Abstract
- The article introduces a novel method using mixed integer linear programming for optimizing sewer layouts. The research obtained the concept from obstacle-avoiding rectilinear Steiner minimal tree technique in integrated circuit routing design into our model. The Steiner nodes serve as optional nodes to link each sewer discharge node and flow to sinks on an optimal sewer layout. Those nodes are utilized for minimizing the total cost required for constructing pipes. All the nonlinear constraints and the objective function are transformed into a simple linear format. The optimization model analyzed three types of objective function conditions, solely considering the pipe cost, solely considering the ground cutting cost, and combining both considerations to illustrate the importance of considering all conditions to obtain an optimal sewer layout design. The proposed optimization model can conserve more than 38.83% of the cost required to realize the expert’s manual sewer layout design.
