Information Requirements to Develop an MES (Manufacturing Execution Systems)
Regarding the information requirements and/or specifications that are needed to size and determine the scope of an automation project to implement an MES, it must be defined if the application and/or industry requires the following.
- Compliance with the ISA-95 standard applicable to the Information Interaction for Manufacturing from the Floor to the ERP through the MES.
- Compliance with FDA/cGAMP5/CFR21-Part 11 & NOM-059.
- Interactive Analysis Tools.
- Personal Information Panels.
Data Required to Determine the Functional Scope of the MES Production System.
Scheduling.- Planning and Monitoring of the Production in Real Time WIP (Work In Process)
OEE Downtime (OEE-DT).- (Overall Equipment Effectiveness – Down Time). Real time Production Efficiency Monitoring.
Track & Trace.- Registration and Tracking. Genealogical tree to track and record Finished, Semi/finished, Raw Material, Operators, Equipment, Cells, Lines, and more, for the EBR (Electronic Batch Record).
SPC (Statistical Process Control).- Collect and Monitor Data for Statistical Process Control.
Recipe / Changeover.- Manage and Monitor Recipes and Format Changes.
MES Enterprise Module.- Analysis of Production Data and Centralized Reports for Multiple Plants and Production Lines.
Instrument Interface.- Acquire and Decode data of Scales, Gauges, Analyzers, Laboratory Equipment, and more.
Visual Web Service.- Communicates other systems such as ERPs, LABs, WMS and others that use Web services.
The MES Traking Points, support tracking data for any combination of MES modules including Track & Trace, OEE Downtime, SPC y Recipe. Any data that needs to be tracked requires an MES Tracking Point and represents a physical or virtual machine, storage location, work cell, production lie, work station, etc.
Examples of what an MES Tracking Point requires:
- OEE o DT for a line
- OEE o DT for a single-line machine
- Data for SPC in a storage silo
- Track & Trace in a collection site
- Recipe in a machine
- Track & Trace in a production line
- Track & Trace in a work cell
- OEE, SPC y Track & Trace in one line
- Track & Trace y SPC in a silo
- Track & Trace in a warehouse storage location
With the above we can indentify-qualify and quantify the number of MES Tracking Point
Data Required to Determine the Size of the Production MES
- Number of Physical Work Cells
- Number of Virtula Work Cells
- Number of Production Lines
- Types of Production Equipment
- Number of Production Equipment by Type
- Types of Operators by Product/Cell/Line/Plant
- Number of Operators by Product/Cell/Line/Plant
- Number of Users of the MES System
- Model/Brand/Specifications of the controller(s) of the cell(s)/ Production Line(s)
- Plant diagram (layout) with ID of Cells/Equipment/Lines/Plants
- Communications Network Architecture: Means and Protocols (physical-software) within the Plant
- Type of Products
- Number of Products
- Number of Product Formats
- Number of Recipes
- Customizations (conenections, screens, special functions)
