- Abstract
A paper discusses the actuality of the systematization of the space efficiency analysis and synthesis of the corresponded criteria sets. The Subject Hierarchy approach is suggested as the methodical base. The approach is based on two fundamental hierarchies, the Actor Hierarchy and Activity Metric Hierarchy. The former includes the interacting decision makers from the space industry, user community and state managing bodies like the space agency. The latter includes formalized concepts like values, interests, goals, tasks and criteria that are all together defined as ‘activity metrics’. The coordinate space is suggested built on the Actors Hierarchy and Activity Metrics Hierarchy. The transfers between the specific points of this coordinate space are associated with the typical tasks like goal definition or selection of the task set to achieve the top level goal. The orthogonal and nonorthogonal transfers reflect the different kinds of interactions between the space activities’ participants. Examples are provided of the subject hierarchy modeling of the actual space activity management and decision making problems. Being rather abstract one, the suggested approach still appears to be fruitful as the methodical basis for the current space branch system analysis, especially in Russia. The specific of the national ‘landscape’ is determined by the continuing stratification of the national space industry, space activities’ administration and space assets’ user base that had been once created in completely different situation of the total state planning and end-to-end control. Implementation of the contemporary instruments like public/private partnerships or result-oriented budgeting in the Russian space activity field call for adequate recognition and modeling of the current processes in (and between) the industry, the user community and government space activity regulation bodies.
