Many years ago I operated the largest nationwide online DVD rental business in my country. Our warehousing evolved from alphabetical to numerical, with layout changes along the way. Eventually we handed the rearchiving of DVDs to the database itself and allowed it to allocate blocks of scanned in DVDs that were being returned. New content also was allocated by this system.
It was incredibly fun seeing things like cached new releases going straight to dispatch rather than going into the warehouse. Blocks of returning stock would be allocated to warehouse sections that had gaps that had the physical size of the block of DVDs that were being checked in.
Obviously, those empty areas were most commonly rotating stock, so over time the warehouse would become more active in areas, requiring a reallocation of stock to allow walking lanes for picking staff to not become congested. Fun times and all done on early Dell AXIMs with upgraded batteries, red laser scanners, and this new thing called wifi.

This isn't as "CPU-based" as I had hoped, just metaphorically taking the idea of Performance and Efficiency cores from the Core i5. The simulated warehouse has a Performance zone, with ground-level storage for items that are needed frequently, an Efficiency Zone, with high-density racks for low-frequency items, and a Shared Zone for mid-frequency items and overflow. The simulation showed that this idea worked best, but the paper doesn't investigate why.

No issue with your analysis, but it’s a bit odd to say the “idea of Performance and Efficiency cores” is from the Core i5.
First, the i5 is a tier in Intel’s product stack and doesn’t refer to any specific generation. Core iX series processors have existed since 2009 and have started using (general purpose) heterogeneous cores only fairly recently (2020).
Second, I think most would credit ARM’s big.LITTLE tech (introduced in 2011) for the increase in popularity of these types of heterogeneous (general purpose) cores on modern SoCs.

lol the person you're responding to literally quoted the paper:
> 3. CPU-Based Layout Methodology
> The CPU-based layout in Figure 1 is inspired by the structural logic of the Intel Core i5 series Processor, segmenting warehouse spaces into specialized zones
also jesus christ who cares - it's just a metaphor not stolen valor.
