针对混合生产过程的特性 ,提出了采用扩展时间事件图 ( ETEG)建模方法 ,用位置的初始标志表示系统的配置 ,并采用 Dioid代数推出 ETEG的伪线性代数方程组 ,在此基础上计算最优初始标志 ,从而求得系统的最优配置 .最后以一个例子说明本方法的有效性 .

This paper proposes an extended-timed-event-graph(ETEG)-based modeling method for hybrid processes and expresses system parameters by initial tokens of places of the ETEG. Then we use Dioid algebra to deduce its pseudo-linear algebraic equations, based on which we calculate optimal initial tokens to get optimal equipments. In the end an example is given to show the effectiveness of this method.
