By considering both definition of ‘marine resource management’ by IMO and the current research status of crew assessment in China, the evaluation index systems are established for the two kinds of seafarer.

We study about robust H∞ control problem of generalized delta operator system which have uncertainty of derivative. However, to study the robust H∞ control problem, we first give about sufficient and necessary conditions for the admissibility of generalized delta operator system which has uncertainty of derivative. The sufficient and necessary conditions for the robust H∞ control problem of linear...
