Definition: Manufacturing Execution Systems
What is a Manufacturing Execution System?
Lets start off with a simple definition:
A manufacturing execution system (MES) is an online integrated computerized system
that is the accumalation of the methods and tools used to accomplish production.

Classic Manufacturing
Classic Manufacturing can be described by the following characteristics:
- Large number of disconnected systems, resulting in:
- Tardy data
- Inaccurate and unreliable data
- Information is hard to access and not trasparent
- Information difficult to analyze
How MES is changing classic Manufacturing
In general the implementation of MES will not change your production methods or
manufacturing processes. It will just provide you with more timely and accurate
information so that you can make better, well informed decesions that will improve
your bottom line.
An MES can proabably be best defined by a number of integrated capabilities that
will help you out to accomplish production:
- Document Control Will take care that required document is available a the
point of use. This can include: Work Instruction, Specifications and Drawings, Recipies,
Maintenance Manuals
- Record Control
- Product Tracking and Genealogy
- Maintenance Management
- Data Collection/Acquisition
- Quality Management
- Resource Allocation
EZ-MES is providing you with the following Core Functions:
- Planning System
- Work Order Management
- Equipment Management
- Inventory Management
- Material Movement Management
- Data Collection
- Exception Management
Definitions for Manufacturing Execution Systems (MES)
A production scheduling and tracking system used to analyze and report resource
availability and status, schedule and update orders, collect detailed execution
data such as material usage, labor usage, process parameters, order and equipment
status, and other critical information. It accesses bill of material, routing and
other data from the base ERP system and is typically the system used for real-time
shop floor reporting and monitoring that feeds activity data back to the base system.

Computerized system used in real time documenting, controlling, and management of
an entire manufacturing process that includes machines, personnel, and support services.
MES applications track activities and resources, link administration to the shop-floor
activities, and are often integrated with other applications (such as MRP II) used
in purchasing, shipping-receiving, inventory control, and maintenance and scheduling.
