Multiobjective design of sewer networks
Authors
Abstract:
The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging in a sewer on its upstream population. To solve the problem, the NSGA-II Algorithm is coupled to two self-adaptive design algorithms for generating the layout and sizing of sewers. A case study is solved using the proposed model to demonstrate its application and advantages.

Modern communication networks often use Internet Protocol routing and the intradomain protocol OSPF (Open Shortest Path First). The routers in such a network calculate the shortest path to each destination and send the traffic on these paths, using load balancing. The issue of survivability, i.e. the question of how much traffic the network will be able to accommodate if components fail, is inc...
full textSystematic Design of Distributed Controllers for Sewer Networks
A novel concept for a systematic design procedure of a distributed controller network for global control of a sewer network is proposed. This concept is based on two simple controller types (local throttle controller, supervisory controller) which are connected systematically based on the structure of the sewer network and the available throttle and storage structures. The controllers are based...

Designing an optimal communication network is a complex, multiconstraint and multi-criterion optimisation problem. Previous work in this field has optimized a single objective or a combination of multiple values into a single scalar value. In this work, we use the multiobjective genetic optimisation technique along with the convergence to obtain a Pareto front – a set of solutions, which are no...
