Multi-criteria decision analysis for tower crane layout planning in high-rise modular integrated construction

Automation in Construction, 2021
Tower crane layout planning (TCLP) is critical to high-rise modular integrated construction (MiC) that involves multiple heavy-duty lifts. However, previous studies have rarely addressed TCLP in modular construction.
