Hospital Renovation Construction Project Scheduling with Special Relationships

A hospital renovation construction project has a total of twenty-four main activities. The project has a resource limitation and specified contract time. The efficient schedule of this project is arranged using the new resource-constrained scheduling problem (RCSP) which is aimed to determine the optimum project resource utilization. This new RCSP shifts the start time of the activities and determines the alternatives of precedence relationships of some activities to obtain optimal solutions. The model is developed using Microsoft Excel and the Genetic Algorithm optimization. Five schedule performance indices (i.e. project duration, maximum daily resource demand, release and re-hire resources, resource idle days, and resource fluctuation moment) are used to evaluate the solutions. The results show that the model which uses a suitable weighting proportion can improve solutions with the efficient resource utilization profiles, lower resources required, and shortened project duration. Hence, this model can help planners choose both suitable activities' start times and relationship options.
