Abstract:

To deal with reliability of optimal design and operation of water-using systems, an operating window method and its procedure were proposed for sub-optimal designs and operations of water-using systems, in which inlet and outlet concentrations were considered noise factors, while sub-optimal targets of the water-using system were taken as control factors.The searching strategy of operating parameters for sub-optimal operations was also proposed.The operating parameters were obtained through mathematical programming.A case study was used to show the feasibility of the proposed method.It will provide theoretical fundamentals to analyze the sub-optimal design and operational reliability of water-using systems.
