A bi-objective optimisation technique for scheduling repetitive projects

Repetitive projects are projects in which the same type of works/activities gets repeated in different locations or sites. For each of this type of projects, different crew options are available for each activity and selecting the best option corresponding to each activity is a difficult task. Project managers in these projects are often faced with the task of finding out the best schedule corresponding to the optimum project duration and expenditure which will satisfy different constraints. Since the computational complexity is very high in these types of projects, an ABC algorithm-based heuristic methodology is developed in this study, which can give good solutions for satisfying the above mentioned objectives with respect to different constraints. The proposed methodology's performance is analysed with exact solutions and the results show that an ABC algorithm-based methodology gives significantly good quality solutions.
