Application of dependence graphs and game trees for decision decomposition for machine systems

The paper concerns application of dependence graphs and parametric game trees for analysis and synthesis of dynamic properties of machine systems. Different graph solutions mean connections of input and output quantities as well as constructional parameters. The method of dependence graph distribution into the game tree structure was described. Multiple vertex numeration was introduced in order to determine subordination of elements in the system, and the additional time vertex allowed to obtain the structure with the closed loop of the feedback. The obtained graph solutions were evaluated taking into account decision decomposition into single constructional and/or service parameters.
