Currently, the marketing strategy in the manufacturing industry is becoming more and more competitive. Thus, the production efficiency becomes the main developing trend, which many people are now pursuing. However, the automatic production might cause resource conflicts and system deadlocks. In this study, Petri net models and analysis were used to effectively avoid deadlocks and to achieve the goal of lean production. The iPhone XS device developed by Apple is now a popular product. Consequently, this paper aims to describe its manufacturing system by using Petri net models. Meanwhile, the siphon property of Petri nets can be used to detect the deadlock in the manufacturing processes and to avoid it from occurring. Two simulation software tools, WoPeD and PIPE, were applied to conduct the experiments. The experimental results have indicated that our proposed approach is more feasible and acceptable than other existing ones.
