Paper Abstract

This paper describes an integration strategy for plug-and- play software based on functional descriptions of the software modules. The functional descriptions identify explicitly the role of each module with respect to the overall systems. They define the critical dependencies that affect the individual modules and thus affect the behavior of the system. The specified roles, dependencies and behavioral constraints are then incorporated in a group of shared objects that are distributed over a network. These objects may be interchanged with others without disrupting the system so long as the replacements meet the interface and functional requirements. In this paper, we propose a framework for modeling the behavior of plug-and-play software modules that will be used to (1) design and predict the outcome of the integration, (2) generate the interface and functional requirements of individual modules, and (3) form a dynamic foundation for applying interchangeable software modules. I describe this strategy in the context of the development of an agile manufacturing testbed. The testbed represents a collection of production cells for machining operations, supported by a network of software modules or agents for planning, fabrication, and inspection. A process definition layer holds the functional description of the software modules. A network of distributed objects interact with one another over the Internet and comprise the plug-compatible software nodes that execute these functions. This paper will explore the technical and operational ramifications of using the functional description framework to organize and coordinate the distributed object modules.
