What is the Manufacturing Execution System? (Benefits + Architecture)

While market demand pressurizes manufacturers to improve production efficiencies every day, the manufacturing execution system provides a smart structure for real output execution. Factors like reducing scrap, increasing uptime, and lower costs are the topmost reasons why the MES software market is set to hit $24,344 million by 2025.

Of course, COVID-19 is another factor that you can’t ignore. It turns out to be an accelerator for digitization in many fields that had slowed down before. So, those manufacturers who have already extended digital capabilities to support remote operations have fared better than others. Do you also need to digitize your operation to avoid disruption in the future? Let’s get started with a strategy for your on-premise manufacturing solutions.

What is the Manufacturing Execution System (MES)?

Manufacturing execution system (MES) is an information system that connects, records, and manages the factory floor of dynamic manufacturing processes and data flows. The primary objective of an MES is to ensure the successful execution of manufacturing activitieS and to increase production performance.

A standard MES provides customized data on the manufacturing lifecycle, starting with the release of orders until the finished goods distribution point of the commodity. Like any piece of software, a production solution also comes with a whole bunch of functions, benefits, and workflow that helps business goals. So let’s start with your interest first which is the advantages of a manufacturing information system.

Manufacturing Execution System Architecture

By now, you would have an idea that an MES solution is nothing but an information model created by the manufacturing enterprise solutions association (MESA). That generally divides the production system into 3 levels. Here’s the MES architecture in the following table.

Manufacturing Execution System Architecture

  • Level-1: Describes the role of the ERP software for business planning and logistics which includes the establishment of a basic plant schedule and time frame for production, material use, delivery, and shipping.
  • Level-2: Describes manufacturing operations management handled by MES that includes a detailed workflow for manufacturing the desired end products. The team also maintains the records and optimizes the production process.
  • Level-3: Defines the manufacturing control system where you monitor and automate the control process of production from work in progress to output. It includes basic control, supervisory control, process sensing, and process manipulation.

What makes the MES framework relevant is that it acts as a practical layer between the ERP and the shop floor process control systems (execution system), offering clarity, consistency, and insight into the real-time workflow.

  2. Resource Allocation and Status

    As part of the method routing concept, the MES systems list the resource specifications for each manufacturing execution job. It is then moved to the method of ERP or scheduling software solution. This lets you define and monitor the status of your assets and how they are used in the manufacturing process. Manufacturing organizations can handle the allocation and status of resources including equipment, tools, materials, and labor.

  3. Dispatching Production Unit

    Dispatch function is focused on enterprise resource planning (ERP) global guidance tailored to the availability of services, scheduling specifications, and capability. To control the bidirectional flow of output data between the ERP and the workshop in real-time, the manufacturing execution guarantees that output data is still precise, accurate, and up-to-date.

  4. Performance Analysis

    This manufacturing execution software feature helps you to understand how the manufacturing process functions and how it might be expanded. Businesses can define and record key performance indicators (KPIs), conduct predictive production performance analysis, deliver performance tracking, and monitor dashboard displays and datasets.

  5. Maintenance Management

    To minimize downtime and production output interruptions, preventive system maintenance as part of MES can be scheduled more quickly and effectively. To reduce the effect on plant activities, companies can improve the preparation of preventive maintenance practices. Just plan for inevitable repairs without hindering performance, and allow for a seamless flow of production.

  6. Process Management

    One of the important functions of the manufacturing execution process is to manage the production process, including guided work phases and work orders, from order release to work in process (WIP) to finished products. Therefore, manufacturing systems offer support with process routing and operational sequencing to provide complete traceability of output.

  7. Quality Management

    You may incorporate this feature directly into the MES system or use external software to overcome regulatory compliance. Integrated quality control in the manufacturing process assists you in the workflows of corrective and preventive action (CAPA), verification, and non-conformance.

  8. Data Collection/Acquisition

    You may call this feature the heart of the MES systems as it enables the input of all information, manually or automatically. You can monitor and accumulate important details and, when you need it, retrieve the data quickly. Just collect and store data from end-users, accounts, or computers, on databases or embedded historians.

  9. Product Tracking and Genealogy

    With this execution system function, you can track each object in the manufacturing process, unique recognition of parts and components, as well as the equipment and workers involved in handling it. Then, from the raw material to the product assembly, you may group final parts or lots with all their corresponding manufacturing execution details.

  10. Labor Management

    Production execution systems let you control and use the highest productivity and attributes of workers and services in the most desirable places as you automate manpower. Handle the employees, objects, & activities and monitor the skills they require. This means that, at each stage of the manufacturing execution process, you always have the right people in charge.

  11. Document Control

    Manufacturing execution systems also provide the operators with a quick way to view substantial records as they need them, including manuals, drawings, and notes. This saves time for you and your team by not having to dig for the details you need across file cabinets.
