The common attribute of the geo-distributed systems (GS) is the way of their organization. The structure of GS is usually an up-down depended hierarchy where the processes of their inter work control are implemented as two sides (up-down, down-up) information exchange. As a result, the subcomponents of typical GS are in some distance from each other. The main clue of GS manager is the quality of information process flow and a medium of data exchange. The state of art of data describes technologies, e.g. XML (eXtensible Markup Language) [1, 2, 3] and the progress of the Internet interoperabilitation, especially in Web Services [4], gives for the designers some new opportunities of application design. In this way, the layer of data interchange of GS subcomponents will migrate to the next/new level of abstraction. Its consequence is ability of reorganization of the controlled object structures and modelling of dimensions extends. This article presents a model of hierarchical system of distributed objects work control (HCS). The model is based on a cube of data repository and dedicated web serviced methods. This model is used in the investigations of the electric energy consumption control by the author.
