Let us consider again the problem described in Using Strong Propagation on Reservoirs: the Balance Constraint. This time, rather than handling all calls by a single person, there are several operators dealing with customer requests.

When a new request is received, the customer is dispatched to an available operator. The operator engages in the same procedure as in the previous example, either proposing a delivery date or declining to deliver the product by the next month. If the customer accepts the proposed date, it becomes a due date on which the enterprise commits to deliver the ordered product.
