pThe construction of many buildings requires ready mixed concrete (RMC) delivery from concrete plants. It is common to supply multiple construction sites, simultaneously, from one or more concrete plants. In such cases, a crucial task is planning the appropriate delivery schedule to each construction site in order to minimize or avoid machinery idling. This paper presents the application of an original model developed in AnyLogic simulation software. The model is based on a hybrid approach, combining two simulation techniques: discrete event and agent-based simulation. This model addresses the supply chain problem, or transportation problem, and can solve the duration and cost of concrete delivery from up to three concrete plants to a maximum of three construction sites simultaneously. The model allows for cost optimization and several other analyses. The fleet of mixers included in the model can be adjusted before running the simulation through the OptionPlant excel file. This paper analyzes a case study based on real parameters obtained from a specific concrete plant and construction sites. Two construction sites and one concrete plant are considered. The costs of transportation, total costs, as well as pump and mixer penalty costs, are calculated. Different analyses and discussion based on conducted results are provided to improve the concrete delivery process./p
