Abstract
Manufacturing Execution System (MES) plays an important role in supporting small and medium-sized enterprises (SMEs) for their daily production operations. SMEs’ businesses traditionally rely on paper based system of operations. With the rapid increase in technology, it is almost guaranteed that this will be replaced by more efficient and reliable smart MES. This paper presents a RFID enabled real-time manufacturing system which will incorporate five functions. These five functions will be integrated into an android based interface which reads and writes data to a cloud based database in real time. NFC technology is also utilized to improve the ease of use. This aims to promote communication within a company, improve product quality, optimize data storage and reduce paper waste. A case study demonstrates the feasibility and practicality of the designed and developed system.
Key Services
RFID middleware is one of the most important features of the MES. It is responsible for services that manage raw data as well as inter-device communication. Two key functionalities are associated with this service – data collection/acquisition and maintenance management. The latter will not be discussed in this paper as it is not yet implemented. Data collection is essential to the proper implementation of manufacturing execution systems. Traditional paper-based style of operations, are often error prone and unable to cope with dynamic shop-floors, among other things. These problems arise mainly due to the untimely gathering of information which can be achieved through proper deployment of RFID enabled smart devices such as workers, machines and resources. Figure 1 shows how the smartphone app bridges the connection gap between the RFID devices and the cloud MES. Appropriate usage of this at key stages, would enable data to be frequently updated, allowing location and status, among other things, to be known. Once this data is collected, it is organized into information that can be used so that appropriate feedback can be sent back. Due to the nature of RFID many security measures need to be put in place to prevent the loss of any data.
