、破圈法、标号法等计算法,计算过程繁锁、复杂,容易出现计算错误,白白浪费了此类题目的时间和分值,有时还会将考生绕晕,不利于发挥。比如建造师、造价工程师等考试实务中,对它掌握的情况好坏,决定了考试的是否能通过。因此,采用极速简便的计算方法,尤为重要。现介绍一种思路清晰,方法极其简便、计算精准且快速的方法:秒杀法。To find Project Schedule Network diagram of the critical path and to determine the calculation of critical work or time parameters are tested almost every year in the engineering registration practice examination,and sometimes such topics account for a large proportion of the score.The calculation process of using traditional graph method,such as node method,broken ring method,marking method and other methods of calculation is cumbersome,complex,and prone to miscal-culation,and wastes time and score of such topics.Sometimes the candidate will be dizzy,not conducive to play.For instance,the certificate constructor and cost engineer examination require the knowledge of network scheduling.And the mastery of network scheduling determines the re-sults of these examinations.Therefore,it is particularly important to use the extremely fast and simple calculation method.Now,we introduce a clear-minded,extremely simple,accurate and fast method:Calculation in Seconds.
