| Abstract: | Large Movie-On-Demand (MOD) and Video-On-Demand (VOD) systems need to offer a set of popular movies on-line. Given the changing movie popularity and daily load fluctuations, however, it is still not a trivial task to maintain an optimal set of movies from a diverse archive. Replication of the most popular movies across multiple storage devices is also needed to increase the bandwidth of these movies in meeting their high demand. However, selection and replication of movies can only be varied within the constraints imposed by the on-line storage space and organization. In this dissertation study, I evaluate three movie-demand models based on which strategic decisions on selection and replication can be exercised. The long-term Static Movie-Demand (SMD) model is a quantized version of a trivial approach. The bounded-SMD (B-SMID) model is an improved version of SMD with bounded movie lifespan. In this dissertation study, I propose a new model called the Trend-Calibrated Movie-Demand (TCMD) model. Through simulation studies I have found that movie selection and replication based on TCMD can significantly improve the percentage of customer requests satisfied. |
