Problem solving (calculation)
Exercise 2
Determine the average demand per day, the buffer stock in tons, the Economic Order Quantity and the First reordering day (R_1) if the following data is given, and you can use the saw-tooth model! Show the inventory level over time (till the consumption of the first reordered stock starts to be consumed) in the empty diagram in the answer sheet! 
Initial quantity on stock: 1800 tons. 
Buffer stock should be enough for 8 days.
The lead time is 10 days.
The planning period is 100 days long, and the total demand during this period is 8000 tons.
The ordering cost is 100 euros per order. The cost of stock holding is 10 euros per one ton.
