Executive Summary

Interoperable DEVS modeling and simulation is desirable to enhance model composability and reusability with DEVS models and non-DEVS models in different languages and platforms. The barrier to such interoperability is that DEVS simulators implement the DEVS modeling formalism in diverse programming environments. Although the DEVS formalism specifies the same abstract simulator algorithm, different simulators implement the same abstract simulator in different ways. This situation inhibits interoperating DEVS simulators and prevents simulation of heterogeneous models. Service Oriented Architecture provides a flexible approach to interoperability than because it provides platform independence and employs platform-neutral message passing with Simple Object Access Protocol to communicate between a service and a client.
