摘要

Several hundred billion dollars are spent annually in the United States alone inspecting and maintaining engineered systems. A new business trend being established shifts to the manufacturer the responsibility for its products, extending throughout the products' life including operation, maintenance and, if applicable, disposal and recycling. Although attempts are now underway to develop technologies that seek to optimize the scheduling of resources, there exists no method or tools that optimize all relevant aspects of the integration of remote inspection and health management technologies into engineered systems. Specific and proprietary point-solutions have been developed to address individual aspects of the problem but are not in general applicable to other systems. This paper addresses the initial stages of a multidisciplinary research program focused on the system-level issues that need to be addressed in order to bring remote inspection, diagnostics and prognostics to practice. The commercial deployment of such technology in the short term faces important challenges such as: 1. The lack of methodologies to deal with complex mixed-field models; 2. Resistance to add sensors and use only sensors needed for product operation; 3. High cost, low battery-life, low reliability sensors and communication network; 4. Lack of reliable diagnostic and prognostic algorithms; and 5. Lack of design and simulation tools to allow optimization of design candidates. These technological barriers must be overcome if the desired changes in the way engineered systems are designed and maintained are to materialize. When these barriers are overcome, widespread acceptance and availability of remote inspection and health management of engineered systems will quickly follow. The impact would be felt in new safety codes, warranty and maintenance policies, and lower cost of products, as well as cost of inspection and maintenance, spanning a wide spectrum of applications.
