A collaborative simulation monitor system of ship based on patterns

Computer simulation has been widely used in scientific research. But the present simulation systems are mostly designed for a specific purpose, which can only be applied in specific research experiment, so the expansibility is not good. The main purpose of pattern technology is to extend the technologies of software reuse based on Object Oriented ^[1]. Pattern technology can reuse not only the codes of function modules, but also the structural design of system software. In the design and implementation of the collaborative ship simulation monitor system mentioned in this paper, kinds of pattern technologies have been used. The system has not just the characteristics of high efficiency, easy to extend and maintain, but also the characteristic of high reusability.
