This paper puts forward a PASCAL simulation model to evaluate the performance of three access policy protocols for replicated files in distributed systems. The three protocols are: static majority consensus voting, dynamic voting and lexicographic dynamic voting. The main objective of these protocols is to ensure the consistency of data in replicated files of distributed systems. The results show that lexicographic dynamic voting performs better than majority consensus and dynamic voting for all cases under study. The dynamic voting outperformed the majority consensus voting when there are four or more copies; the reverse is true when there are three copies. Also, it is found that adding a fourth copy to a basic set of three under the majority consensus voting reduces file availability; whereas adding a fifth copy improves the availability.
