Error Specification, Monitoring and Recovery in Computer Integrated Manufacturing: An Analytic Approach
نویسندگان
چکیده
State transitions in Computer Integrated Manufacturing Systems result either from the execution of the planned actions or from the occurrence of unpredictable events. One key requirement for task planning designed for CIM systems, is the ability to monitor events and respond to them appropriately. Related issues include the specification and classification of possible system faults, errors and failures. This paper proposes an error specification language, an error monitoring mechanism (EMM) and an error recovery mechanism (ERM). Founded on a mathematical framework, the error recovery mechanism uses the concept of severity to alter system characteristics. The paper concludes with a presentation of some examples from an integrated multi-robot system.
