Abstract

An improvement in decision automation employing a ZDD rule model indicative of a business or engineering rule to provide decision support to a user. The computer-implemented improvement automatically identifies compliant inputs for the rule processing system according to at least one input initially supplied by a user, and is particularly useful for determining product configuration, engineering designs, various outcome of planning scenarios, etc. Once a user selects an initial value(s), remaining compliant values unique to the user-selected value(s) are automatically identified. The improvement reduces time required to manually select inputs. In one embodiment, the improvement includes an I/O interface to enable the user to choose and observe inputs, an autoselect ZDD constructed from compliant inputs of the rule model, and a ZDD processing module that processes said autoselect ZDD in order to provide for the user a set compliant inputs for the ZDD rule model according to the user input. The automatic input selection routine may be executed at decision automation runtime, or executed and stored a priori for subsequent processing during runtime.

Claims

an autoselect system implemented with said rule processing system to identify a set of compliant inputs of said rule based on at least one user input selected by said user, said autoselect system including a user interface to enable the user to select said at least one user input and a processor to automatically generate and indicate to said user other compliant inputs of said set based on said at least one user input.

2. The improvement of claim 1, wherein said inputs comprises enumerations of attributes of a business or engineering rule.

3. The improvement of claim 2, wherein said autoselect system builds an autoselect ZDD based on compliant inputs of said rule and processes the autoselect ZDD to produce set of compliant selections for said inputs.

4. The improvement of claim 3, wherein said autoselect system separately builds an autoselect Include ZDD and an autoselect Exclude ZDD to represent said autoselect ZDD.

5. The improvement of claim 4, wherein said autoselect system reorders nodes of said autoselect Include ZDD and autoselect Exclude ZDD to reduce the complexity thereof.

6. The improvement of claim 5, wherein nodes of said ZDDs have respective index numbers associated with said attributes and enumerations thereof and said autoselect system aligns the indices of respective nodes of said autoselect Include and autoselect Exclude ZDDs to facilitate processing.

7. The improvement of claim 6, wherein said autoselect system builds and stores the autoselect ZDD during rule packaging whereby to reduce processing time during execution of said rule processing system.

8. The improvement of claim 6, wherein said autoselect system builds the autoselect ZDD on-the-fly during runtime of said computer-implemented rule processing system.

9. In a computer-implemented rule processing system utilizing a ZDD rule model that responds to selection of enumerations of attributes in order to provide selection advice to a user for achieving compliancy of said rule model, an improvement comprising:

an autoselect system implemented with said rule processing system to provide additional compliant selections based on at least one initial input enumeration of said user, said autoselect system including a user interface to enable the user to select said initial input enumeration;

an autoselect ZDD constructed from compliant enumerations of said rule model; and

a processing module responsive to said initial input enumeration of said user to automatically provide said additional compliant selections of enumerations.

10. The improvement of claim 9, wherein said processing module divides said autoselect ZDD into an autoselect Include ZDD and an autoselect Exclude ZDD prior to automatically providing said user with additional compliant selections.

11. In combination with a rule processing system employing a ZDD rule model indicative of a business or engineering rule to provide decision support to a user, a computer-implemented system to automatically identify compliant inputs for the rule processing system according to at least one user input, said computer-implemented system comprising:

an I/O interface to enable the user to choose and observe inputs,

an autoselect ZDD constructed from compliant inputs of said rule model, and

a ZDD processing module that processes said autoselect ZDD in order to provide for the user a set compliant inputs for said ZDD rule model according to said at least one user input.

12. The computer-implemented system of claim 11, wherein said processing module enables the user to change an initial user input and, in response thereto, provides alternative compliant inputs based on a change in said initial user input.

13. A computer-implemented rule processing system to determine satisfiability of a business or engineering rule represented by a zero-suppressed binary decision diagram (ZDD) rule model, said system comprising:

an execution module to indicate compliancy of said rule according to selection of attributes and enumerations values for said attributes,

an autoselect module that provides automatic selection of enumeration values based on selection of an initial value for at least one enumeration,

a user interface to enable a user to select a value for at least one enumeration, and

14. The computer-implement system of claim 13, wherein said processing module iteratively enables said user to select an alternative enumeration value whereby, in response, said processing module determines and identifies other compliant enumeration values based on said alternative enumeration value selected by said user.

15. In a computer-implemented rule processing method to determine satisfiability of a ZDD representation of a business or engineering rule, a method of providing a set of compliant enumeration values for respective attributes of said rule comprising:

obtaining a user selection of at least one enumeration value of an attribute,

determining a set of compliant enumeration values of other attributes according to said user selection,
