PROBLEMS, POSSIBLE SOLUTIONS
What kind of decision you have to take in this
AND and
situation MORE PROBLEMS
how would you take this decision?
- You can not order more meat than you have space to store it
- Use historical data from your sales to determine how much you need to order
Replenishment lead time is very long:
How often to place an order for meat: once every two weeks, every week, every day?
- Follow-up the stock at the end of every day to check you need to order more/skip the order
- The more youDelivery costs vs.
keep in inventory, stocking
the longer costs
money is stuck in inventory. Money you don’t put in the inventory can be used for
investments orUncertainty
other financial benefits.
- SearchHow much
for a supplier meat
who to order?
can deliver faster than 4 weeks (can possibly be more expensive) = TRADE-OFF
Based on historical sales data and an analysis of customer behavior and consumption patterns
- Make the production lead time shorter (15 minutes): maybe you can already do some preparations to save some time like
(forecasting)
cutting the tomatoes, already unpack everything, pre-bake meat… (= WORK IN PROGRESS)
Watch out you don’t have to trow to much away! Do not prepare to much!
By the time the delivery arrives, the consumption pattern may have changed
- Use theRenegotiate or find
assembly-system from othereveryone
McDonalds: supplier
has awith
task toshorter replenishment
make the final order lead time
This will be more expensive.
- Use a registration system: order the food in advance
How much more are you willing to pay for a shorter lead time
- Make the waiting time more pleasant (maybe not in Corona-times)
Imagine you have a gamut of different kind of hamburgers
