THE REACHABILITY,OBSERVABILITY AND PERIOD MERGING ASSIGNMENT WITH DDP OF DEDS
离散事件动态系统的能达能观性与对干扰解耦的周期合并配置

For discrete-event dynamic systems (DEDS) described by max algebra,the methods andideals of geometric theory of linear multivariable control systems put forward by Wonham areemployed in this paper to discuss the construction of the submodule which is respectivelyreachable and upper-level observable.It is concluded that a submodule which satisfies respectivereachability is just the maximal submodule whose period can be merging assigned.Some otherimportant conclusions corresponding to DDPS,OSP,RRP are also obtained.
