Facing the continuous improvement of war complexity under the trend of system-of-systems confrontation, this paper introduces MBSE to the modeling design of complex system-of-systems combat. Adopting Unified Architecture Framework, a modeling method based on scenes is proposed by sorting out the modeling needs and internal mechanisms of system operations. Taking the task that searching and attacking multiple target as an example, various kinds of view is constructed including strategic, operating, resources and services. Then, logic verification is carried out based on the model. This method can provide a reference for system-of-system combat design and UAF application. [ABSTRACT FROM AUTHOR]

The aviation system has experienced an increasing demand over the last decade since it is considered one of the optimal means of transportation. As a result of this increasing demand, aviation organizations have been forced to focus on passenger safety by keeping aircraft airworthy at all times and by investing in the maintenance sector. Recent literature shows that the maintenance sector is still using outdated technology to maintain documentation of an aircraft's maintenance system. This article proposes the use of model-based system engineering (MBSE) as an approach to document aircraft maintenance systems. Systems modeling language (SysML) provides the maintenance system with a more systematic application that would automatically update maintenance records and provide stakeholders with more precise documentation. SysML is expressed through the use of structural and behavioral diagrams for the EA-6B aircraft. This article also provides a look into the use of SysML in the modeling of complex system architecture and the interaction between various systems. The integration of reliability studies and SysML is showcased through a case study. A failure mode and effect analysis is performed to show the usability of SysML in conducting reliability analysis. This article serves as a foundation for practitioners who aim to use MBSE methodology to solve the current setbacks existing in the maintenance aviation sector. [ABSTRACT FROM AUTHOR]

In present study, a history analysis and review of last 30 years for U.S. naval ship concept design development trend is proposed. Based on the development of naval ship concept design model history, the three features of development process are further summarized. The first is that model-based system engineering (MBSE) becomes the basic of naval ship concept design, while the second one is that the multi-discipline crossing and combination becomes a general innovation model. And the third one is that systematization oriented naval system integration is the developing goal. Some detailed examples are presented to illustrate these three characteristics. Finally, the technology difficulties in naval ship concept design are also presented. [ABSTRACT FROM AUTHOR]
