Research on Dynamic Mechanism of Hotel Industry System Evolution;

By analyzing the challenge of the evolution practice in system-of-systems, this research focuses on the evolution issues of enterprise information systems and aims to develop a system evolution environment (SEE) t o investigate new methods and tools, and to properly manage and to instruct the evolution practice by leveraging system architecture knowledge.

The article presents self-examination the writer made on the problems about objective after reading Mr Jin Guantao s philosophical analysis in his book System Philosophy on system evolution problems.

Due to the absence of the Sobolev embedding compactness,the idea of asymptotical compactness for random evolution systems introduced by Crauel,Debussche and Flandoli will be no longer suitable for random dynamical systems on unbounded domain.
