The proliferation of smart factory practices introduces the fourth industrial revolution called<br>Industry 4.0. Industry 4.0 creates new challenges and the application of networked manufacturing systems is one<br>of the important features required to handle the systems in an efficient way by communicating and processing<br>information to each other. Distributed systems provide coordination to allow the global information to be<br>available for a better decision making and consequently achieving high efficiency. This connectivity helps for a<br>better decision making and therefore achieve high efficiency. However, the evaluation on the accuracy of global<br>information between different architectures of distributed systems (centralized systems and decentralized<br>systems) has little work mentioning in the state of current manufacturing systems under the conception of<br>Industry 4.0. As a result, this research will fill the gap by providing an accuracy of the decentralized system over<br>the centralized system together with their sensitivity analysis. In this study, the decentralized system is built<br>based on the concept of Epidemic protocols or Gossip-based protocols, while the centralized system is a simple<br>client-server. The epidemic protocol is a bio-inspired communication paradigm that imitates the behavior of<br>virus when the outbreak occurs in a community. The accuracy in both systems has been monitored by means of<br>simulations. The effects of message loss to the accuracy of centralized and decentralized systems are studied. By<br>comparing the system accuracy between both systems, it was found that the accuracy of the decentralized system<br>is generally more accurate when the system is used for a long period. The accuracy tends to be lower down<br>especially when the information is not completely distributed, while the accuracy of the centralized system<br>receives an excessive suffer from message loss.</p>}, number={43}, journal={GEOMATE Journal}, author={Poonpakdee.
