These systems support various areas of the company's activity. Typically, the ERP system is used to support accounting, financial and administrative departments. The APS system supports production planning and scheduling. On the other hand, MES class solutions are a tool dedicated to the production area. The ERP system also gives the possibility of integrating information from different departments and different systems (including APS and MES) into one database. However, this system usually does not have the ability to analyze information on an ongoing basis and does not allow for comprehensive control of production processes. For this purpose, the MES (Manufacturing Execution System) and APS (Advanced Planning & Scheduling) systems are used. The ERP system supported by MES integrates information about production events with HR and accounting information. Thanks to this, it provides a full range of real-time data on the status and parameters of production. This allows for a thorough analysis of production costs and profitability. The APS system is dedicated to managers and planners to optimize and plan production. The functionalities of this system enable the creation of optimal production plans, simulations of various production scenarios, and also enable reactions to failures or any changes in the production plan. The information contained in the APS system can be an information input for the MES class solution.
