Many (metaheuristic) techniques for water distribution network (WDN) design optimisation already have been developed. Despite of the aforementioned scientific attention, only few, high-quality benchmark networks are available for algorithm testing, which, in turn, hinders profound algorithm...

Using a structured design methodology, we develop an eXcient iterated local search metaheuristic for the water distribution network design optimisation problem. The algorithm outperforms existing algorithms in the literature while being considerably less complex. Our approach is — contrary to...

This paper surveys the literature on the optimisation of water distribution network design. The water distribution network design (WDND) optimisation problem entails nding the type and diameter of each pipe in the network so that the total cost of the network is minimised without violating any...

This paper surveys the literature on the optimisation of water distribution network design. The water distribution network design (WDND) optimisation problem entails finding the material and diameter of each pipe in the network so that the total cost of the network is minimised without violating...

Real-life utility networks such as smart grids, pipelines and water networks can be exposed to safety and security related risk. Preventative measures can be applied to mitigate such risks that may result in service interruptions for the users of these networks. An index of (dis)connectivity,...

The Vehicle Routing Problem with Backhauls (VRPB) is an extension of the VRP that deals with two types of customers: the consumers (linehaul) that request goods from the depot and the suppliers (backhaul) that send goods to the depot. In this paper, we propose a simple yet effective iterated...

Horizontal collaboration among shippers is gaining traction as a way to increase logistic efficiency. The total distribution cost of a logistic coalition is generally between 9% and 30% lower than the sum of costs of each partner distributing separately. However, the coalition gain is highly...

In this paper, the multiple travelling salesperson problem with hotel selection (m-TSPHS) is presented. This combinatorial optimisation problem is a generalisation of both the travelling salesperson problem with hotel selection (TSPHS) and the multiple travelling salesperson problem (m-TSP). As...

Stated choice experiments are conducted to identify the attributes that drive people's preferences when choosing between competing options of products or services. They are widely used in transportation in order to support the decision making of companies and governmental authorities. A large...
