With the increasing application of unmanned surface vehicle-unmanned aerial vehicles (USV-UAVs) in maritime supervision, research on their deployment and control is becoming vitally important. We investigate the application of USV-UAVs for synergistic cruising and evaluate the effectiveness of the proposed collaborative model. First, we build a collaborative model consisting of the cruise vehicles and communication, detection, and command-and-control networks for the USV-UAV. Second, based on an analysis of the problems faced by collaborative USV-UAV systems, we establish a model to evaluate the effectiveness of such synergistic cruises. Third, we propose a weighting method for each evaluation factor. Finally, a model consisting of one UAV and four USVs is employed to validate our synergistic cruise model.

The Impact

Cascading failures in the command and control networks (C2 networks) could substantially affect the network invulnerability to some extent. In particular, without considering the characteristics of hierarchy structure, it is quite misleading to employ the existing cascading failure models and effectively analyze the invulnerability of C2 networks. Therefore, a novel cascading failure model for command and control networks with hierarchy structure is proposed in this paper. Firstly, a method of defining the node’s initial load in C2 networks based on hierarchy-degree is proposed. By applying the method, the impact of organizational positions and the degree of the node on its initial load could be highlighted. Secondly, a nonuniform adjustable load redistribution strategy (NALR strategy) is put forward in this paper. More specifically, adjusting the redistribution coefficient could allocate the load from failure nodes to the higher and the same level neighboring nodes according to different proportions. It could be demonstrated by simulation results that the robustness of C2 networks against cascading failures could be dramatically improved by adjusting the initial load adjustment coefficient, the tolerance parameter, and the load redistribution coefficient. And finally, comparisons with other relational models are provided to verify the rationality and effectiveness of the model proposed in this paper. Subsequently, the invulnerability of C2 networks could be enhanced.

A command and control (C2) simulation system, ZZSIM is built. The characteristics of ZZSIM models are discussed, comparing System of Systems, HLA systems and complex systems. It is concluded that HLA based C2 simulation is valid. Then the communication data among C2 simulation nodes are recorded and analyzed, which shows that ZZSIM is scale-free. Therefore the data verify that ZZSIM is a valid simulation system of network centric war.

Abstract This research hypothesizes that changes in command and control along with increased levels of trust and training led to a stronger response in Colorado’s 2013 Black Forest fire than that of the 2012 Waldo Canyon fire. Because the fires were categorized as the worst in the region’s history, and because they occurred in very close succession, in roughly the same area, involving many of the same responders, the fires provide valuable insights into how the response system adapted, or failed to adapt, to overcome key events under both scenarios. The study found that the ability to tailor command and control and supporting response structures to a particular event instead of using traditional rigid frameworks were instrumental to a more effective response. The study goes on to suggest that even though the Black Forest fire was met with an improved response, a systems approach is needed to better accommodate increasingly complex future events.

Cascading failure models for command and control networks (C2 networks) continue to be a challenging and important research area. Current solutions share a common limitation because the solutions focus only on the importance of each node in isolation using one index rather than considering the contribution degree of neighboring nodes, which makes the initial load definition inaccurate and affects the cascading invulnerability of the network. To address this limitation, a new cascading failure model for C2 networks is proposed. The new model CFMAdjM, which is based on an m-order adjacency matrix, proposes a method of initial load definition using the contribution degree of m-order neighboring nodes and defines the nonlinear load capacity model according to the nonlinear relationship between load and capacity. Finally, the influence of model parameters on the cascading failure of C2 networks is analyzed through simulation, and the results demonstrate that the new model effectively resists the cascading failure and enhances the survivability of the network by defining the initial load and adjusting the coefficient appropriately.

It is no surprise that just like the previous years, this year as well China has expanded its military budget, put another ship to sea, demonstrated new weaponary at the military parade, etc. For the last two decades, all the combat arms of the Chinese army has been developing at a high rate. Many authors claim very specific reasons for the Chinese armaments especially highlighting the conflicts with its immediate neighbors. From a geopolitical point of view, an interesting balance of power is being formed in the East. It’s been several years now that there are some precise problems in China-Japan conflict related to the power over some islands. China actively builds artificial islands which can serve as military bases far away from its shores approximately at an operative depth. And this matter deeply concerns the Philippines and Vietnam. In this light, it would be very interesting to study the balance of forces in the region and to analyze the American military doctrine on the one hand and the Chinese specific military and military-political attempts to appose it on the other hand. It is common knowledge that in political and professional circles in the USA are concerned about the actions and capabilities of China and Russia, which can considerably restrict the US access to key regions of Eurasia: Today, China and Russia have great potential to influence on the traditional American Net-platform weaponary, Air Forces, Navy, command and control networks, and even the orbital groupings. The two countries mentioned above, which are perceived as potential adversaries in the USA, strive to reach the level of the American military by all possible means and develop powerful techonologies. Russia and especially China are designing powerful satellite systems, various long-range missiles, fighter jets, UAVs, etc. New Electronic Warfare (EW) systems are being developed, to suppress or weaken the command and management systems of the US or its allies. The People’s Liberation Army (PLA) of China also has the capacity to destroy settelites, disrupt extraterrestrial intelligence, wreck command and control networks, etc. According to experts, there is no guarantee that the armed forces of the USA can ensure reliable and secure communication and conncetion during conflicts on the theater of military operations, in particular on operational and strategic levels.
