Computational study for workforce scheduling and routing problems (2014)
Presentation / Conference Contribution
Castillo-Salazar, J. A., Landa-Silva, D., & Qu, R. Computational study for workforce scheduling and routing problems. Presented at 3rd International Conference on Operations Research and Enterprise Systems (ICORES 2014)

We present a computational study on 112 instances of the Workforce Scheduling and Routing Problem (WSRP). This problem has applications in many service provider industries where employees visit customers to perform activities. Given their similarity,...

An evolutionary algorithm for graph planarisation by vertex deletion (2014)
Presentation / Conference Contribution
Pinheiro, R. L., Constantino, A. A., de Mendonca, C. F. X., & Landa-Silva, D. An evolutionary algorithm for graph planarisation by vertex deletion. Presented at 16th International Conference on Enterprise Information Systems (ICEIS 2014)

A non-planar graph can only be planarised if it is structurally modified. This work presents a new heuristic algorithm that uses vertices deletion to modify a non-planar graph in order to obtain a planar subgraph. The proposed algorithm aims to delet...

Particle swarm optimization for the Steiner tree in graph and delay-constrained multicast routing problems (2013)
Journal Article
Qu, R., Xu, Y., Castro-Gutierrez, J., & Landa-Silva, D. (2013). Particle swarm optimization for the Steiner tree in graph and delay-constrained multicast routing problems. Journal of Heuristics, 19(2), https://doi.org/10.1007/s10732-012-9198-2

This paper presents the first investigation on applying a particle swarm optimization (PSO) algorithm to both the Steiner tree problem and the delay constrained multicast routing problem. Steiner tree problems, being the underlining models of many ap... Read More about Particle swarm optimization for the Steiner tree in graph and delay-constrained multicast routing problems.

Overview of telematics-based prognostics and health management systems for commercial vehicles (2013)
Journal Article
Mesgarpour, M., Landa-Silva, D., & Dickinson, I. (2013). Overview of telematics-based prognostics and health management systems for commercial vehicles. Communications in Computer and Information Science, 395, https://doi.org/10.1007/978-3-642-41647-7_16

Prognostics and Health Management/Monitoring (PHM) are methods to assess the health condition and reliability of systems for the purpose of maximising operational reliability and safety. Recently, PHM systems are emerging in the automotive industry.... Read More about Overview of telematics-based prognostics and health management systems for commercial vehicles.

A Survey on Workforce Scheduling and Routing Problems (2012)
Presentation / Conference Contribution
Castillo-Salazar, J. A., Landa-Silva, D., & Qu, R. (2012, August). A Survey on Workforce Scheduling and Routing Problems. Presented at PATAT 2012 - Proceedings of the 9th International Conference on the Practice and Theory of Automated Timetabling, Oslo, Norway

© PATAT 2012. In the context of workforce scheduling, there are many scenarios in which personnel must carry out tasks at different locations hence requiring some form of transportation. Examples of these type of scenarios include nurses visiting pat... Read More about A Survey on Workforce Scheduling and Routing Problems.

An evolutionary non-Linear great deluge approach for solving course timetabling problems (2012)
Journal Article
Obit, J. H., Ouelhadj, D., Landa-Silva, D., & Alfred, R. (2012). An evolutionary non-Linear great deluge approach for solving course timetabling problems. International Journal of Computer Science Issues, 9(4),

The aim of this paper is to extend our non-linear great deluge algorithm into an evolutionary approach by incorporating a population and a mutation operator to solve the university course timetabling problems. This approach might be seen as a variati... Read More about An evolutionary non-Linear great deluge approach for solving course timetabling problems.

Evolutionary local search for solving the office space allocation problem (2012)
Presentation / Conference Contribution
Ulker, O., & Landa-Silva, D. Evolutionary local search for solving the office space allocation problem. Presented at 2012 IEEE Congress on Evolutionary Computation (CEC 2012)

Office Space Allocation (OSA) is the task of correctly allocating the spatial resources of an institution to a set of entities by minimising the wastage of space and the violation of additional constraints. In this paper, an evolutionary local search... Read More about Evolutionary local search for solving the office space allocation problem.

Designing a multi-agent approach system for distributed course timetabling (2011)
Presentation / Conference Contribution
Obit, J. H., Landa-Silva, D., Ouelhadj, D., Khan Vun, T., & Alfred, R. Designing a multi-agent approach system for distributed course timetabling. Presented at Proceedings of the 2011 IEEE Hybrid Intelligent Systems Conference (IEEE-HIS 2011)

This paper proposes tackling the difficult course timetabling problem using a multi-agent approach. The proposed design seeks to deal with the problem using a distributed solution environment in which a mediator agent coordinates various timetabling...
