Abstract

An integrated production management system is disclosed for closed loop management of production requests within an enterprise. The production management system includes a business management (enterprise resource planning) system that issues production requests based upon business requirements. A production management system executes supervisory process control and manufacturing information applications providing high level control of production equipment and processes. A workflow engine, interposed between the business management system and production management system, executes event-driven logic to carry out negotiated production requests through communications with the production management system. The negotiated production requests arise from closed loop negotiations carried out between the workflow engine and business management system.

Claims

1. An integrated production management system comprising:

a business management system for providing a production request;

a production management system executing supervisory process control and manufacturing information applications providing high level control of production equipment and processes; and

a workflow engine, interposed between and communicatively coupled to the business management system and production management system, the workflow engine executing event-driven logic to carry out a negotiated production request, based upon the production request received from the business management system, through communications with the production management system, wherein the negotiated production request arises from closed loop negotiations carried out between the workflow engine and the business management system.

2. The integrated production management system of claim 1 wherein the business management system comprises an enterprise resource planning application.

3. The integrated production management system of claim 1 wherein the production management system comprises a supervisory process control and manufacturing information application.

4. The integrated production management system of claim 1 wherein the workflow engine resides on a network node separate from a network node including the business management system.

5. The integrated production management system of claim 1 wherein the closed loop negotiations are automated.

6. The integrated production management system of claim 1 wherein messages between the business management system and the workflow engine during closed loop negotiations are formatted according to an industry standard.

7. The integrated production management system of claim 6 wherein the industry standard is based upon an ISA standard.

8. The integrated production management system of claim 1 wherein messages between the business management system and the workflow engine during closed loop negotiations are formatted according to a schema.

9. The integrated production management system of claim 1 wherein the production request specifies a quantity.

10. The integrated production management system of claim 9 wherein the production request specifies a time.

11. The integrated production management system of claim 9 wherein the production request includes a quality specification.

12. A workflow engine for integrating management of production requests issued by business management systems and fulfilled by production management systems, the workflow engine including:

a business management system interface for receiving a production request from a business management system;

a production management system interface for communicating with a production management system; and

event-driven workflow logic to carry out a negotiated production request based upon the production request received from a business management system, through communications with the production management system, wherein the negotiated production request arises from closed loop negotiations carried out between the workflow engine and the business management system.

13. The workflow engine of claim 12 wherein the workflow engine resides on a network node separate from a network node including the business management system.

14. The workflow engine of claim 12 wherein messages between the business management system and the workflow engine during closed loop negotiations are formatted according to an industry standard.

15. The workflow engine of claim 12 wherein messages between the business management system and the workflow engine during closed loop negotiations are formatted according to a schema.

16. A method for coordinating operations, via networked communications, of a business management system and a production management system via an interposed event-driven workflow engine including logic for carrying out production requests received from the business management system through communications with the production management system, the method comprising:

receiving, by the workflow engine, a production request issued by a business management system;

generating a negotiated production request based upon the production request by the business management system, wherein the negotiated production request arises from closed loop negotiations carried out between the workflow engine and the business management system; and

communicating, by the workflow engine, with a production management system in accordance with event-driven workflow logic, to carry out the negotiated production request using production resources controlled by the production management system.

17. The method of claim 16 wherein the generating step comprises generating a production schedule based upon available production resources.

18. The method of claim 16 wherein the generating step comprises transmitting, by the workflow engine, a negative response to the production request based upon production resource availability.

19. The method of claim 16 further comprising the step of re-negotiating the negotiated production request in response to a changed condition.

20. The method of claim 19 wherein the changed condition involves a market condition.

21. The method of claim 19 wherein the changed condition involves a production condition.

22. A computer-readable medium including computer-executable instructions for coordinating operations, via networked communications, of a business management system and a production management system via an interposed event-driven workflow engine including logic for carrying out production requests received from the business management system through communications with the production management system, the computer-executable instructions facilitating performing the steps of:

receiving, by the workflow engine, a production request issued by a business management system;

generating a negotiated production request based upon the production request by the business management system, wherein the negotiated production request arises from closed loop negotiations carried out between the workflow engine and the business management system; and

communicating, by the workflow engine, with a production management system in accordance with event-driven workflow logic, to carry out the negotiated production request using production resources controlled by the production management system.
