An efficient discrete-event model for production networks of general geometry

A discrete-event hybrid simulation/analytic model for the study of production networks is discussed. The system is represented by a set of nonlinear difference equations for the slow-varying dynamics which are tractable by simulation, and a set of piecewise-linear algebraic equations for the fast dynamics which are solved analytically. The resulting algorithm saves a great amount of computation and is much faster than a conventional piece-by-piece simulator.<
