[Abstract]:The scheduling of electronic measurement information resources in the network can effectively improve the utilization rate of network information resources. For the scheduling of electronic measurement information resources, we need to obtain the distribution difference of information scheduling attribute values, calculate their relative weights, and complete the effective scheduling of measurement information resources. The traditional method obtains the trust attribute of each information and gives the trust benefit function of each measurement information, but neglects to calculate its relative weight, resulting in the information resource scheduling effect is not ideal. An effective scheduling method for electronic measurement information in networks based on multi-attribute information is proposed. Based on the calculation of the dependent relation among the large-scale measurement information scheduling attributes, the distribution difference of the measurement information scheduling attributes is obtained, and the relative weights of the measurement information scheduling attributes are calculated. Combining DPA scheduling priority preemption method to calculate the immediate value of the information task, the ratio of the current residual value density to the initial residual value density is obtained, and the ratio of the execution time needed to complete the information task to the task spare time is calculated. Based on this, the effective scheduling of electronic measurement information in the network is completed. The experimental results show that the proposed method has high scheduling accuracy and can effectively improve the utilization rate of electronic measurement information resources.
