Abstract

Large and complex construction projects require a timely supply of resources to reduce the construction time as well as prepare a construction plan that secures the maximum economic benefit. Because most large-scale construction sites are isolated from downtown areas, problems with the supply and demand of specific resources are frequently encountered. Previous plans with respect to resource allocation are based on uniform resource mobilization at the initial stage of construction, which is an insufficient resource supply and demand model for construction sites that have changing needs throughout the phases of construction. In this study, an active resource allocation method that the level of actual resource mobilization can be changed by the construction period is demonstrated, enabling the optimization of resource utilization to the construction site. The schedule change of resource allocation within the float time, the methods for moving a start date, the decision to increase construction time, and reasons for adjusting the width of the float time are presented in accordance with their risk level. A genetic algorithm facilitates the searching of an optimal construction schedule within the resource mobilization plan, and a case study with an example project is performed for verification.
