System and method for evaluating maintenance costs of products
First Claim
1. A method for use in a data processing system to learn behavior of maintenance costs of products and determine maintenance costs of products, using a learning database containing product characteristics, maintenance agreement conditions and actual historical maintenance costs associated therewith, comprising the steps of:
- receiving by the data processing system a selection of at least one product characteristic stored in said learning database;
determining by the data processing system, from said actual historical maintenance costs in the learning database, first maintenance cost estimations C0(i) associated with each modality i of said at least one product characteristic and building a first table storing the modalities and said first maintenance cost estimations associated therewith according to the equation

Abstract
A method and system to evaluate the maintenance costs of products, having learning and application phases. Each phase is divided into two steps. The first analyzes product characteristics. The second is based on maintenance agreement conditions. During the first step of the learning phase, a first maintenance cost is estimated over the domain of a first variable representing product characteristics. Correction coefficients, based on other product characteristics, may be estimated to improve the first maintenance cost estimation. During the second step new correction coefficients are estimated according to maintenance agreement conditions. During the application phase, a first maintenance cost estimation is done according to the modality of the first variable, and adjusted depending on other product characteristics and maintenance agreement conditions.
