Episode 1: Inventory – Initial mapping

Posted on: 9 June 2023

Welcome to TETRIS, the way to Factory 4.0!

In this first season, you’ll discover our 5-step roadmap for improving your plant’s environmental performance.
Here are the 5 steps:

Step 1 – Taking stock to prepare the ground.

Step 2 – Detailed analysis, where we explore your plant in depth.

Step 3 – Adjustments to optimize your plant’s performance.

Step 4 – Guidelines and master plan, to define and structure your ideal factory.

Step 5 – Continuous improvement to sustain your environmental performance.

In this 1st episode, we’re joined by Sébastien Papouin, Energy Technical Director and co-founder of Dametis. Hello Sébastien, can you introduce yourself in a few words?

Hello, my name is Sébastien Papouin and I’m Technical Director at Dametis. I have 25 years’ experience in industrial energy efficiency.

OK, great, thanks Sébastien! So, today, we’re starting with the very first step to take when you want to improve your plant’s environmental performance. This first sub-step is called initial mapping. But before we get to the heart of the matter, you’re going to tell us about the Lego theory.

So, as a preamble, I wanted to tell you about the lego theory. Each plant is made up of the same blocks, be they pumps, compressors, refrigeration machines, cooling towers and other equipment that will quickly be found in all plants, but no two plants are the same. It’s exactly the same with Lego: you give 2 identical boxes of Lego to 2 children, and they’ll build you a different object, so it’s exactly the same with factories. In fact, they are all composed of the same elementary bricks, yet no two are alike. The idea for us, then, is to deconstruct our factories to arrive at elements that are comparable from one factory to another.

Before you can improve your plant’s performance, you need to know where you’re starting from and what you’re aiming for. This theory makes it possible to define a standardized transverse frame of reference for comparing plants with each other, block by block. Each block will contain its own business rules and data. I’ll leave it to Sébastien to define the initial cartography.

The initial mapping involves taking a plan of our plant and positioning the various production workshops, warehouses and utilities on this plan, whether steam, compressed air, refrigeration or other utilities or processes, in order to visualize our initial block, which is the plant in its various blocks and sub-blocks.
The idea is for this mapping to become a standard for you, i.e. when an auditor, for example an external auditor, comes to audit your plant, whether it’s an energy audit or something else, he or she should do so on the basis of this mapping that you have standardized.

Sébastien, what are the prerequisites for mapping and how long does it take?

I’d say that the prerequisites for mapping are as simple as drawing a floor plan of the factory and dividing it up into the various blocks we want to list in our factory. In half an hour or an hour, the exercise is completed.

Do all manufacturers carry out initial mapping?

It’s not a standardized step for manufacturers, who know their plant but haven’t necessarily done the mapping. Some of them have, I’d say around 30% of manufacturers have done this mapping. When you arrive at a factory and ask for a floor plan of the plant, you can already see this mapping visible on the floor plan.

Can you tell us who’s doing the initial mapping? How are things coordinated between the different teams?

This mapping is a consensus between all the plant’s departments (main departments) to agree on the standardization and mapping of its plant.

What are the difficulties of mapping? What are the pitfalls to avoid?

What’s hard about it? Perhaps it’s a question of simplifying your plant, especially when you have a complex plant with intersecting processes or process lines. This mapping must remain relatively simple, and the pitfall would be to go into too much detail and have a map that becomes unreadable.

This mapping is the starting point for any plant analysis, whether it’s an energy audit or some other kind of audit, and will be used to contextualize the data.

In a nutshell

Initial mapping involves dividing a plant into blocks. This breakdown into blocks becomes your standard to impose when an external or internal player comes to analyze your plant.

Initial mapping gives you a synthetic, global view of all your plant’s processes and flows.

It allows you to:

1. Visualize all plant components, from raw materials to finished products, processes and utilities.
2. Finally, it lays the foundations for defining THE standard for your plant.

In short, initial mapping is the starting point for your industrial environmental transition.
