Abstract:

Mapping from operational domain to technology domain is full of difficulties, but it is also the emphasis of developing requirements of an equipment system. Therefore, an approach to matching capabilities towards tasks，which is the key to the mapping, is put forward. The structure of the measures of requirements of an equipment system is studied. Requirements are expressed as task needs，capability needs and capability gap. Capability needs and task needs are related with system function and operational activity. Accordingly the process is divided into four phases to get them. Included are operational task analysis, function and activity analysis, operational capability analysis and capability gap analysis. In order to help communicate requirements clearly，the necessary models in every phase are provided. Finally，an example about an air interdiction operation is presented for specifying the relations among the phases and the objects of every phase. The example shows that the approach is feasible，effective and promising.
