Abstract

A method and system for specification and execution of complex pricing calculations for the insurance industry using a declarative approach to specify and execute the rules. Pricing Illustrator/Configuration is a unique combination of a process and system that defines, tests and implements complex business computations such as premium computations for the insurance sector. The invention provides a repeatable and well-defined process for specification, design and implementation of the rules and a flexible, rule based calculation/pricing engine that implements the rules defined without any programming. Using the concept of declarative rules, Microsoft Excel as the design time tool to specify the rules and execute the spreadsheet at runtime to compute the premium, the invention defines, tests and refines the rules in relation to a business need.

Claims

1. A system for making calculations, said system comprising:

A business specification that provides commands in accordance with selected definitions, assumptions and business rules;

A family of blueprints for implementing calculations, each blueprint of said blueprint family including rating documents that precisely specify formulas, and a rate loader document that specifies how rates and factors are to be loaded during the calculations, said blueprint being responsive to business specification commands to provide a blueprint signal; and

A core engine that is responsive to blueprint signals and that is also responsive to operator command signals and to acquired data to provide a calculation output signal.

2. The system of claim 1 where said core engine selects a blueprint from the family of blueprints, said core engine selecting the blueprint in accordance with the calculation input command.

3. The system of claim 2 wherein said core engine determines the input data that is required to make the commanded calculation in accordance with the selected blueprint.

4. The system of claim 3 wherein said core engine loads selected data in response to the blueprint.

5. The system of claim 4 wherein said blueprint further includes a user interface, said blueprint being further responsive to form specification commands that define the user interface.

6. The system of claim 4 wherein said system includes a rate loader that is responsive to command signals from rates and loader specifications of the blueprint.

7. The system of claim 6 further comprising a presentation layer for presenting user interface forms.

8. The system of claim 7 wherein said presentation layer receives and verifies input data.

9. The system of claim 8 wherein said rate loader is responsive to the rate loader specification of said blueprint to acquire rates and factor data and supply such rates and factor data to the core engine.

10. A process of performing calculations in a core engine, said process comprising the steps of:

Developing business specifications that define the terms, assumption and rules that express the steps for making a calculation;

Creating a family of blueprints, each of said blueprints corresponding to a selected one of the developed business specifications, each of said blueprints respectively including rating sheets that define the calculations as formulas and also respectively including a rate loader specification that specifies how rates and factors are acquired during the calculations in the core engine;

Providing an initiation signal to the core engine to cause the core engine to begin calculations;

Inputting the data from a selected blueprint into the core engine to determine the particular rating sheet and rate factors corresponding to the selected blueprint;

Acquiring data in the rate loader in accordance with the blueprint instructions;

Performing the computations in the core engine in response to data acquired by the rate loader; and

Providing an output command in accordance with the completed computations.

11. The process of claim 10 wherein said business specifications are developed from product definitions and modification to business rules.

12. The process of claim 11 wherein said step of creating a blueprint further includes developing a user interface.

13. The process of claim 12 wherein the user interface is developed by selecting a field having a predetermined set of properties.

14. The process of claim 11 wherein the rate loader reads the rate loader specification of the blueprint and provides appropriate data to the core engine in response to commands and intermediate calculations from the core engine.

15. The process of claim 14 wherein the step of creating the blueprints includes rating sheets that are organized into a first subpart, said first subpart defining all of the inputs that are needed to perform the calculation for all applications.

16. The process of claim 15 wherein said step of creating the blueprint includes rating sheets that include a second subpart, said second subpart defining all of the rates and factors that are required to perform the computation in all applications.

17. The process of claim 16 wherein said step of creating the blueprints includes rating sheets that include a third subpart, said third subpart separating the calculator into a number of parts, each of said parts corresponding to a logical part of the computation.

18. The process of claim 17 wherein said step of creating the blueprints includes rating sheets that include a fourth subpart, said fourth subpart defining all of the outputs that are applicable to a given calculation, including all intermediate values and the final results of the calculation.
