This paper proposes and evaluates an efficient approach for loading models stored in a change-based format. The work builds on language-independent change-based persistence (CBP) of models conforming to object-oriented metamodelling architectures suc...

Competition and cooperation in pickup and multiple delivery problems (2017)
Presentation / Conference Contribution
Mourdjis, P., Polack, F., Cowling, P., Chen, Y., & Robinson, M. (2017). Competition and cooperation in pickup and multiple delivery problems. Communications in Computer and Information Science, 695, 142-160. https://doi.org/10.1007/978-3-319-53982-9_9

Logistics is a highly competitive industry; large hauliers use their size to benefit from economies of scale while small logistics companies are often well placed to service local clients. To obtain economies of scale, small hauliers may seek to coop... Read More about Competition and cooperation in pickup and multiple delivery problems.

Evaluating hyperheuristics and local search operators for periodic routing problems (2016)
Presentation / Conference Contribution
Chen, Y., Mourdjis, P., Polack, F., Cowling, P., & Remde, S. (2016). Evaluating hyperheuristics and local search operators for periodic routing problems. Lecture notes in computer science, 9595, 104-120. https://doi.org/10.1007/978-3-319-30698-8_8

Meta-heuristics and hybrid heuristic approaches have been successfully applied to Periodic Vehicle Routing Problems (PVRPs). However, to be competitive, these methods require careful design of specific search strategies for each problem. By contrast,...

A tutorial on metamodelling for grammar researchers (2014)
Presentation / Conference Contribution
Paige, R. F., Kolovos, D. S., & Polack, F. A. (2014). A tutorial on metamodelling for grammar researchers. Science of Computer Programming, 96(P4), 396-416. https://doi.org/10.1016/j.scico.2014.05.007

A metamodel has been defined as: a model of a model; a definition of a language; a description of abstract syntax; and a description of a domain. Because of these varied definitions, it is difficult to explain why metamodels are constructed, what can... Read More about A tutorial on metamodelling for grammar researchers.
