摘要：The mathematical technique presented in this work deals with one step design of batch water-allocation network, where batch production schedules, water-reuse subsystems, and wastewater treatment subsystems are all taken into account. The proposed model formulation is believed to be superior to the available ones in the following aspects. In the first place, a continuous based time model is introduced and superstructures incorporating State-Task Network (STN), State-Equipment Network (SEN) and Gantt chart are adopted to capture all basic information of batch production and water-allocation network. Specifically, our superstructure is able to generate a class of optimum network structures which can never be captured by all previous frameworks. Then, costs of junctions and pipelines are added to evaluate and reduce the complexity of the network configuration. Finally, a hybrid optimization strategy integrating DICOPT and GA is developed for the resulting mixed-integer nonlinear programming (MINLP) model and one example is presented to demonstrate the advantages of the proposed approach.
