چکیده
For to identify functioning problem of railway lines various mechanisms are used, including the mechanism low-intensity line exploitation diagnostics which allows raise their efficiency. The proposed evaluate current state and establish cause-and-effect relationships leading unprofitability, give analysis indicators greatest extent influence negatively functioning. Cognitive modeling method is used for this purpose. article develops enlarged cognitive map that’s existing state. consists concepts, links between concepts links’ weight values. On basis, adjacency matrix made up reliability sustainability fuzzy according internal external disturbances. Characteristic equation eigenvalues calculated allow assessment in form on system concepts. Fuzzy established, namely, consonance, dissonance, concept most complete representation structure. “Technical resources”, “stations’ section’s staff”, “normative base” among touch largest positive impact system. significant listed will rise operation efficiency lines. “Traffic volume” causes negative because lack quantity train pairs, passing along line, a day. plan experiments define changes parameters “Productivity effectiveness” when exerting impulse influences “Operational management”, resources” “Stations’ staff” with purpose evaluation “Productivity” “Efficiency” up. When introducing impulses into “Staff” concept, productivity growth observed that testifies possibility by way concept.
