> Problem statement: This study proposed a systematic model of delivering Ready Mixed Concrete (RMC) that optimizes the schedule of dispatching RMC trucks. Approach: Firstly, the factors that impact the RMC delivery process are analyzed. Secondly, a model based on Bee Colony Optimization (BCO) was developed in order to find the best dispatching schedule which minimized the total waiting duration of RMC trucks at construction sites subject to the needs of RMC deliveries from different construction sites. Results: To demonstrate its efficiency, the BCO algorithm was applied to solve two dispatching RMC problems. The simulation results obtained from the BCO are compared to those achieved from the conventional approaches i.e., Genetic Algorithm (GA) and Tabu Search (TS) algorithm. Conclusion/Recommendations: The experimental results showed that the BCO approach is can quickly generate efficient and flexible solutions to dispatching RMC trucks. Furthermore, the obtained results had higher quality solution efficiently and faster computational time than the conventional approaches.
