Abstract	The paper presents techniques that enable the modeling and analysis of redundancy schemes in distributed object-oriented systems. The replication manager, as a core part of the redundancy scheme, is modeled by using UML statecharts. The flexibility of the statechart-based modeling, which includes event processing and state hierarchy, enables an easy and efficient modeling of replication strategies as well as repair and recovery policies. The statechart is transformed to a Petri-net based dependability model, which also incorporates the models of the replicated objects. By the analysis of the Petri-net model the designer can obtain reliability and availability measures that can be used in the early phases of the design to compare alternatives and find dependability bottlenecks. Our approach is illustrated by an example.
