The comprehensive performance and deployment optimization of the ready-mix concrete pumping conveyance and construction system based on queuing method were focused on.The main parameters of the concrete pumping conveyance system were set on the basis of construction engineering practices.An M/M/m queuing model for the concrete pumping conveyance system was established and its performance indicators were analyzed.By applying simulation tools to establish a queuing simulation model for the concrete pumping conveyance system,influences of the number of concrete pumps on the system performance were discussed.It is revealed that while adding more concrete pumps,the system performance is improved,the pumping working time declines,the truck queuing length and time decrease,and more concrete trucks are serviceable.It is obersrved that an optimal number of pumps exsits for the system.An optimal model for deploying the concrete pumping conveyance system was presented,and the relationships among the number of concrete pumps,the efficiency of concrete pumps,and the arrival frequency of concrete trucks were investigated.Several means were suggested to improve the performance of concrete pumping construction system.
