Right now the priority for the future is to radically change the core of OE, to eliminate the instability of the programming (that is especially evident in 3.10) and to gain some more space for the ram. But this probably will take several versions before it is finishing, due to the complexness of the process.

似乎这次v3.30 OE自制系统将会没有携带新功能出现的主要问题是出现在硬件设计上，如果加入新功能可能将从根本上改变OE核心，这样可以增加系统的稳定性，这些都需要更多FLASH空间的。

The basic concept and characteristics of missile system-of systems combat simulation for effectiveness evaluation were summarized and the problems of simulation model specification were analyzed, then the hierarchical description and composition method based on system-of-systems, entity and behavior was proposed as the modeling methodology of system-of-systems combat simulation, which is SEB composable modeling methodology. Then, the reference model of SEB methodology and the modeling reference view of various hierarchies were discussed.

总结了面向效能评估的导弹体系对对仿真基本概念和特点，分析了体系对抗仿真模型描述中存在的主要问题，在此基础上，提出体系－实体－行为的分层组合描述方法，作为体系对抗仿真的建模方法，即SEB组合建模方法，并给出其参考模型和各个层次建模的参考视圈。
