Abstract

In order to solve space conflicts in prefabricated building hoisting construction, with the conflict as research object, five kinds of object space and three kinds of space for single object were presented, three space conflict types were summarized, and consequently, quantitative evaluation indexes for spatial conflict severity were proposed. Secondly, a 3D spatial occupancy model and spatio-temporal occupancy model for different objects were developed according to construction characteristics of prefabricated buildings. Then, space conflict detection algorithm was put forward, and an multi-objective optimization model was built that minimized hoisting period, rental cost of cranes, construction cost and space conflict, which was applied into an actual prefabricated building project. The results show that this model and algorithm can effectively reduce conflict of working space and rental cost of cranes, thus optimizing hoisting schedule and improving safety performance. © 2020 China Safety Science Journal.
