Enterprise resources are the combination of entities concerned with engineering, management, system integration, etc. Reusability and interoperability of resources are the inherent requirement of enterprise operation. Engineering design is such a case which involves various resources such as tools, models and teams. To construct an environment for collaborative design, we employ web services as the infrastructure for resource wrapping and communication. At the same time, HLA is introduced towards simulation management in design analysis. Thus, simulation is leveraged through remote access of its components and web services are controlled in such a simulation oriented solution. The collaborative simulation of tilting locomotive is studied to verify the feasibility of employing web services. The results confirm that web services and SOA are promising for a new computing paradigm in modern enterprises.
