基于扩展HTN规划的作战任务分析方法

任务分析是一个认识和了解任务本质的过程,作为作战计划拟制过程中的一个核心环节,作战任务分析的结论是否准确决定着作战计划的好与坏,并影响战争的结局。为了解决目前任务分析没有统一的标准及合适方法的问题,分析了层级任务网络(HTN)在任务分析中的不足之处,给出了OOR框架进行任务细化的方法和步骤,将其作为领域知识引入HTN规划,为任务分析提供了一个有效的方法,并设计了图元素用于表示任务树中任务之间的层级关系以及时序逻辑关系。最后以空间信息支援作战为例,验证了方法的可行性和有效性。

India’s emerging space assets and nuclear-weapons capabilities

ABSTRACT

Over the last five decades, India’s nuclear and space programs have gone through several phases, from collaboration to divorce to supportive. An interplay of two factors determined the nature of the relationship. One was the state of India’s nuclear-weapon program. The second was international conditions, especially India’s relationship with the nuclear-nonproliferation regime. In the early decades, because of the rudimentary nature of India’s nuclear and space programs, the relationship was collaborative, since the rocket technology being developed was a necessary adjunct to the nuclear-weapon program. Subsequently, as India’s rocketry capabilities and nuclear-weapon program began to mature and concerns about international sanctions under the non-proliferation regime began to grow, the two programs were separated. The Indian rocketry program was also divided, with the civilian-space and ballistic-missile programs clearly demarcated. After India declared itself a nuclear-weapon state in 1998 and the programs matured, the relationship has become more supportive. As the two programs mature further, this relationship is likely to deepen, as the nuclear-weapon program requires space assets to build a robust and survivable nuclear deterrent force.
