A Supply Chain “Immune System”​

A supply chain is an organization composed of many different individual companies that each have their own businesses yet all work together to make and deliver products to different markets and customers. It’s one thing to talk about securing the operations of a single company, but what about a whole group of companies? How do we provide security – both cyber and physical – to a whole supply chain?

At dinner the other night my friend Wyly Wade and his wife Ka Murali and I got to talking and we thought maybe the human immune system would be a good model to use for protecting supply chains because the human body is an organization of many different individual cells, and the immune system protects all the different cells in our body. Maybe we could use that model to discuss how a supply chain immune system would work. We researched the idea and added more detail. We thought about ancient supply chains and modern supply chains. Immune systems seem to be a good way to discuss supply chain security… the idea is posted on Wyly’s cyber-security company website, Biometrica https://biometrica.com/why-supply-chain-immune-systems-are-needed-to-be-secure-in-the-virtual-world-and-the-physical

Operation Inherent Rescue – Humanitarian Supply Chains in Action

Imagine there is suddenly a real opportunity to stop the fighting in Syria. After months of tense negotiations and years of carnage, all the parties reach an agreement. But unless this agreement is implemented quickly it will collapse into chaos once again. The diplomats and politicians have reached agreement on strategy, now they need professionals to make it happen. And that means logistics and supply chains to support the movement of 500,000 refugees. Immediately.

SITUATION REPORT:  The UN Security Council has approved the Munich Security Conference recommendation previously endorsed by the 17-nation International Syria Support Group. In this UN Security Council resolution, a Chapter VII Peace Enforcement mission is authorized with participant nations committing Peace Keeping (PK) forces as part of the approved Peace Support Operation (PSO). The mission has been assigned the code name “Inherent Rescue”.

Simulations Create a Winning Supply Chain

Gonzalo Florez-Giraldo is working on his degree in global supply chain management and logistics at Houston Community College. A degree in supply chain management opens up a lot of opportunities, because Houston is a hub of commerce with its busy seaport and its location at the center of a transportation network serving much of the Southeastern and Midwestern United States and parts of Mexico.

Using supply chain simulations Gonzalo won first place in an internal contest at Houston Community College, and went on to represent the college in a city-wide contest titled “Houston Logistics Talent Show 2016’, organized by the CSCMP Houston Roundtable (Council of Supply Chain Management Professionals). The contest was an opportunity for innovative and entrepreneurial students at colleges and universities in the Houston area to present their ideas and show how they could improve supply chain operations.

Coming of the Real-Time Economy (and Pizza Delivery Supply Chains)

The other day I was indulging in one of my favorite ways to waste time online. I was exploring in Google Maps with the satellite view turned on. I found myself cruising up the Ohio River heading east from Cincinnati, and I came upon a little river town named Gallipolis, Ohio (population 3,641).

Towns like this with their orderly grid pattern of streets, and their quaint downtowns and storefronts, and their Victorian houses and tree lined streets just fascinate me. I zoomed in, switched over to street view, and started cruising along a road called 1st Avenue running parallel to the river. I turned left on a street called State Street, and there in the middle of the block, as I looked to the right, I saw an image of the past and an image of the future caught in a moment of time as they overlapped.

Cuba 55 Years On: Impact of Supply Chains

Moment to moment it’s all about creativity and courage. Over the longer term though, it’s about supply chains and sustainability.Cuba is a case in point; its history is so visibly shaped by the interaction of these short term and long term realities.

Arriving in Cuba for the first time is like stepping into a time capsule that has preserved different periods of the country’s history. There’s old Havana filled with cobblestone streets and Spanish colonial buildings. Then there are art deco houses and buildings from the 1930s, and brightly colored and polished American cars from the 1950s: Cadillacs; Ford Fairlanes; and Chevy Nomads. Then there are the little Russian Lada sedans, and the big soviet-style apartment blocks. And mixing in with all that, you can see new Hyundai cars, and recently restored Spanish colonial buildings and art deco houses being turned into art galleries and restaurants. There was then, and is now, a different supply chain connected to each of these periods that made them possible.

Supply Chain Simulation in 6 Easy Steps

Simulations are a great way to learn about and teach about how supply chains work. What used to be so complicated only a small group of experts could understand, is now accessible to  anyone wishing to use simulations to analyze supply chain operations and explore different possibilities – SCM Globe.

Taking Care of Business on the Silk Road

Simulations show the best way to support a continuous flow of merchandise on the ancient Silk Road was to have large stocks of inventory at key locations. They would act as buffers to absorb the fluctuations in product supply inevitably created by the bullwhip effect. Two such locations are shown in the screenshot below. [This article picks up where the second article “Taming the Bullwhip on the Silk Road” left off]

And this observation raises a big question: Who would have owned and operated the facilities where these huge inventory buffers were located? It required someone with a lot of money to store and protect the inventory, and It required someone who looked to the long term to make money, not just from one year to the next. Let’s see what emerges.

Taming the Bullwhip on the Silk Road

How was it possible in the year 210 A.D. to maintain a continuous flow of merchandise on the Silk Road and to match supply with demand as conditions changed from one year to the next? How could people without telephones or any form of communication faster than the pace of a camel caravan figure out how to operate this vast supply chain without continuously running out of products in one city and building up too much somewhere else? [This article picks up where the first article “Ancient Silk Road – First Global Supply Chain” left off]

Based on simulations of Silk Road operations, and a bit of historical research, an interesting answer emerges. This answer cannot be absolutely verified, yet it fits the available facts and provides a simple and coherent explanation. Let’s start with the simulation results. In the initial simulation the supply chain runs for eight weeks and then silk inventory runs out in Palmyra (4), as shown in the screenshot below.

Ancient Silk Road – First Global Supply Chain

Imagine it is the year 210 A.D. and you are the head of the largest merchant trading house on the Silk Road. The long prosperity of the Pax Romana has created strong demand in the Roman Empire for the luxury products that you import from China and India. Chief among those products is silk. Everybody who is anybody wants their clothes made of silk.

Along the four thousand miles of the Silk Road stretching from the borders of the Roman Empire in the west to the Middle Kingdom (China) in the east, there are many cities and many merchants, yet all know your company and your name — you are the Merchant House of Barmakid in the city of Merv.
