  The paper describes some basic approaches to detection of bottlenecks in
composite (modular) systems. The following basic system bottlenecks detection
problems are examined: (1) traditional quality management approaches (Pareto
chart based method, multicriteria analysis as selection of Pareto-efficient
points, and/or multicriteria ranking), (2) selection of critical system
elements (critical components/modules, critical component interconnection), (3)
selection of interconnected system components as composite system faults (via
clique-based fusion), (4) critical elements (e.g., nodes) in networks, and (5)
predictive detection of system bottlenecks (detection of system components
based on forecasting of their parameters). Here, heuristic solving schemes are
used. Numerical examples illustrate the approaches.
