Abstract:
Incorporating web services at the device level is expected to improve many aspects of automated manufacturing systems, including scalability, reusability, reconfigurability, compatibility between equipment from different vendors, and cross-layer integration. There is much ongoing research into architectural issues and enabling technologies for service-oriented automation, but the body of knowledge surrounding service identification and optimal orchestration schemes needs improvement. In this project, the performance of a test system, consisting of conveyors with embedded web service-enabled devices, with three different orchestration schemes is evaluated. The three schemes have similar message exchange patterns, but differ in terms of the degree of involvement of a central orchestrator. The schemes are compared in terms of pallet transfer timing, and communications load. Performance is similar for the small test system, but the results predicted scalability problems for the schemes with high reliance on a central orchestrator
