This web page should show general components and processes in a MES (Manufacturing Execution System). Based on an essential components of data exchange should the „Femto-MES“ established.
Correspondingly to the guideline „VDI-5600“, a MES can separate in the following Components: Order Processing, Detailed Scheduling and Process Control, Equipment Management, Material Management, Personnel Management, Data Acquisition, Performance Analysis, Quality Management, Information Management, Energy Management. Each component is connect to each other.
To let a MES running, the system needs to exchange data. The first step could be a order taking. Following with a material order as the result and the receiving materials. The material will be process with a recipe. This process generating and exchange data. The guideline „VDI-5600“ described structure and content of data flow. There are data for product, several processes, resources, orders and general data structure. Additional each management area has to process their own data, which are collected for analyses to key data and Key Performance Indicators, specified in VDMA 66412. In this zone, the MES supports the ERP directly and there isn't a clear border.
For a manufacturing of product their processes are relevant. The guideline „VDI-5600“ recommend to separate processes for status, for control, for a message and parameters.
A process in work has difference status, like queuing, preparing, processing and completed.
A status of control refer to the process in work and should prevent to cross limits of parameters. A message should inform about important process changes and an error. A status of process in work, a status of control, and process messages are transfer in process parameter, status parameter, parameter for errors and general data. The guideline „VDI-5600“ prefer process parameter targets and process parameter results.
There are additional parameters, which record working process resources, like time, material and energy.
The collection of all parameter from a working process are essential for actualise an analyse, a correction of process and for monitoring the efficiency and effectivity.
