Service path choice of satellite application information chain based on Metagraph
Dishan Qiu · Computer Engineering and Applications Journal · 2012
The service process of satellite information includes the entire loop.The loop begins when the task request is issued from combat unit and ends until the service response.Metagraph can describe the rule of information status transformation in the whole process from satellite download information requisition to the final satellite application products and service generation.A new modeling method of Satellite Application Information Chain(SAIC)based on Metagraph is proposed.The SAIC service path is calculated using the maximum Metapath iterative algorithm based on incidence matrix.The solution idea of the problem of satellite application analysis,modeling,design and evaluation is expanded.The decision support is provided for the whole service process of satellite application.
