Amazon Air’s Supply Chain Obsession

MARCH 24, 2022

There is nothing like a pandemic and a European war to highlight the value of logistics, writes The Wall Street Journal (March 17, 2022).  Amazon’s growing fleet of planes shows that it is investing hard to deliver—probably at the expense of FedEx, UPS, and DHL.

Amazon’s cargo airline currently makes an average of 187 flights a day, compared with 85 in May 2020.

Since the Covid-19 crisis started, e-commerce purchases have skyrocketed and a lot of belly-hold space in planes has been removed. Many airfreight companies have seized the opportunity to grow. Amazon has taken the lead. It now has as many as 110 jets—less than DHL’s 202, UPS’ 289 and FedEx’s 474 but a lot more than the 50 it had at the start of 2020.

Wal-Mart Ramps Up Global E-Commerce

FEBRUARY 23, 2014

Wal-Mart says it has cracked the code for speedy, same-day grocery delivery—in Mexico. As retailers like Wal-Mart and rush to expand home delivery in the U.S. to groceries, the retail giant is looking across the border for help: Its high-end Mexican grocery chain, Superama, already delivers groceries in as little as 3 hours.

Wal-Mart has ramped up its global e-commerce operations over the past few years, writes The Wall Street Journal (Feb. 19, 2014), in hopes of catching up to online rival The company vowed to match Amazon’s service offerings within 2 years. Currently, only about 2% of Wal-Mart’s sales come from the Web.

The company has been testing home-grocery delivery in Colorado and California, but it hasn’t announced a timeline for taking the service nationwide. It is also experimenting with grocery delivery in such cities as Buenos Aires and Santiago, Chile. Wal-Mart says it is “committed to being the online global leader in grocery delivery.”

Mexico provides $27 billion in sales and contributes 6% of the company’s global sales. Superama helped Wal-Mart achieve a 92% market share in the home delivery of groceries in Mexico. A fifth of its grocery orders arrive via mobile-phone apps, computers and tablets. The service is strongest in Mexico City, where much of Mexico’s wealth is concentrated. The capital’s snarled traffic and cramped grocery stores make delivery from Superama appealing for the well-to-do.

The majority of the grocery deliveries in Mexico come from supermarkets that are open to the public. But in the future, Wal-Mart de México plans to deploy more “dark stores”— spaces used exclusively to fulfill online orders. Such “closed” stores are more efficient: Wal-Mart’s inaugural dark store in Mexico City handles the same volume of orders as 5 stores open to the public.

America’s Second Railroad Revolution

FEBRUARY 4, 2014

Union Pacific's Bailey Yard

Rail is on a roll in the U.S. As Forbes(Feb.10, 2014) writes, The relic of the 19th century will become the most important logistics system of the 21st century.” Thanks to leaps in technology, more and more freight traffic has moved from roads to rails, where trains can move one ton of goods about 500 miles on a single gallon of fuel. The industry, so recently an aging also-ran in the age of superhighways, has seen revenues surge 19% to $80.6 billion since 2009, creating 10,000 new jobs at railroad companies. Less than a decade ago diesel prices were so low that manufacturers rarely considered rail for shipments of less than 1,000 miles. Now they’re ditching trucks in favor of trains for jobs as short as 500 miles.

All of which is driving a multibillion-dollar revival in rail R&D and infrastructure, investment unseen in America since the transcontinental railroad. Thousands of new state-of-the-art locomotives–far more fuel-efficient and less polluting than the ones they replace–are now operating on U.S. railroads. And the boom (with $20 billion in infrastructure spending annually) has been underwritten by industry, with no cost to taxpayers. Further, the Rail Safety Improvement Act of 2008 required railroads to fund, build and implement a new, safer “Positive Train Control” system by the end of 2015, refitting locomotives and tracks, and placing GPS devices on every locomotive.

This technology has been revolutionizing freight hauling, allowing the railroads to pinpoint a locomotive’s location within one yard. And instead of sending trains speeding across the country only to stop at each red signal, the new system means conductors will be able to know about planned stops well in advance, allowing them to simply reduce speed (and fuel consumption) to a level that won’t force them to stop altogether and burn major amounts of fuel when restarting from a standstill.
