Abstract : This thesis utilizes data on the time to failure of individual light valves to represent the random process of all failures at a many-valve training unit. This process governs the demand for replacement spares. The light valve replacement model, with finite spares, is based on theoretical results concerning the Poisson tendency for a superposition of renewal processes. Graphical analysis and a simulation verify that the theory can apply under practical circumstances. The model is distinguished by its applicability for use in standard spreadsheets; no specialized statistical features are required.
