Abstract: It is a difficult issue to design metrics of measure of the OSOS capabilities, which are emergent properties of OSOS. The concept of the OODA loop robustness was proposed and it was closely related to the overall capabilities of OSOS. A new method to measure the OODA loop robustness was discussed. The OSOS combat network mode was established l. Based on the weighted network, the Perron-Frobenius Eigenvalue (PFE) of the adjacency matrix of the network was used to measure the OODA loop robustness. Simulations show that there is a strong correlation between the PFE and the metric of OSOS operational effectiveness, which verifies that the PFE metric is useful in the OSOS capabilities evaluation.

Key words: OODA loop, robustness, SoS network model, capabilities evaluation, Perron-Frobenius eigenvalue
