摘要:
由于应用广泛,随机活动网络近年来得到了深入的研究。文献中研究的分布函数主要是指数分布、Erlang及Weibull分布函数。本文研究的活动持续函数为位相分布的随机活动网络,并给出了估计该网络工程竣工时间的的矩方法。

Abstract:
Stochastic activity networks have been studied extensively in thepast several decades, due to their vast applications in a variety offields. Many distribution functions have been considered in theliterature to model activity durations such as exponential, Erlangand Weibull. This paper deals with stochastic activity networkswhose activity durations are independent random variables withphase-type distributions. A moments method for estimating theproject completion time of the above networks is presented.
