Empty Shelves? – Understanding Supply Chains, Logistics, and Recovery Efforts…

Empty Shelves? – Understanding Supply Chains, Logistics, and Recovery Efforts…

Posted on by

By now everyone is familiar with the abundant pictures on social media of empty shelves in local stores.  Having some familiarity with the supply chain might help people to understand some of the challenges; and possibly help locate product. (Pics from Twitter)

There are essentially two types of distribution centers within the retail supply chain for most chain markets, food stores and supermarkets.  The first type is a third party, or brokered, distribution network.  The second type is a proprietary, company owned, distribution center.  Knowing the type of distribution helps to understand what you can expect.

If your local retail store is being replenished from a third party distribution center, you can expect greater shortages and longer replenishment times; we will see entire days of empty shelves in these stores.  However, if your local retail store owns their own warehouse and distribution network, the replenishment will be faster.  In times of rapid sales, there is a stark difference.

These are general guidelines: An average non-perishable distribution center will replenish approximately 60 stores.   Those 60 stores will generally not extend beyond 100 miles from the distribution center.  The typical company owned warehouse will have approximately 20 tractors (the semis) delivering trailers of goods to those sixty stores.

In this type of network… On a typical day a truck driver will run three loads. Run #1 Delivery-Return; Run #2 Delivery-return, Run #3 Delivery Return. End shift.

If every tractor is operating that’s a maximum capacity of 60 trailers of merchandise per day.  Many stores receiving more than one full trailer.

A typical store, during a non-emergency, will receive 1 full trailer of non-perishable goods three to five times per week.  However, under current volume the purchased amount of product is more than triple normal volume.  It is impossible to ship 180 trailers of merchandise daily to sixty stores with 20 fixed asset tractors.  This is where the supply chains and logistics are simply incapable of keeping up with demand.

Thinking about distribution to a 100 mile radius.  The stores closest to the distribution center will be delivered first, usually overnight or very early morning (run #1). The intermediate stores (50 miles) will be delivered second, mid-morning (run #2).  The stores furthest from the distribution center will be delivered third, late afternoon (run #3).

So if you live close to a distribution center, your best bet is early morning.  If you live in the intermediate zone, late morning to noon.  If you are in the distant zone in the evening.

The current problem is not similar to a holiday, snow event or hurricane. In each of those events typical store sales will double; however, during holidays or traditional emergencies the increase in product(s) sold is very specific: (a) holiday product spikes on specific items are known well in advance and front-loaded; and (b) snow/hurricanes again see very specific types of merchandise spikes, with predictability.

In the current emergency shopping pattern the total business increase is more than triple, that’s approximately 30% more than during peak holiday shopping.  Think of how busy your local store is on December 23rd of every year.  Keep in mind those customers are all purchasing the same or similar products.  Now add another 30%+ to that volume and realize the increases are not specific products, everything is selling wall-to-wall.

Perishable and non perishable products are selling triple normal volume.  This creates a replenishment or recovery cycle that is impossible to keep up with.  The first issue is simply logistics and infrastructure: ie. warehouse (selectors, loaders), and distribution (tractors, trailers, drivers).  The second issue is magnifying the first, totality of volume.

A hurricane event is typically a 4 or 5 day cycle.  A snow event might be 2 days.  The holiday pattern is roughly a week and all the products are well known.  However, the type of purchasing with coronavirus shopping is daily, everything, with no end date.

Once the store is wiped out, a full non-perishable recovery order might take four tractor-trailers of merchandise. In our common example, if every store needed a full recovery order that would be 240 tractor-trailers (60 stores x 4 per store).   This would need to happen every day, seven days a week, for the duration of the increase.  [And that is just for the non perishable goods]

That amount of increase is a logistical impossibility because: (a) no warehouse can hold four times the amount of product from normal distribution; (b) the inbound supply-chain orders to fill the distribution center cannot simply increase four fold; and (c) even with leased/contracted drivers doubling the amount of tractors and trailers, there’s still no way to distribute that much product.

Instead what we see are priorities being assigned to specific types of product that can be shipped to maximize “cube space” in outbound trailers going to stores.   A distribution center can send 100 cases of canned goods (one pallet) in the same space as 15 cases of paper towels or toilet tissue (one pallet).  So decisions about what products to ship have to be prioritized.

Club stores (ex. BJ’s, SAM’s, or Costco) can ship bulk paper goods faster because they do not carry a full variety of non-perishable items.  The limited selection in Club stores naturally helps them replenish; they carry less variety.  Meanwhile the typical supermarket distribution center has to make decisions on what specific goods to prioritize.

Nationally (and regionally) the coronavirus shopping panic is far outpacing the supply chain of every retailer.  Instead of a weeks worth of food products, people are now trying to purchase a months worth.  Every one day of coronavirus sales is equal to three or four normal days.

To try and get a handle on this level of volume we will likely see changes in operating hours.  Expect to see stores closing early or limiting the amount of time they are open every day…. the reason is simple: (1) they don’t have the products to sell over their normal business hours; and (2) they need to move more labor into a more compact time-frame to deal with the increases in volume.

Okay, not particularly well-written imho, but with a little careful reading and a little head-scratching it should help you get to your preferred store exactly when you should be there in order to avoid the empty shelves.

I would think a small percentage of the population hoards TP for a virus situation, so the tissue issue should not be on going. They have their stash.

I guess that’s why we are running out of toilet paper, too. Goodness!

Thanks for your to me excellent write up, it explains a lot and also tells us why the President removed boundaries for other truckers to ship things that they do not normally or add to the capacity to do so.

Additionally as you said if you look at a disty warehouse they only have so much quantity on hand before their restock level kicks in and suffers from a lag in that link between them and the next link in the chain.

Amazon builds million SqFt warehouses for a reason and typically they are co located to Railroad service versus air freight as the volume is larger per rail car and there is no need to have a truck in between that source and the warehouse which crimps the hose as it were and slows the flow of goods (water)

I have always kept a stash of TP since riding out several blizzards while living in Michigan. I’m good. Did not need to participate in any TP riots.

I think 4 trucks for a recovery is really optimistic. 4 general merchandise trucks maybe but to cover meat, produce, deli and dairy you would need a few more.

The last paragraph appears to be generally consistent with what I’m seeing in my area, in both local chain stores and Sam’s Club.

You have to think that panic buying will end soon. The refrigerator can only hold so much. Non-perishable foods can be stored in odd places but most people have a budget that they can’t squeeze much more out of for grocery items.

In other words, Scotty’s words of Captain, we’re giving it all she’s got, are in play.

There are only so many trucks, so many truck drivers, so many feet of warehouse, so many shelf stockers, so many hours in a day.

If everyone would just grab one pack of TP, this system stress would not occur.

There is, I suppose, a small upside to this panic buying. With the empty shelves, a lot of areas get a cleaning that they haven’t had in I don’t want to think about how long!

And the stores have sold off a lot of “extra” stock that ends up being tossed, which helps the landfills.

It’s a good piece, but it only focuses on the distribution end of the supply chain. Even if the distribution process was fully capable of delivering 40% more product to the end user tomorrow, there’s always the problem of producing it all fast enough to match the delivery process.

Think of a supply chain as a series of conveyor belts. You can make one belt bigger and operate it faster, but that doesn’t help unless the entire series of belts can process the materials at the same rate.

I've gotten in the habit of hoarding things over the year, because in my business it is hard to predict what my income will be from quarter to quarter.

There are lots of things you can safely hoard, if you have space. Cleaning supplies of all kinds, olive oil, aluminum foil, canned soup (I have a lot of that). Not to mention warm socks, beef stock, tomato paste, pasta, etc.

The only problem is that any time my wife feels the need to give someone a present (like because they gave her a present and she hadn't gotten anything for them) she just treats my pantry like a store, and grabs anything in sight. Once one person in a group of five gave her a present, so she handed out my entire supply of warm socks to the whole group because she didn't want to just give a gift to the one person who gave her one.

I wish I could find that old sound bite of some logistics officer during a post Katrina news conference saying something along the lines of people watching too much Star Trek, in that we can’t push a button and supplies materialize out of thin air.

Part of the problem is that most people are used to eating out. Now the stores need even more food to support the increased demand caused by people buying more food than normal from a grocery store in order to cook at home.

This is why Aldi stocks their stores with a limited assortment. The Albrecht brothers figured that out after WW II when we had bombed most of the German infrastructure into rubble. Limited selection = quicker, more efficient restocking.

This is why Trump told the governors do NOT close fast-food drive thrus.

Heh, finally a topic Mark “Sundance” Bradman the former Publix produce department manager actually knows something about.
