摘要： A system software solution for controlling an enterprise which defines and illustrates the electrical, pneumatic, hydraulic, logic, diagnostics, external behavior, controlled resources and safety elements of an enterprise control system. The elements of the control system are encapsulated in objects of an object-oriented framework within a control assembly. The control assembly is the fundamental building block for providing object-oriented control of the enterprise. A control assembly component is a deployable control subsystem that provides an interface using a common object model that is configurable. The enterprise control system includes facilities for retrieving external models utilizing a predefined interface. The retrieved model includes support for external resources such as an external resource tree in which the leaf nodes correspond to resources to be controlled, resource and process information and a computer aided design model. The retrieved model is transformed from a flowchart representation into a timing diagram.

摘要： A method and system for allocating programming objects of a control program configured to control a distributed control system having a plurality of distributed control modules. A graph model of the distributed control system is constructed which represents all the possible allocations of the control program's virtual programming objects to the processing resources associated with the system's control modules. A maximum matching algorithm is applied to the graph model to determine an optimum allocation, which, for instance, may be the allocation that provides the maximum benefit. The system and method also provide for intervention by the user to refine or "tune" the allocation process. Further, the system and method provide for iteratively solving the graph matching problem, thus reducing the computation time for allocating the programming objects of a complex distributed control system
