3016	 A Comparison of Numerical Techniques in Markov Modeling	 This paper presents several numerical methods which may be used to obtain the stationary probability vectors of Markovian models. An example of a nearly decomposable system is considered and the results obtained by the different methods examined. A post mortem reveals why standard techniques often fail to yield the correct results. Finally a means of estimating the error inherent in the decomposition of certain models is presented.
