Abstract

An sourcing event management system includes a presentation layer, a business logic layer, an infrastructure layer and storage and operates to facilitate the creation of a bidding scenario, the opening of a bidding process, reception of bids from suppliers, the closing of the bidding process and the analysis of the bids received from the suppliers to determine an optimal bid award schedule. The sourcing event management system also includes a modified mathematical model that is solved, subject to constraints selected by a buyer and to variables specified by the buyer, to determine how the constraints can be modified to further optimize the bid award schedule.

Claims

1. A method for automatically generating at least one scenario used to optimize a bid:

award schedule, comprising;

a buyer specifying that a mathematical model includes at least one flexibility element;

a sourcing event management system using the results of a sourcing event to evaluate the mathematical model which results in an initial bid award value;

the buyer specifying a value for the mathematical model flexibility element;

the sourcing event management system using the specified flexibility element value to calculate a special mathematical model variable; and

the sourcing event management system evaluating the mathematical model subject to the special mathematical model variable to identify at least one scenario that will improve the initial bid award value.

2. The method of claim 1 further comprising the sourcing event management system displaying the at least one scenario that will improve the initial bid award value.

3. The method of claim 2 further comprising entering the at least one scenario into the sourcing event management system and the sourcing event management system evaluating a mathematical model subject to the entered at least one scenario to improve a bid award schedule.

4. The method of claim 1 wherein the resulting initial bid award value is determined by:

the buyer creating a bidding event scenario and causing the sourcing event management system to initiate the event;

the sourcing event management system receiving bids; and

the sourcing event management system evaluating the mathematical model subject to the accepted bids which results in an initial bid award value.

5. The method of claim 1 wherein the mathematical model is comprised of an objective function and one or more constraints.

6. The method of claim 5 wherein the objective function is comprised of at least one of a price term, a non-price term and a discounts term.

7. The method of claim 5 wherein the constraints are comprised of at least one buyer constraint and at least one supplier constraint.

8. The method of claim 7 wherein the at least one buyer and at least one supplier constraint are one of a published and an unpublished constraint.

9. The method of claim 1 wherein the flexibility element is a constraint flexibility variable.

10. The method of claim 1 wherein the constraint flexibility variable value is one of a relative value and an absolute value.

11. A method for automatically generating at least one alternative sourcing event scenario used to optimize a bid award schedule, comprising:

a buyer defining a plurality of constraints to an objective function, at least one of which is a flexible constraint, and storing the constraints in a sourcing event management system;

the buyer creating a first sourcing event and causing the sourcing event management system to initiate the event;

the sourcing event management system receiving and storing bids from one or more suppliers;

the sourcing event management system evaluating the objective function, subject to one or more of the plurality of the buyer defined constraints and the suppliers bids, resulting in an initial bid award value;

the buyer specifying a value for a constraint flexibility variable;

the sourcing event management system using the constraint flexibility variable value to calculate a special constraint variable for the at least one flexible constraint; and

the sourcing event management system evaluating the objective function subject to the special constraint variable to identify a scenario that will improve the initial bid award value.

12. The method of claim 11 further comprising the sourcing event management system displaying an indication of the identified scenario that will improve the initial bid award value.

13. The method of claim 12 further comprising entering the identified scenario into the sourcing event management system and the sourcing event management system evaluating the objective function subject to the entered identified scenario to improve a bid award schedule.

14. The method of claim 11 wherein the objective function is comprised of one of a price term, a non-price term and a discounts term.

15. The method of claim 14 wherein the identified scenario is comprised of one or more modifications to the plurality of buyer defined constraints.

16. The method of claim 11 wherein the plurality of buyer defined constraints are comprised of at least one published constraint and at least one unpublished constraint.

17. The method of claim 16 wherein the value of the constraint flexibility variable is one of a relative value and an absolute value.

18. The method of claim 11 wherein the special constraint variable is applied to one of a published and an unpublished constraint.

19. A computational device, comprising:

a memory, the memory including;

a sourcing event management system comprised of;

an optimization engine;

an objective function;

one or more constraints;

a bidding event scenario; and

bids received from one or more suppliers, the sourcing event management system evaluating the objective function, subject to the one or more constraints and received bids, which results in an initial bid award value, specifying a limiting value and a flexibility value for each of the one or more constraints;

using the specified limiting value and the flexibility value to calculate a special constraint variable for each of the one or more constraints; and

minimizing the objective function subject to each of the calculated constraint variable to identify modifications to the one or more constraints that will improve the initial bid award value.

20. The computational device of claim 19 further comprising the sourcing event management system displaying an indication of the identified modifications to the one or more constraints.

21. The computational device of claim 20 further comprising the sourcing event management system evaluating the objective function, subject to constraint modifications entered into the sourcing event management system, to improve a bid award schedule.

22. The apparatus of claim 19 wherein the objective function is comprised of one of a price term, a non-price term and a discounts term.

23. The apparatus of claim 19 wherein the constraints are comprised of at least one buyer constraint and at least one supplier constraint.

24. The apparatus of claim 19 wherein the at least one buyer constraint is one of a published constraint and an unpublished constraint.

25. The apparatus of claim 19 wherein the special constraint variable is applied to one of a published and an unpublished constraint.
