This paper reports on the results of a prototype simulation model development for Enterprise Simulation for Precast Operations. The project aims to provide a flight simulator like tool to the precasters that would encapsulate technical and operational aspects of precast concrete production to help them study cost and schedule tradeoffs and identify effects of different concrete mix designs on production process. The project has been divided into two areas i.e. technical simulation and operational simulation of precast production operations. This paper reports only on the operational model. The model is used for demonstration of proof of concepts and as a knowledge elicitation tool with the industrial partners. The report reflects on process of model development, objectives of prototype, and how closely those objectives have been met.
