According to the reality of the railway oil supply chain, this paper proposes a BSC-SCOR model in five-dimension to overcome the shortcomings of the traditional BSC model, and establishes a more objective and comprehensive supply chain performance evaluation indicator system. This research uses AHP method, integration algorithm and fuzzy comprehensive evaluation to calculate the performance of the railway oil supply chain.

Inverted pendulum system is a non-linear，natural instability and uncertain system. As a controlled objects of control system in mechanical industry, it can be analysis and verification by different control theory and methods. The paper analysis the non-linear inverted pendulum system, then deduces sufficiency conditions of the existence of controller with state feedback. It utilizes standard digital software to get the answer. The feasibility and robustness is demonstrated by numerical examples.
