Inflation 6.8% Year on Year…
CPI increased 6.8% in November, biggest jump in 40 years. I blogged back in July that I think 4%+ CPI increases may occur for quite a while without the FOMC raising core interest rates to try to cool it off. Combine the FOMC’s average-inflation targeting with new warnings that supply chain disruptions may last into […]
A Data Driven Success Story!
I recently received an encouraging message from Ryan, a data scientist and supply chain modeler at a $5B+ logistics company, that I’d like to share with his permission. Ryan reached out to the R for Data Science (R4DS) Supply Chain Slack channel, asking for recommendations on how to use R for recommending DC locations. After some […]
Supply Chain Design Using R: Unconstrained Warehouse/Customer Alignment
I had a great discussion recently on the R for Data Science (https://www.rfordatasci.com/ ) Slack channel about how to build a supply chain network model, aligning Customers to Distribution Centers (DC), using the R programming language. Because I am always eager to encourage people new to the supply chain design field, I wrote this small […]
Climate Change is an Existential Risk to Global Supply Chains
Supply chains are intricate, interconnected “systems of systems.” As someone who has dedicated their career to mathematically modeling the links and nodes in supply chains, I spend a decent amount of time thinking about how risk is correlated and magnified across these systems. As this article attests, COVID-19 put these supply chain risks front-and-center to the […]
Talking About Monte Carlo Simulation
I had a great time speaking about Monte Carlo Simulation at the Boston useR group on Monday. You can watch it here on YouTube. The Shiny app that I walk through in the talk is here: https://datadrivensupplychain.shinyapps.io/restaurant_sim_app/
The Fed’s “Beige Book” and Average-Inflation Targeting Impacts on Supply Chain
Eight times a year, the Federal Reserve puts out its Summary of Commentary on Current Economic Conditions (colloquially, its “Beige Book”), a perspective on the national economy gleaned from interviews with businesses across the country. As someone who is deeply interested in economics and econometrics, I find the Beige Book fascinating because it provides a […]
