Engineering Modeling Programming and Implementation of Process Optimization

Several subjects were studied based on mathematical programming theory including multivariable local model refining,and modeling and integration of multi-solvers of linear/nonlinear.General integrated extensible programming tool(GIETP) was designed based on Fedora 12/Linux Platform by using C+ +/GCC and wxWidgets(GUI toolkit).Several functions had been integrated in the GIEPT including different types of programming solvers,the unified standard using XML-based schema and the common solver interface based on syntax tree.GIETP will be able to solve different types of programming problems by using a uniform specification to input programming models,and meanwhile GIEPT can be run in multi-platform because of its platform independent nature.Finally,GIEPT was tested and evaluated by using standard test problems linear and nonlinear optimization and a binary distillation column.Results show that GIEPT can solve large scale nonlinear programming problems and has the significant effect in industrial application.
