Abstract Considering spatiotemporal feature of spatial scheduling in block construction and irregular projection shape of blocks, an optimization model which takes time and space as the optimization objectives was proposed. In order to approach actual situation, blocks are thought as irregular polygons. Interference checking and suspension test are used to avoid the phenomenon of suspension and overlap in spatial scheduling. An improved particle swarm optimization method was designed and average adaptive approach was used to determine weights for different optimal goal in the spatial scheduling algorithm. The simulation results validate the effectiveness of the proposed approach, showing that this algorithm can improve the spatial utilization and reduce the complete processing time effectively.
