Virtual maintenance is a new method of maintenance technology, which has deficiencies in disassembly planning, especially in the constraint of ergonomics factors and the hierarchical division of the components. On the basis of Petri net, the interpretative structural model is introduced to divide the equipment components and simplify the description of the maintenance disassembly process. In order...
Studying on river shoal evolution is a fundamental work in the science of water conservancy, water conservancy projects and waterways planning, designing, engineering feasiblility. First of all, the neural network model for predicting the evolution of shoal in a river is established, through training the neural network to determine the number of hidden layer's neural, thus, a more ration neural network...
