In batch process, message structure of process consists of discrete state and continuous state. This paper researches on problems such as description, control and optimization in batch process which has hybrid message structure by means of the automaton model. 在间歇生产过程中,过程的信息结构由离散状态和连续状态构成.本文以自动机为工具,研究具有混合信息结构的间歇生产过程的描述、控制与优化等问题。
