light bulb

Consider a light bulb whose life, measured in discrete units, is a random variable X where Pr[X = k] = pk for k = 1, 2, .... If one starts with a fresh bulb and if each bulb is replaced by a new one when it burns out then un, the expected number of replacements up to time n, solves the equation

 

In a large building it is often cheaper, on a per bulb basis, to replace all the bulbs, failed or not, than it is to replace a single bulb, due to economies of scale. A " block replacement policy " is a function of the block period N and calls for replacing bulbs as they fail during periods 0, 1, ..., N— 1, and then replacing all bulbs, failed or not, in period N. If C1 is the per bulb block replacement cost
