Kronecker Modeling and Analysis of Multidimensional Markovian Systems

This work considers Kronecker-based models with finite as well as countably infinite state spaces for multidimensional Markovian systems by paying particular attention to those whose reachable state spaces are smaller than their product state spaces. Nume

Preface

This book is about the Markovian modeling and analysis of systems with a discrete multidimensional state space in which various transitions take place. The models of interest are composed of submodels, each dimension corresponds to a submodel that represents a different subsystem, and submodels interact through possible transitions. Particular emphasis is on multidimensional models having unreachable states that appear in the product state space of submodels but can never be occupied in practice. The book shows step-by-step how the transition matrix of the model associated with the reachable state space can be represented compactly and exactly on computer using sums of Kronecker products of matrices associated with submodels. Then the analysis amounts to the numerical computation of steady-state or transient solutions of very large such
