%X Time-lag problem means that the system states are affected by both current states and past states. The qualitative simulation of the fixed time-lag problem is discussed in this article. Discretization of the problem is analyzed, which makes it possible for us to consider the problem on discrete time points. Based on the Q2 algorithm, past constraints are added to represent the latency. By propagating quantitative information in the system with past constraints and current constraints, qualitative simulation of fixed time-lag system can be realized.
