Creating optimised employee travel plans (2018)
Presentation / Conference Contribution
Urquhart, N., & Hart, E. (2015, September). Creating optimised employee travel plans. Presented at EuroGen 2015

The routing of employees who provide services such as home health or social care is a complex problem. When sending an employee between two addresses , there may exist more than one travel option, e.g. public transport or car. In this paper we examin...

Towards reducing complexity of multi-agent simulations by applying model-driven techniques (2018)
Presentation / Conference Contribution
Hoffman, B., Chalmers, K., Urquhart, N., Farrenkopf, T., & Guckert, M. (2018, June). Towards reducing complexity of multi-agent simulations by applying model-driven techniques. Presented at International Conference on Practical Applications of Agents and Multi-Agent Systems PAAMS 2018, Toledo, Spain

Creating multi-agent simulations is a challenging task often requiring programming skills at the professional software developer level. Model driven methods of software development are an appropriate tool for reducing the complexity of the developmen...

A Domain-Specific Language For Routing Problems (2018)
Presentation / Conference Contribution
Hoffmann, B., Hoffman, B., Guckert, M., Farrenkopf, T., Chalmers, K., & Urquhart, N. (2018, May). A Domain-Specific Language For Routing Problems. Presented at 32nd Conference on Modelling and Simulation

Vehicle Routing Problems (VRPs) are commonly used as benchmark optimisation problems and they also have many applications in industry. Using agent-based approaches to solve VRPs allows the analysis of dynamic VRP instances that incorporate congestion... Read More about A Domain-Specific Language For Routing Problems.

EvoFilter is an evolutionary algorithm based tool for searching through large non-dominated fronts in order to find a subset of solutions that are of interest to the user. EvoFilter is designed to take the output of existing Multi Objective Evolutio... Read More about Evaluating the Performance of an Evolutionary Tool for Exploring Solution Fronts.

What can we learn from simulating commuters? (2017)
Presentation / Conference Contribution
Urquhart, N. (2017, November). What can we learn from simulating commuters?. Presented at U!REKA

Commuting affects just about every member of the workforce in the UK, those who do not commute are affected by the congestion and pollution generated by such activities. There is increasing pressure on organisations to adopt practices and measures th... Read More about What can we learn from simulating commuters?.

Combining parallel coordinates with multi-objective evolutionary algorithms in a real-world optimisation problem (2017)
Presentation / Conference Contribution
Urquhart, N. (2017, June). Combining parallel coordinates with multi-objective evolutionary algorithms in a real-world optimisation problem. Presented at Proceedings of the Genetic and Evolutionary Computation Conference Companion on - GECCO '17

Optimisation problems based upon real-world instances often contain many objectives. Many existing Multi-Objective Evolutionary Algorithm techniques return a set of solutions from which the user must make a final selection; typically such a set of so...

A Unifying Software Framework for Vehicle Routing and Logistics (2017)
Presentation / Conference Contribution
Enenkel, J., Geyer, J., Keiner, J., Nguyen, J., Steuler, J. L., & Urquhart, N. (2017, July). A Unifying Software Framework for Vehicle Routing and Logistics. Paper presented at Annual Workshop of the EURO Working Group on Vehicle Routing and Logistics optimization (VeRoLog), Amsterdam

A wide range of open source tools and real world data are available to support those working on vehicle routing and logistics optimisation. Despite such tools being available there is still a requirement for a unifying software API to allow researche... Read More about A Unifying Software Framework for Vehicle Routing and Logistics.

Evolving solution choice and decision support for a real-world optimisation problem (2017)
Presentation / Conference Contribution
Urquhart, N., & Fonzone, A. (2017, July). Evolving solution choice and decision support for a real-world optimisation problem. Presented at Proceedings of the Genetic and Evolutionary Computation Conference on - GECCO '17, Berlin, Germany

Agencies who provide social care services typically have to optimise staff allocations and the travel whilst attempting to satisfy conflicting objectives. In such cases it is desirable to have a range of solutions to choose from, allowing the agenc... Read More about Evolving solution choice and decision support for a real-world optimisation problem.

Information Diffusion in Multi-Agent Communities (2017)
Presentation / Conference Contribution
Farrenkopf, T., Guckert, M., Urquhart, N., & Wells, S. (2017, June). Information Diffusion in Multi-Agent Communities. Paper presented at 6th World Congress of the International Microsimulation Association, Moncalieri, Italy

Understanding the course of events when newly launched products penetrate a market, and how those products supersede existing dominant products, is crucial. Besides potential applications for business purposes the ability to simulate scenarios to mod... Read More about Information Diffusion in Multi-Agent Communities.
