Simultaneous optimization of batch process schedules and water-allocation network

摘要：

A systematic design methodology is developed in this work for optimizing batch process schedules and water-allocation network in a simultaneous manner. The proposed model formulation is believed to be superior to the available ones in the following aspects. In the first place, a continuous-time based batch process scheduling model is introduced. Then, an improved state space superstructure is adopted to capture the structural characteristics of the integrated water-allocation network for batch process, and a mixed-integer nonlinear program (MINLP) is formulated accordingly. In addition, costs of splitters and mixers are added to evaluate and reduce the complexity of the network configuration. Finally, a hybrid optimization strategy integrating DICOPT and GA is developed and, also, an interactive iteration method is adopted based on sensitivity analysis to guide the search toward a potential global optimum. One illustrative example is presented to demonstrate the validity and advantages of the proposed approach.
