MES (Manufacturing Execution System) is intended for managing and tracking operative functions in production and for relaying information between different systems and production automation. According to our experience, LeanwareMES improves throughput by 30 % and reduces the amount of necessary corrections by 20 %.
Single user interface for manufacturing
The LeanwareMES interface displays the necessary information at the right point of the manufacturing process in real time. The system differs from conventional manufacturing execution systems, as it only provides the employee with the information they need for the task at hand. MES reduces the number of systems needed in manufacturing and production workers only have to monitor a single screen. LeanwareMES directs and assists the production worker at the work station, so there is no need to leave the station. This increases work efficiency.
Real-time transparency in manufacturing
All manufacturing activities are acknowledged in MES minute-by-minute, which allows accurate visualization of the production status. This enables quick reaction times and 100 % traceability. Archiving manufacturing activities also allows analytics and continuous improvement.
The right information and materials are at the right place at the right time
In addition to guiding the worker, LeanwareMES also directs automation and material flows. A production order is released from the ERP system to the MES, where it is broken down to tasks for each work phase and the materials to be consumed. LeanwareMES knows where unfinished and intermediate goods are located. This means that a production worker can focus on his/her job and always have the right amount of materials at the work station without having to search for them all over the plant.
Why LeanwareMES in addition to ERP?
ERP = Enterprise Resource Planning
Improved visibility of manufacturing activities allows the information to be used for management and continuous improvement. ERP processes months, weeks or days and MES processes hours, minutes, seconds or fractions of seconds.
|Work management||ERP answers the questions ‘when, how much, and what type?’ |
ERP stands for ‘Enterprise resource planning’ → ERP is essentially a planning system for the company.
|MES answers the questions ‘how is the job to be done, how is it progressing, was it successful, and who performed the work?’ When compared to a planning system (ERP), MES is an environment that manages work and provides instructions
MES stands for ‘Manufacturing execution system’.
|Usability and difficulty in learning how to use||A typical ERP interface includes tables and menu hierarchies that are difficult to use. ERP systems are fundamentally transaction-based systems, which means individually accessible commands that are used to execute tasks.||LeanwareMES is easy to use on touchscreens. MES is fundamentally process software. The process is defined that the system is to follow and provide instructions to the user. The user does not have to remember what is to be done next; the system will provide the information and the reminders.|
|Manufacturing perspective||ERP includes functions from all areas of the company. It is universally applicable software and reports across functions. The generic software without customization is effective only in the most basic of environments. This also results in a challenge, as customization often spreads to all areas and may risk the operation of the entire system. Customization may also prevent the adoption of new, updated versions of the software and put the entire ERP system at risk.||MES only includes the functions essential for manufacturing and they can be customized to fit the company environment without exposure to risk.|
|Accuracy||The typical time-scale in an ERP system is a month, week or day.||The typical time-scale in a MES is an hour, minute, second or even fractions of a second.|
|Timing accuracy and work management||Production workers search information from the ERP themselves.||MES displays the exact information needed for completing the work (e.g. work instructions or change notifications associated with a specific work phase).|
|Automation and machinery integration||According to the ISA-95 standard and other reasons associated with general support, an ERP system should not be connected with automation if it can be avoided. Real-time management is not intended for the ERP level.||The ISA-95 standard defines the levels for managing manufacturing and MES/MOM is a part of automation. Machinery management and logic can also be defined on the MES level.
MES relays detailed production information to automation and machinery and receives the data from automation and the machinery (e.g. quantity of completed units).
Details important to manufacturing, such as production line and machine-specific parameters, can be maintained in MES.
|Logistics||Materials and intermediate goods are located 'somewhere in the manufacturing area’ in an ERP system. WM functions are available as expansion modules to ERP systems, but they rarely work seamlessly for production materials.||MES knows the buffer stocks before work phases and is able to seamlessly communicate with the WMS when necessary.|
|Traceability||ERP offers basic traceability. Who acknowledged the order as completed and what materials are planned for the order.||MES offers detailed traceability on used materials and resources, measurement results, timestamps and people - even the versions of the used instructions. Detailed traceability is often required by law.|
|Specificity to plant||ERP is a global system, which is often expensive and difficult to customize.||MES is a local system, which allows for plant-specific flexibility.|
What is the difference between MES and APS systems?
APS = Advanced Planning Scheduling
- MES is a system meant for managing, executing and documenting manufacturing, while APS is a system meant for planning and simulating production loads (Planning and Scheduling).
- Handling manufacturing management and execution without a MES does not allow for exception reporting, work instructions or material requests. Traceability is also often insufficient (e.g. serial and lot numbers of raw materials associated with a product).
- TPlanning production without an APS system does not allow for modeling ‘what if’ scenarios.
We follow the ISA-95 standard
ISA-95 is an international standard that describes the principles and concepts of manufacturing systems. The standard is intended to be applied to all manufacturing industries. LeanwareMES follows the principles of the standard.
