Paper Abstract

A Markov chain model is studied and evaluated in determining the retrieval rates of an analog film library and an electronic grayscale display system in an image management network (PACS). This model provides a reasonable representation of retrieval rates since Markov chains depend only upon the current and previous state of the chain. The model requires identification of the states of the chain, one-step transition probabilities between the states, and the initial probabilities of occurrence of the states. The use of the model is demonstrated with three examples. The results of the model are in agreement with measured data.
