A dynamic truck dispatching problem in marine container terminal (2016)
Presentation / Conference Contribution
Chen, J., Bai, R., Dong, H., Qu, R., & Kendall, G. A dynamic truck dispatching problem in marine container terminal. Presented at 2016 IEEE Symposium on Computational Intelligence in Scheduling and Network Design (IEEE SSCI 2016)

In this paper, a dynamic truck dispatching problem of a marine container terminal is described and discussed. In this problem, a few containers, encoded as work instructions, need to be transferred between yard blocks and vessels by a fleet of trucks...

An application programming interface with increased performance for optimisation problems data (2016)
Journal Article
Pinheiro, R. L., Landa-Silva, D., Qu, R., Constantino, A. A., & Yanaga, E. (in press). An application programming interface with increased performance for optimisation problems data. Journal of Management Analytics, 3(4), https://doi.org/10.1080/23270012.2016.1233514

An optimisation problem can have many forms and variants. It may consider different objectives, constraints, and variables. For that reason, providing a general application programming interface (API) to handle the problem data efficiently in all sce...

Hybridising local search with Branch-and-Bound for constrained portfolio selection problems (2016)
Presentation / Conference Contribution
He, F., & Qu, R. Hybridising local search with Branch-and-Bound for constrained portfolio selection problems. Presented at 30th EUROPEAN Conference on Modelling and Simulation

In this paper, we investigate a constrained portfolio selection problem with cardinality constraint, minimum size and position constraints, and non-convex transaction cost. A hybrid method named Local Search Branch-and-Bound (LS-B&B) which integrates... Read More about Hybridising local search with Branch-and-Bound for constrained portfolio selection problems.
