Abstract

Manufacturing Execution Systems (MES) play an important role in production management. However, many MES are either not following the industry standard or not providing high flexibility for small and medium-sized enterprises (SMEs) that are interested in user-defined software and low-cost automation solutions. This paper presents an ISA95 based MES architecture, an open-source evolvable MES that follows an industry standard. It is specifically designed for production management (e.g., production scheduling and execution) in SMEs. We expand this work into three directions. Firstly, we follow the industry standard - ISA95 guideline to identify the key functionalities, activities, and objects of the MES. Secondly, we leverage a model-driven paradigm to show how to design the architecture and data model. To keep it open-source, a business platform Odoo is chosen as it provides various well-designed free ERP modules as a foundation for MES design. Finally, various advanced features of Aalborg University (AAU) MES are illustrated by using an example product assembly.
