01. Operations and Process Management
Today, in times which Industry 4.0 (I4.0) technologies are dominating the industry trends, there are many software solutions at the market that promotes to digitally transform systems and its processes. Particularly in the level in which communication and information technologies (ICTs) impact the most, some solutions such manufacturing execution systems (MES) are considered backbone in this modern concept of digitally-driven manufacture. However, because the MES is such an all-encompassing system, its implementation involves balance the interests of stakeholders from across the company. Even the most agile manufacturers will need to halt specialists and spend months reviewing the scope of their MES-level needs. Because of this, many times and already functional MES become a legacy system, as it promotes integrating data from various aspects of the manufacturing process, giving them long-living characteristics. And more, it is clear the existence of functions overlaps regarding the ISA95 MES-level standards and software solutions on the market. Many propose enterprise resource planning (ERP) functionalities aggregated directly with shop-floor systems. Looking to clarify the gap between literature, to cite ISA95, and software vendors in the present scenario, our research intends to ease (firstly) the understanding of MES within I4.0 vision, and (secondly) how solutions can be perceived regarding modern MES (long-term solution) or already implemented legacy systems that may already contain the functions necessary to a short-term modernization strategy.
