Methods and apparatus for scheduling delivery of an order via a wide area network. A computer system associates a customer point value with each customer according to a customer point system. The customer point values is determined with reference to customer order data. The computer system then divides the customers into customer groups, each of which has a range of customer point values. The system determines an actual capacity allocation distribution among the customer groups based on the customer order data. The system adjusts the range of customer point values for customer groups to cause the actual capacity allocation distribution to converge to a target capacity allocation distribution.
