Abstract:

A method, system, and computer program product for determining availability and order scheduling of diverse products and services is provided. The method includes receiving an order with a plurality of element orders. The element orders are organized into one or more delivery groups. A first pass alignment date is determined for each element order, and the element orders are distributed to one or more scheduling applications in a first pass. The method also includes collecting a first pass response from the one or more scheduling applications, and the first pass response includes first pass element availability dates. The method further includes determining a second pass alignment date, including aligning the first pass element availability dates for the element orders in each delivery group, and communicating the second pass alignment date.
