Abstract
We consider the quickest time detection problem with risk-sensitive costs. First, the detection of a change point with a geometric distribution is analyzed and a threshold policy is obtained. Next, we establish a consistency relationship between the risk-sensitive detection and the detection based on risk-neural costs. Furthermore, we generalize the method to change point with a phase type distribution which may be used to approximate change point with an arbitrary distribution. Numerical examples are also given.
