摘　　要：离散事件动态系统(DEDS)矩阵模型是一种逻辑运算与代数运算的混合系统。该矩阵模型给出了分析和仿真DEDS的严格框架，并用类似于控制理论状态方程的分析方法描述系统的动态行为。该文采用一种Petri网描述的适用于仿真的DEDS矩阵模型，用Matlab语言，对某炼钢厂炼钢连铸生产过程进行了实例研究。该方法比一般Petri网分析法简洁、完备，并有严密的数学描述和分析手段。Matrix model for discrete event dynamic simulation (DEDS) is a hybrid system with logical and algebraic components. This new matrix formulation is suitable to analyze and simulate the DEDS, and can describe the dynamic behavior of DEDS, which is analogous to the state equation in control system theory. Based on the matrix model and Petri net, the authors apply this approach to the simulation of a steelmaking process using Matlab 5.3. Compared with the conventional Petri-net analysis, it is simpler and more perfect, and provides rigorous measure of mathematical description and analysis.
