Abstract
Prefabricated buildings are the direction of the future development of the construction industry and have received widespread attention. The effective execution of prefabricated construction project scheduling should consider resource constraints and the supply arrangement of prefabricated components. However, the traditional construction resource-constrained project scheduling implementation method cannot simultaneously consider the characteristics of the linkage between component production and on-site assembly construction. It cannot also fully adapt to the scheduling implementation method of the prefabricated construction projects. It is difficult to work out a reasonable project schedule and resource allocation table. In order to determine the relevant schedule parameters that can reflect the actual construction situation of the prefabricated building and meet the scheduling requirements of the prefabricated project, this study proposes a prefabricated construction project scheduling model that considers project resource constraints and prefabricated component supply constraints. Additionally, it improves the design of traditional genetic algorithms (GAs). Research results of the experimental calculation and engineering application show that the proposed project scheduling optimization model and GA are effective and practical, which can help project managers in effectively formulating prefabricated construction project scheduling plans, reasonably allocating resources, reducing completion time, and improving project performance.
Highlights
In recent years, the construction industry has paid increasing attention to the use of modular prefabricated parts
The unreasonable project scheduling plan formulated due to the failure to fully consider the characteristics of the prefabricated building will make it difficult for on-site construction activities to be implemented as planned, resulting in a series of negative ripple consequences; prefabricated construction projects cannot be completed on time and the cost increases [10]
The remaining sections of this study are arranged as follows: the Section 2 reviews the related research; the Section 3 establishes the mathematical model of the prefabricated construction project scheduling problem; the Section 4 introduces the designed genetic algorithms (GAs) in detail; the Section 5 provides a series of calculation results by using PSPLIB test examples to verify the effectiveness of the algorithm; the Section 6 applies the proposed model and algorithm to the actual application
Summary
The construction industry has paid increasing attention to the use of modular prefabricated parts. This study has developed a prefabricated construction project scheduling optimization model that is more intuitive and easy to solve to make up for the failure to fully consider the impact of the supply of prefabricated components on the scheduling model and the limitations of simulation modeling in the previous research [16,23]. The remaining sections of this study are arranged as follows: the Section 2 reviews the related research; the Section 3 establishes the mathematical model of the prefabricated construction project scheduling problem; the Section 4 introduces the designed GA in detail; the Section 5 provides a series of calculation results by using PSPLIB test examples to verify the effectiveness of the algorithm; the Section 6 applies the proposed model and algorithm to the actual application. It is necessary to use GA to solve the project scheduling problem and explore more efficient and reasonable genetic operation design to solve the actual engineering project scheduling problem under resource constraints
