As industry becomes increasingly capital intensive, and the relative cost of assets increases, so does the importance of utilising and maintaining these assets. This tendency is particularly true for industries with continuous process. Here, both the economic, safety, and the environmental consequences of equipment failure can be enormous. The increasing complexity of the equipment also has a profound influence on its productivity, maintenance and process improvement. This Paper investigates the use of computer simulation for evaluating the performance of Cement Production in Libda cement factory in Libya and to investigate design modification to enhance its productivity. The results indicate that simulation could provide a useful tool for critical evaluation of factories and to plan design and modification activities
