Abstract
A generic service management system is disclosed. The generic service management system comprises a registration scheme; a search-and-execution scheme; and a detection-and-replacement scheme, used for detecting and replacing the invalid service provider, such as a semiconductor equipment manager. The present invention provides a GEV (Generic Evaluator) having the capabilities of error-detecting and data backup, and further combines Jini infrastructure and the programming technology of design by contract. The GEV archives the credit values of all the service providers for letting a client (such as a factory manager) to select a service provider having a higher credit value. The GEV periodically backups the execution status and parameters of service providers, so that, in case a service provider has errors, its backup information of execution status and parameters can be assigned to another service provider for continuously executing the unfinished job, thereby enhancing the reliability of distributed object-oriented systems. The present invention can detect abnormal behaviors, such as system crash, errors in transmitting information and degradation of performance, etc., and is suitable for use in production systems that are connected by networks, such as semiconductor manufacturing systems, optical telecommunication production systems, etc.
