【摘要】 修正了modi等人提出的多产品间歇化工过程最优设计的混合整数非线性规划(MINLP)模型,使之不仅允许中间贮罐的存在,还可调整以同步或异步方式操作的平行单元数.还提出了对以上模型求解的启发算法,其特点是对决策变量的初值要求低,计算速度快,所需内存小,与严格的数学规划法相比较,其相对误差小于1%.以实例说明了方法的有效性.更多还原

【Abstract】 The mixed integer nonlinear programming(MINLP) model by Modi et al. was modified for optimized design of multiproduct batch chemical processes to accomodate not only the existence of intermediate storages but also the adjustment of the number for parallel units operating in-or out-of-phase. A heuristic algorithm for solving the model mentioned above was proposed the advantages of which were lower demand for initial values of decision variables; lower storage and less CPU time for computations and relative deviation of less than 1 % in comparison with the results of using mathematical programming software (MINOS 5.0). An example was shown to prove its availabilities.更多还原
