Abstract

Methods and reconfigurable systems are provided for monitoring the health of a complex system. The reconfigurable system comprises a plurality of standardized executable application modules containing instructions to perform one of a plurality of different standardized functions. The system further comprises a plurality of computing nodes arranged in a hierarchical structure comprising one or more layers of computing nodes. Each computing node of the plurality runs a host application and a workflow service module, each computing node thereby being configured by a configuration file that directs the execution of any of the standardized executable application modules in a cooperative fashion by the host application via the workflow service module. The system also comprises a loading means for populating each computing node with one or more standardized executable application modules of the plurality, a communication means, and a configuration means for programming the populated standardized executable application modules.

11. The reconfigurable system of claim 10, wherein the communication interface comprises a customized adapter.

12. The reconfigurable system of claim 10, wherein each workflow service module directs intra-nodal communication between directed SEAM and between a directed SEAM and another node via the communication interface.

13. The reconfigurable system of claim 1, each loaded configuration file activates and deactivates any of the directed SEAM residing in any of the computing nodes of the plurality of computing nodes.

14. The reconfigurable system of claim 1, wherein the loaded configuration files control a relocation of any specific functionality residing in one computing node to another computing node.

15. A method for configuring a system monitoring the health of a complex system, comprising:

establishing a plurality of computing nodes arranged in a hierarchical structure that comprises at least two layers of computing nodes, each computing node is associated with a component of the complex system;

establishing a library containing a plurality of standardized executable applications (SEAMS), wherein a SEAM is a basic un-modifiable modular software object that is directed to complete specific tasks after being configured by a configuration file;

establishing one or more configuration files within a database, each configuration file is associated with one of the plurality of computing nodes of the hierarchical structure;
