What is HMLV Anyway?
Sometimes you may see High-mix/Low-volume Manufacturing (HMLV) mentioned as ‘Make to order’ manufacturing. That is not an entirely true comparison, however. You could be a HMLV manufacturer and still ‘Make to stock’. But in Food Manufacturing basically everything is made for orders, also Low-mix/High-volume productions.
In essence, HMLV involves many processes and/or changeovers on the production line during a shift to produce a wider array of SKUs and products – either different products altogether or variants of one product. There is no clear definition of how many changes that are involved to be considered a HMLV manufacturer.
We consider Ready-meal manufacturing as HMLV in most cases, as there are many processes involved and a plant rarely produces one product only. However, Meat Manufacturing is also increasing their mix when outputting their products in many different weight ratios and cuts. Therefore, these could also be considered HMLV producers – especially if their variants and products involve a lot of manual processes holding them back from producing higher volumes cost-efficiently.
HMLV production setups adapts to changing demands and is very agile and flexible. Alas, this flexibility comes with a cost as it is often done manually. We will argue that when the complexity reaches a point where it would seem automation is largely not possible, it should be considered a HMLV manufacturer.
The flexibility needed to adapt should be implied and expected from all technical equipment henceforth.
