โœฆ Synopsis

Traditional system dynamics models are subject to error in the estimation of performance measures because of the method of calculation over discrete time intervals. It is shown that such errors may be signiยฎcantly reduced by dividing the computation between two runs with dierent solution intervals and applying Richardson's extrapolation method. Examples are given for a variety of dierent published models and performance measures.

The subject of this paper is the asymptotic behavior of a class of nonautonomous, infinite-dimensional dynamical systems with an underlying unbounded domain. We present an approach that is able to overcome both the law of compactness of the trajectories and the continuity of the spectrum of the line

The Markov analysis of reliability models frequently involves a partitioning of the state space into two or more subsets, each corresponding to a given degree of functionality of the system. A common partitioning is G U B U { W ) , where G (good) and B (bad) stand, respectively, for fully and partia
