Simulating a ready-mix concrete plants network using multimethod approach

The operation of ready-mix concrete (RMC) plants is strongly affected by the complex stochastic nature of the concrete production and delivery processes. The delivery compliance in the different building sites is one of the most significant aspects for both customer satisfaction and resource allocation in the RMC industry. To improve the decision-making process in the RMC industry, a multi-method (using a hybrid Agent-based and Discrete-Event simulation modeling technique) simulation model was created for a multinational company that produces and markets cement and ready-mixed concrete using software Arena, Rockwell Automation. The main contribution of this work is the novel approach to designing travel time to the construction sites, improving its validity and allowing us to optimize the production and delivery program. Results obtained in this project were used in the decision making process regarding the effective use of capital in installed capacity while minimizing risk.
