Availability analysis of composite coteries

A collection of quorums is called a coterie. The authors present an algorithm to construct coteries by composing existing coteries. The resulting coteries are called composite coteries. Several different measures may be used to analyze coteries. One of the most commonly used measures is availability. In general, it is difficult to directly compute the availability of coteries in a large system. An efficient method is described to compute the availability of composite coteries, even in a large system.<>
