摘要
传统的网络技术规定工序可以在任意时刻开始,但是在现实的工程中由于时间转换约束的存在,活动很少在满足优先关系约束后在任意时刻开始.本文主要是在时间转换约束模型网络的基础上,提出时间转换约束对网络关键线路的影响,并对网络的传递性进行了分析,得出传递量推算过程.最后通过算例验证了其准确性.
Traditional network technology assumes that activities can begin at any time. Due to the time-switch constraints, however, it is impossible for activities to start at any time satisfying the precedence relations. Based on the activity network model with time-switch constraints, the impact of the time-switch constraints on the critical path is presented. This paper analyzes the network transitivity, and then proposes the calculation procedure of transmission capacity. Finally, feasibility and validity of the conclusion are illuminated by an example.
