    PHM has the potential to drive future warranty strategies for companies to increase their competitive advantage. PHM methods are able to prevent a system from degrading by isolating it from inappropriate conditions or failing parts. PHM will permit companies to offer longer warranties at lower prices, which can further enable lifetime warranties in industry. Availability-based warranties can be im... View full abstract»

    Safety and maintenance of building structures have become a prime concern as there are millions of buildings in China. Lifts and pipes are crucial infrastructure integrated in most of building. Ropes are used to hoist or support lifts. Pipes are used to transfer water or gas to each household unit of a building. In modern cities, natural gas is a major fuel source for heating and cooking. Gas pipe... View full abstract»

    The study of the changing trends of the performance of the spacecraft is helpful to the estimation of the remaining usage life (RUL), which is the important basis of the realization of the spacecraft prognostics and health management. The types of the spacecraft telemetry data include the slow change, periodic change, abrupt change and the combination of the above three changes. This paper firstly... View full abstract»

    Based on analyzing the cosmonaut operations in spaceflight, the concept of “metaoperation” and the method of establishing the “metaoperation” set are put forward by means of the human reliability theory. Found on PMS(Phased Mission System) and HCR(Human Cognition Reliability) model, the model framework of human reliability for complicated spaceflight mission is set up. View full abstract»

    In the environment of system-of-systems combat, a new data fusion method based on mutual rangings between missiles for multi-missile cooperative localization (MCL) is proposed to improve the inertial positioning accuracy of the missile community. The cooperative localization data fusion system, which is mainly composed of the missile-borne data link and inertial navigation system (INS), was design... View full abstract»

  • A novel fault diagnosis method for satellite systems based on multivalue logic inference with semi-tensor product of matrices

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (375 KB) | HTML iconHTML

    Due to complexities in satellite systems, the relationship between faults and symptoms become more complex, usually each fault may be related to several fault symptoms and some different faults can result in the same symptoms, so as to make the fault diagnosis very hard with direct symptom analysis. Some suspected faults could be found through symptom analysis combined with a priori knowledge, how... View full abstract»

    In the application of lifetime prediction, sometimes the degradation parameter would be disturbed due to the unstable environment. This phenomenon is negative to the prediction of the lifetime and reliability. So we take Super-luminescent Diode (SLD) as an example, to research the method of degradation parameter pre-processing method under the temperature stress. Firstly, analyze the relationship ...

    To avoid the errors caused by pseudo life prediction in degradation testing, this paper proposes a reliability prediction method based on degradation measure distribution and wavelet neural network. The style of degradation measure distribution is assumed to be unchangeable during degradation procedure, while the character parameters, such as location and scale parameters, are time-dependent covar...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1113 KB) | HTML iconHTML

    Fault prognosis plays a key role in prognostics and health management (PHM). Currently, there are many methods to predict the occurrence of a fault, but the fuzzy model has become an effective alternative owing to its advantage of using not only quantitative data but also qualitative information with fuzzy uncertainty. It is particularly useful for a dynamic system with complexity, morbidity and n... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (917 KB) | HTML iconHTML

    This paper proposes a model to predict the residual useful life of a component by condition monitoring. An adaptive gamma process is used to describe the deteriorating nature of the observed condition indicator but one of the parameters of the gamma model is updated whenever a new observation of the indicator becomes available. The updating is performed by means of a state space model where the pa... View full abstract»
