What is a MES system?

A manufacturing execution systems — or manufacturing execution software (MES) — are dynamic information systems that monitor and control manufacturing operations and information flow on your shop floor.

In other words, a business system like MES helps to track and record the transformation of raw materials to finished goods on the shop floor. This allows manufacturers to control all activities and operations on their shop floor. An MES module aims to ensure the effective execution of production operations and improve output production.

Benefits of manufacturing execution systems

Manufacturing Execution Systems (MES) offers a wide range of short- and long-term benefits. So, what are the benefits of using MES software within your business:

1. Reduce costs 

MES manufacturing allows you to track costs in real-time from the shop floor, such as:

  • Labor
  • Downtime
  • Maintenance

Having this data at hand will help you to not only increase productivity but also minimize your manufacturing costs. A better understanding of where your costs are focused will help your business make informed decisions around identified saving opportunities.

2. Minimize inventory

You can reduce your carrying costs by having information to let you determine which raw material or finished goods you need to have on-hand and which inventory levels you can reduce. This allows your entire business to know how much inventory is available and what needs to be ordered from:

  • Purchasing
  • Shipping
  • Scheduling departments

3. Reduce waste

Easily identify inconsistencies or aberrations on your production lines, so you can immediately halt them to limit the number of faulty products or waste material that appears on the shop floor. MES systems help you achieve this through:

  • Full traceability of your raw materials, production, and fulfillment
  • More reliable and precise process planning
  • Make data-based operational and strategic decisions

4. Eliminate paperwork

It’s not just a dream. Paperless manufacturing is a reality. Adopting an MES software eliminates paperwork and manual data-entry processes from your daily operations. As you can see, MES manufacturing allows you to effortlessly improve your production efficiency.

How MES systems relate to other systems

Manufacturing Execution System (MES) systems help a product developer manage the actual manufacturing of a product and collect, store, and make production data available for the entire manufacturing process.

However, MES systems don’t exist in a vacuum. They are part of a complex system of levels that allow you to ensure that your manufacturing processes are optimized for maximum efficiency and productivity. Smart manufacturing is underpinned by the ISA-95, which is the international standard for developing an automated interface between enterprise and control systems, based upon the Purdue Reference Model for CIM (hierarchical form).

Within this, a manufacturing execution system is a level 3 system, otherwise known as a manufacturing operations management system (MOMS).

It can receive and send information to level 4 systems such as an ERP or MRP software, which are responsible for manufacturing planning and logistics. Level 1 and 2 systems control production processes, including continuous and discrete control, as well as batch automation systems to track production. Finally, level 0 refers to your physical manufacturing production at your shop floor level.

Having all these systems communicating and working together is vital to increase your productivity.

MES vs ERP: what’s the difference between MES and ERP?

  • ERP — Helps you manage and create your basic schedules for production, along with material use, your deliveries and shipments, and gathering information about your business
  • MES — Helps you manage your shop-floor manufacturing operations, as well as reporting on production line activities in real-time

Firstly, enterprise resource planning (ERP) is a tool used to manage:

  • Inventory
  • Order
  • Accounting
  • Human resources
  • Customer relationship management (CRM)

There might be some confusion between MES and ERP, but MES systems are basically the step between ERP and analyzing the performance of machinery and resources.

Though systems improve due to technology, the boundaries between the different software become blurred. There’s some overlap in MES vs ERP, as some ERPs on the market also perform similar MES manufacturing functions, such as batch inventory management.

Can MES work with your ERP or MRP?

So, if you’re already set up with an ERP or material requirements planning (MRP) system, the big question on every manufacturer’s lip, is can your MES work with your other systems?

If your system isn’t already performing the tasks that all three systems need to achieve, which some cloud-based manufacturing software do, here’s how MES systems can benefit your other software.

MES ERP

With your ERP tools, you can prepare your operations, from schedules to deliveries needed, and with your MES systems, you can monitor the progress of jobs from the floor level.

MES MRP

Firstly, MRP is software for handling your inventory, planning, and scheduling details. So, in the same manner, as MES and ERP systems, your MRP is going to help you prepare your inventory ready for production, and your MES will help you track your raw material consumption on the shop floor.

MES systems control scheduling directly on the shop floor

A manufacturing execution system will be one of the most important tools in your arsenal for controlling and managing your shop floor scheduling.

There can be a high level of variation on your shop floor so it presents a great opportunity for you to find areas of your manufacturing operations to optimize and improve production. Knowing the variations which can appear on the shop floor will allow you to use your MES manufacturing system to mitigate these issues. But what are MES shop floor variations?

Causes of variations on the shop floor

There are two types of shop floor variations in MES manufacturing:

Common cause

Common variations are a part of the process, such as natural wear and tear, old machinery breaking down, and other expected factors.

Special cause

Special variations are unexpected issues, like something external to your production lines. Special variations include:

  • An operator making a mistake
  • Parts breaking
  • Power outages

This is why SPC MES systems are perfect for observing the performances of your processes to predict, identify, and remove these sources of variations with:

Real-time data

Having a real-time overview allows you to detect problems immediately to make corrections and minimize faulty finished goods going into circulation.

Shop floor control rules

MES manufacturing allows you to detect out-of-control or non-random problems appearing by setting rules to highlight issues occurring on the shop floor.

Corrective actions

Once you have a system that can identify variations, you can then start implementing solutions, which can be things including:

  • Training staff
  • Process standardization
  • Refining your processes

So, that’s everything you need to know about what is MES. But, what is the perfect tool to help you get started on MES manufacturing?

Is a manufacturing execution system right for your business?

MES systems are especially important for industries that are regulated due to perishable inventory.

However, understanding how an MES system can benefit your business will depend on your business needs and what you want to achieve. This means that before choosing and using an MES system you need to ask yourself:

What does your business need?

Understanding your business’ strategic short- and long-term goals is vital before choosing to use any tools or systems. An MES system will enable you to improve your manufacturing operations – but what exactly are you looking to improve? Without a clear understanding of your goals, a management system will not bring you the benefits you seek. Spend time defining your goals and asking yourself what issues you want to solve.

Pain points solved

This brings us to the next consideration – what pain points can a MES system solve?

Identifying your manufacturing pain points will allow you to use the MES system you choose to solve them. This may be removing bottlenecks from your production by providing real-time updates of your inventory or optimizing your shop floor operations through product bill of materials (BOM) available from a shop floor app. Take a look at our benefits section for a full overview of how an MES system can help your business.

Available integrations

The whole purpose of MES implementations is to work within a manufacturing structure integrated with your other systems and tools to ensure full control of your logistics, operations, and production – with the view to constantly improving your processes.

That’s why you need to choose an MES that can be integrated with all the other tools and requirements your business has. Choose an MES software with seamless integration into an ERP solution or MRP system so that you can effortlessly manage and improve your manufacturing planning and logistics, shop floor control, as well as your manufacturing operations.
