Manufacturing execution systems (MES) are computerized systems used in
manufacturing, to track and document the transformation of raw materials to finished
goods. MES can provide the right information at the right time and show the
manufacturing decision maker "how the current conditions on the plant floor can be
optimized to improve production output."[1] MES work in real time to enable the
control of multiple elements of the production process (e.g. inputs, personnel,
machines and support services).
MES may operate across multiple function areas, for example: management of
product definitions across the product life-cycle, resource scheduling, order execution
and dispatch, production analysis and downtime management for Overall Equipment
Effectiveness (OEE), Product Quality, or materials track and trace. MES creates the
"as-built" record, capturing the data, processes and outcomes of the manufacturing
process. This can be especially important in regulated industries, such as food and
beverage or pharmaceutical, where documentation and proof of processes, events and
actions may be required.
The idea of MES might be seen as an intermediate step between, on the one hand, an
Enterprise Resource Planning (ERP) system, and a Supervisory Control and Data
Acquisition (SCADA) or process control system on the other; although historically,
exact boundaries have fluctuated. Industry groups such as MESA International–
Manufacturing Enterprise Solutions Association were created in the early 1990's in
order to address the complexity, and advice on execution, of MES Systems
