Discrete Firefly Algorithm for Scaffolding Construction Scheduling

摘要

Scaffolding activities involve a considerable amount of resource input and effort, particularly in very large scale and complex projects. Based on one of the present research gaps identified from literature review that very limited research emphasis has been placed on the impact of design of time-cost optimization in modular scaffolding construction process, this study aims to formulate a feasible multiobject discrete firefly algorithm (MDFA) for optimizing scaffolding project resource and scheduling schemes. The proposed MDFA has been tested under a scaffolding-specific case and a generic construction project case and manifested that it can produce accurate and effective solutions to assist scaffolding planners in developing practical project schedules and addressing complex time-cost trade-off challenges.
