摘要：How to understand the dynamical consensus patterns in network systems is of particular significance in both theories and applications.In this paper, we are interested in investigating the influences of distributed processing delay on the consensus patterns in a network model. In results, some criterions of weak consensus and periodic consensus with exponential convergent rate are established by the standard functional differential equations analysis. An analytic formula is given to calculate the asymptotic periodic consensus in terms of model parameters and the initial time interval. Also, we post the threshold values for some typical distributions included uniform distribution and Gamma distribution.
