Decomposition of efficiency in a network

Today, the network has an important role in a system. Determining the efficiency of the system as well as the efficiency of the sub-sections of a network helps to effectively manage the network. If the optimal value of the sub-sections is not unique, an efficiency range can be obtained for them. In this paper, the performance of a network is analysis with the help of data envelopment analysis and performance intervals are determined for each of the sub- sections of the network. With help decomposition the performance of a network structure, the performance of its components was obtained. The relationship between component performance and interval value was calculated with the overall efficiency network.
