Abstract: A network may be organized to provide components. Components may be generated by combining other components (sub-components) together, and components may be provided by resources in the network. This network may be represented by a graph of nodes representing components and resources. In order to efficiently analyze this graph to generate a network plan, the graph may be subdivided into independent sub-graphs. Individual resources may be shared by individual sub-graphs and considered independent when those resources are underutilized or otherwise unconstrained. Models may be used to predict which resources are unconstrained and allow those resources to be shared by otherwise independent sub-graphs, thereby increasing the decomposition of the graph and improving the efficiency of the network plan analysis.

Abstract: The present disclosure discloses a fiber Bragg grating displacement sensor with positive and negative bidirectional measurement and free from vibration, which falls within the technical fields of fiber sensing and measurement monitoring, and aims to solve the problem that the measuring range of the existing fiber Bragg grating displacement sensor is positive, and the free end of the cantilever beam will generate vibration deformation, resulting in inaccurate displacement measurement. The sensor of the present disclosure has a positive and negative two-way displacement measurement range through the arrangement of a bidirectional measuring mechanism. In the measurement process, the cantilever beam of the vibration-avoiding mechanism is in an initial state of zero deformation, resulting in upper and lower bending deformation, so as to avoid the fatigue and failure problems caused by the cantilever beam and the fiber Bragg grating due to constant force.
