Automated determination of applicability and value of discounts for a purchase order

摘要

A method for automatically determining applicability and value of any discounts for a purchase order from a client computer, the determinations being made by the client computer itself. In some embodiments, the client computer receives (from a server to which the order is being placed) coupon programming, determines applicability and value of discounts using the coupon programming, and sends discount information for an order to the server. The coupon programming may comprise a rule engine, implemented by rule programming, having one or more sets of rules and a processing relationship between the sets of rules and the rules in each set of rules. The rule engine may comprise a recursive rule program. In some embodiments, the applicability and value of any discounts for an order is determined by a server that receives the order, the determinations being made by using a rule engine implemented by rule programming.

主权项

1. A computer-implemented method comprising:
sending a recursive engine to a client device, wherein the recursive rules engine comprises a set of discount rules configured automatically determining a purchase order discount from a coupon code when a purchase order is made and when a purchase order is modified, and wherein execution of the recursive rules engine comprises:
recursively evaluating a first set of rules for determining an applicability of the purchase order discount;recursively evaluating a second set of rules for determining a discount value relating to an applicable discount;recursively evaluating the first set of rules and the second set of rules by performing an automatic process that recursively calls itself; receiving a purchase order placed by a user of the client device along with a coupon code; receiving the purchase order discount from the client device for the purchase order as automatically determined by the inks engine upon placement of a purchase order; relying on the determination of the rules engine; applying the discount without independently determining the purchase order discount; and processing the purchase order along with the purchase order discount.
