The Resource Conflicts Detecting Method of Virtual Manufacturing Cell Based on Bayesian Network

Resource conflicts have new characteristics under the condition of virtual manufacturing cell. The existing model tools have a shortage in solving the resource conflict detection of virtual cell. So this paper puts forward a new method of resource conflicts detection on virtual manufacturing cell. According to the resource plan of productive task, Bayesian network model of virtual manufacturing cell was established. We raised the model of resource conflicts occurring on the basis of the Bayesian network. We detected the position and quantity of the resource conflicts in the Bayesian network in accordance with the model of resource conflicts occurring. Then we used an example to verify this method. The results show that this method is feasible and effective. The method lays the foundation of the specific resolution of the resource conflicts on virtual cell.

The Impact

Islands are one of the most sensitive interfaces between global changes and land and sea dynamic effects, with high sensitivity and low stability. Therefore, under the dynamic coupling effect of human activities and frequent natural disasters, the vulnerability of the ecological environment of islands shows the characteristics of complexity and diversity. For the protection of island ecosystems, a system for the assessment of island ecosystems and studies on the mechanism of island ecological vulnerability are highly crucial. In this study, the North and South Changshan Islands of China were selected as the study area. Considering various impact factors of island ecological vulnerability, the geographical information systems (GIS) spatial analysis, field surveys, data sampling were used to evaluate island ecological vulnerability. The Bayesian network model was used to explore the impact mechanism of ecological vulnerability. The results showed that the ecological vulnerability of the North Changshan Island is higher than that of the South Changshan Island. Among all the indicators, the proportion of net primary productivity (NPP) and the steep slope has the strongest correlation with ecological vulnerability. This study can be used as references in the relevant departments to formulate management policies and promote the sustainable development of islands and their surrounding waters

Fault Diagnosis System

The rotor is one of the most core components of the rotating machinery and its working states directly influence the working states of the whole rotating machinery. There exists much uncertainty in the field of fault diagnosis in the rotor system. This paper analyses the familiar faults of the rotor system and the corresponding faulty symptoms, then establishes the rotor’s Bayesian network model based on above information. A fault diagnosis system based on the Bayesian network model is developed. Using this model, the conditional probability of the fault happening is computed when the observation of the rotor is presented. Thus, the fault reason can be determined by these probabilities. The diagnosis system developed is used to diagnose the actual three faults of the rotor of the rotating machinery and the results prove the efficiency of the method proposed.
