Pade approximation for stochastic discrete event systems

It is shown that Pade approximation can be used effectively for the approximation of performance functions in discrete event systems. The steps of the method are: (1) obtain the MacLaurin coefficients of the performance function, and (2) find a Pade approximant from the MacLaurin coefficients and use it to approximate the function. The method is used with GI/G/1/1 systems, GI/G/1 systems, and inventory systems. The results are satisfactory.<
