A pattern-based framework architecture for distributed engineering applications

This thesis presents the overall architecture and design of the VADOR application framework. The purpose of the VADOR framework is to enable the seamless integration of commercial and in-house analysis applications in a heterogeneous, distributed computing environment, and to allow the deployment of automatic design optimization algorithms based on the framework. VADOR is being developed in close collaboration with Bombardier Aerospace, who provides actual analysis applications, design processes in need of automation and test ground for the framework.; A multi-tiered client-server architecture has been proposed for the framework, which comprises a client GUI for interactive data definition and execution launching, separate data and execution servers, and autonomous remotely executable application wrappers. This thesis mainly focuses on the global framework architecture, introduces the client GUI, data and execution servers, the common underlying object model, and presents detailed discussions of the Design Pattern used in the Vador Framework.; Both analysis data and optimization algorithms are encapsulated in an object layer managed at the framework level. Among the services provided by this objects layer, ownership control, versioning and sharing of all framework components are among the most significant for a large corporation such as Bombardier.
