Yield management method and system
First Claim
1. A yield management method for optimising a yield parameter resulting from assigning a capacity offered by a future instance of a service to each one of a plurality of different categories of requests competing for the capacity, the capacity being defined by at least one capacity variable, the method including the steps of:
- storing a set of historical profiles for each one of a plurality of previous instances of the service, the set including a historical profile of an historical value of each capacity variable reserved by each category, assigning a probability to each previous instance of the service, estimating a potential profile of a potential value of the capacity variable from each historical profile according to a corresponding current value of the capacity variable reserved by the category for the future instance of the service and according to a corresponding unconstrained demand of the capacity variable for the category in the previous instance of the service, defining a historical scenario for each previous instance of the service, the historical scenario including a final potential capacity variable from each corresponding potential profile, and determining an authorisation to allocate the offered capacity for each capacity variable of each category in the future instance of the service by applying a stochastic model to the historical scenarios according to the corresponding probabilities.

Abstract
A yield management method (300) and system, particularly for maximising a revenue that can be obtained from a given capacity that is offered by a cargo flight; the capacity is defined by two different variables consisting of the weight and the volume of the freights that may be transported by the flight. A set of historical profiles of the capacity (weight and volume) reserved by each category is stored (306) for different previous instances of the flight. Corresponding potential profiles are estimated (316-326, 332) independently for the weight and the volume. The estimation is carried out taking into consideration the corresponding capacity currently reserved by the category for a future instance of the flight; moreover, this result is emphasised according to a corresponding unconstrained demand for the category (not limited by the offered capacity). A series of historical scenarios of the demand at the departure of each previous instance of the flight are then obtained from the potential profiles (344). A stochastic model is applied (362-372) to the historical scenarios according to the corresponding probabilities for calculating the optimised weight and volume authorisations for each category.
