The very readable monograph of Cox (1962) contributed much to the popularization of renewal theory A good account of renewal theory can also be found in the texts Ross (1996) and Wolff (1989) A basic paper on renewal theory and regenerative processes is that of Smith (1958), a paper which recognized the usefulness of renewal-reward processes in the analysis of applied probability problems The book of Ross (1970) was in uential in promoting the application of renewal-reward processes The renewal-reward model has many applications in inventory, queueing and reliability The illustrative queueing example from Section 26 is taken from the paper of Yadin and Naor (1963), which initiated the study of control rules for queueing systems Example 223 is adapted from the paper of Vered and Yechiali (1979) The rst rigorous proof of L = W was given by Little (1961) under rather strong conditions; see also Jewell (1967) Under very weak conditions a samplepath proof of L = W was given by Stidham (1974) The important result that Poisson arrivals see time averages was taken for granted by earlier practitioners A rigorous proof was given in the paper of Wolff (1982) The derivation of the Laplace transform of the waiting-time distribution in the M/G/1 queue is adapted from Cohen (1982) and the relation between this transform and the generating function of the queue size comes from Haji and Newell (1971)

The notion of what is nowadays called a Markov chain was devised by the Russian mathematician AA Markov when, at the beginning of the twentieth century, he investigated the alternation of vowels and consonants in Pushkin s poem Onegin He developed a probability model in which the outcomes of successive trials are allowed to be dependent on each other such that each trial depends only on its immediate predecessor This model, being the simplest generalization of the probability model of independent trials, appeared to give an excellent description of the alternation of vowels and consonants and enabled Markov to calculate a very accurate estimate of the frequency at which consonants occur in Pushkin s poem The Markov model is no exception to the rule that simple models are often the most useful models for analysing practical problems The theory of Markov processes has applications to a wide variety of elds, including biology, computer science, engineering and operations research A Markov process allows us to model the uncertainty in many real-world systems that evolve dynamically in time The basic concepts of a Markov process are those of a state and of a state transition In speci c applications the modelling art is to nd an adequate state description such that the associated stochastic process indeed has the Markovian property that the knowledge of the present state is suf cient to predict the future stochastic behaviour of the process In this chapter we consider discrete-time Markov processes in which state transitions only occur at xed times Continuous-time Markov processes in which the state can change at any time are the subject of 4 The discrete-time Markov chain model is introduced in Section 31 In this section considerable attention is paid to the modelling aspects Most students nd the modelling more dif cult than the mathematics Section 32 deals with the n-step transition probabilities and absorption probabilities The main interest, however, is in the long-run behaviour of the Markov chain In Section 33 we discuss both the existence of an equilibrium distribution and the computation of this distribution
