Abstract: The state of the art process modeling and optimization software was reviewed. Motivated by increasing demand on modeling and optimization of systems with large-scale and high complexity characteristics, a new application mode with service-oriented open architecture was proposed.ASCEND (advanced system for computations in engineering design) was chosen as the base for equation-oriented modeling. Its inherent structure, data flow, working mode and communication interface were redefined and reconstructed. With support from COM/DCOM/AUTOMATION technology, AscendServer was built as the core service providing modeling and optimization functionalities. Some key issues such as componentization, event handling and coordination between processes were discussed in details. Within this superstructure, modeling and optimization for large-scale complex systems could be integrated with more extensive data exchange, more flexible application mode and more adaptative capabilities. A data reconciliation system of water consumption balancing for a petrochemical company was given to verify the efficiency and functionalities of the new open structure service for modeling and optimization.

摘要： 分析了复杂过程系统建模优化软件的需求与现状，提出了一种面向服务的开放架构的应用模式.以复杂系统开放方程建模软件ASCEND为基础，对其内在结构、运行模式、外部接口等进行了重组，在AUTOMATION技术支持下实现了AscendServer建模优化核心服务器(组件)，能提供基于组件化封装、消息驱动机制和进程间协同工作的一种应用程序接口，使得大规模、复杂系统的建模与优化能够具有更广泛的数据交互、更弹性的应用模式、更强的适应性.某石化企业PTA生产过程水平衡数据调和计算实例验证了这种开放架构优化求解服务的有效性.
