In this paper, the intermittent fault detection and location problems are considered for stochastic multi-agent systems with time delay. Based on the lifting method and parity space technique, the truncated residuals are proposed by using the available measurement outputs of each agent. In addition, by using the hypothesis testing method, the thresholds are determined by analyzing the stochastic characteristics of the residuals. At last, the effectiveness and practicability of the presented scheme are validated via a simulation.
