Question $1.$ Consider a product with the following MPS record and an initial inventory

of $20$ units. Assuming that we are using the discrete logic that we use in class:

$($a$)$ Complete the Available and ATP rows of the MPS record.

$($b$)$ The following orders are received during Week $1($one by one, starting with the order in the first

row$)$:

Decide whether you will accept or reject these orders as you receive them. If you need

to reject an order on the date it is requested, state when it can be satisfied. Assuming

that the customer accepts your suggestion, revise the MPS record based on these new

orders. Orders are satisfied with a first$-$come, first$-$served rule, and partial delivery is not

accepted.
