Linear Optimization Model for Scheduling Repetitive Construction Projects with Multiple Crews
This study presents the development of a linear optimization model for scheduling repetitive construction projects with varying quantities of work at repetitive units to minimize project total cost. The model is capable of identifying the optimal order of executing repetitive units and considering multiple construction crews with different productivity rates. This model is developed in three main steps: (1) identifying input data; (2) formulating optimization model by identifying decision variables, formulating objective functions and constraints, and executing model computations; and (3) generating project schedule by quantifying work interruptions and cost; and identifying order of executing repetitive units for each crew. The model is designed to calculate project total cost based on direct and indirect costs. One example from the literature is analyzed to demonstrate the model capabilities and illustrate its use. The model results showed shorter project duration and cost compared to existing solutions in the literature. The model performance is verified by solving two demonstration examples from the literatures. The present model is expected to support project planners by enabling them to minimize project total cost.
