摘　　要：模块环境下过程模拟系统的研究已较成熟 ,并开发出许多模拟软件。过程系统综合的研究多采用基于方程的方法 ,这使得过程模拟研究成果无法得到很好地利用。为了以模块环境的化工过程模拟系统为基础 ,开发过程综合系统 ,作者提出了新的三层次化工过程系统综合的解算策略 ,在结构层中引入P矩阵并在解算过程中引入虚拟断裂物流与虚拟变量。通过实例计算表明本文所用的方法可以使计算过程更加灵活 ,提高了计算速度和效率 。Chemical process simulation system based on modular environment has been widely studied, and developed many software. Chemical process synthesis is often studied based on equation environment, then the mathematical model of the chemical unit can not be used in the process synthesis. In order to develop a process synthesis system based on a modular environment, the authors propose a new strategy. The simulator is DOPS (Data oriented process simulation system).The strategy includes three levels, superstructure level, structure level, and modular level. The matrix P is introduced in structure level and can generate matrix automatically in the modular level. The calculation algorithm is out approximation method. Example calculation shows that the strategy is more efficient, the calculation is more flexible and rapid, and the capability of convergence is improved.
