摘要：

The stochastic model presented in this paper is a random differential equation of the form X(t) = AX(t) + Y(t), t ≥ 0, with initial conditionsXo = X(0).X(t) is a vector with biochemical oxygen demand (BOD) and dissolved oxygen (DO) at a distance t downstream from the pollution source for components. The velocity of the stream is incorporated into the A vector and is considered a random variable. Also the initial conditions are considered random. Therefore, this model contains random initial conditions and random coefficients. Simulated trajectories of the BOD and DO processes are computed and some of their statistical properties are discussed. © 1979, Taylor & Francis Group, LLC. All rights reserved.
