manuel: look like portfolio - correlation?
dim: how to think about - track what demand looks like (fill inventory based on online demand - can be ); investments
pass gains to sales agent
sandra: two trips of sales agent (can't transfer inventory); giving more inventory -
when'd you want
⭐️sun~sat: replenishment is end of sat: tradeoff certainty vs
midway of time?
i like where your head is heading.
why should we do more thanmon, su
capex of runnig is 10million (15b $) - pay for smarter will payoff
delayed 2-phase distribution works (savings from printing, other savings from freeing printing capacity)
energy provider - (purchase; pay much more - hoarding)
buy my stuff and sell (option market - )
cheap and can return (broader assortment, )
steph: it knows me, so i'm confident that i'd like that
cristina: speed
## Aug 5
- amazon is compelling to buyers. assortment, data, subscription, delivery, review (prevent analysis paralysis using paradox of choice theory), building on modularized capability such as one click checkout
- selling book,
- chose bookstore with the vision of collecting data to learn how customers behave online
- ⭐️high conviction from day 1. founders are obsessed (elon, jeff) - long term plans (no detail is small)
- amazon is terrifying as it's conviction behind long term execution. evolution and development; they had luck that eventually made them successful,
- major supply chain decision variables
- location of warehouse, raw material suppliers, localization, promise time (standardize process), import location (port - eastern vs western; port of LA),
- number of vehicles, dispatching, routing, intelligence investment (prediction, prescription)
⭐️may be better to claasify before eliciting answer
distribution is last epoch, close to city as possible
centralized: less inventory, pool risk, economies of
decentralized: hub spoke (derek thinks solve key delivery time)
- experiment in tail for free
A100-B10-C1000
deliver faster to consumers as they have stores
amazon curate product, selection system, more
time, omni channel, curate products - walmart can figure out the right thing (cheap way of making)
segmentation
walmart has more money than time
small things aren't gonna move consumer behavior
🗣️skill: WOULD LIKE TO REMOVE TEMU - CONFOUNDER OF OUR DISCUSSION
last mile liquidity is expensive
do it faster and you have stores
that's why amazon bought wholefood (2017)
price, assortment, customer experience, speed
partnered with chile

## Discussion Questions for Class
### Question 1: Amazon's European Strategy
**Prompt:** Consider the following three options of designing Amazon's European distribution network:
a. Keep the status quo (three decentralized DCs serving each country independently)
b. Keep the existing DCs but centralize the management of them by possibly allowing a DC in one country to fulfill orders in another
c. Combine all DCs into a single DC serving multiple countries

- Inefficient capacity utilization
#### Option B: Centralized Management
**Pros:**
- Risk pooling benefits
- Better demand allocation
- Economies of scale in purchasing
- Flexibility in fulfillment
**Cons:**
- Increased complexity
- Cross-border shipping costs
