In modern process industries , with the rapid development of mass production and complexity , reliability and security are being greatly needed to avoid large economical loss brought by accidents and even breakdowns of industrial productions 随着现代工业过程系统大型化和复杂化的迅速发展,人们迫切需要提高系统的可靠性和安全性,以避免事故发生甚至系统崩溃造成的巨大经济损失。
Automatic differentiation ( ad ) , which is well recognized as the most promising differentiation algorithm in pso and has been developed rapidly in recent twenty years , is a technique for augmenting computer programs with derivative computations 在过程系统优化中,一个理想的求导算法应该能够快速求取程序模块的解析导数。近年来发展迅速的自动微分算法比较好地满足了这个条件,并已在优化中得到了广泛的应用。
2 ) contraposed the poor openability and adaptability of field process control system , the data interface software and the client explorer for more server software have been developed . those software have been successfully applied in many projects 2 )针对现场过程系统中开放性差、适应性弱等问题,设计开发了基于opc技术的两个应用软件组件,即数据接口软件jxextend和通用多服务器客户端浏览器软件clienzview 。
Module - oriented automatic differentiation ( mad ) , a new ad approach that can employ current differentiation algorithms flexibly to differentiate each module of the process model , is presented to achieve more efficient jacobian evaluation in optimization 面向模块的自动微分可以更加灵活和充分地利用模型的结构特点,这个优势在精馏塔稳态优化和缩聚反应釜动态优化这两个典型的工业过程系统优化问题中得到了充分的体现。
Abstract : it is proved that system heat quantity absorbing by reversible and irreversible process is not equal , so , the paper points out that merge formulas on mathematical expansion of the second law of thermodynamics are incorrect , and raises the proposition of correct expansion 文摘:通过证明可逆和不可逆两种过程系统吸收热量的不相等,指出将热力学第二定律表示式写成合并式的作法是不妥的,并提出了正确表示的建议。
