Abstract

A method for controlling a process of realizing a product. The method defines activities of the process, their precedence relationships and the flow of information among the interconnected activities required to create the product. Resources are allocated and the defined activities are scheduled to complete the process. The method monitors the allocated resources and outputs of the interconnected activities and controls the process by dynamically reconfiguring the activities in accordance with time-variant criterion and selectively modifying the activities in accordance with monitored outputs of the activities to maintain optimal design, fabrication and assembly of the product.

Claims

1. A method for managing a process of realizing a product comprising the steps of

defining activities and information flow among interconnected ones of the activities, and

controlling the process by monitoring each of the defined activities and deriving solutions in response to operation of the activities for dynamically reconfiguring the activities in accordance with user entered and time-varient criteria by selectively modifying the monitored activities to maintain continuous optimal design and manufacture of the product.

2. A method for managing a process of realizing a product comprising the steps of

defining the activities and information flow among interconnected ones of the activities,

allocating resources to and scheduling the defined activities,

monitoring the allocated resources and outputs of each of the interconnected activities, and

controlling the process by deriving solutions in response to operation of the monitored activities and dynamically reconfiguring the activities in accordance with the derived solutions and with both user entered and time-variant criteria by selectively modifying the activities in accordance with the monitored activity outputs to maintain continuous optimal design and manufacture of the product.

3. The product realization method set forth in claim 2 wherein said defining step comprises the steps of

generating data flows defining functions comprising each activity, and

simulating operation of the generated data flows.

4. The product realization method set forth in claim 3 wherein said resource allocating and activity scheduling step comprises the steps of

determining status of each activity, and

estimating time required to perform each activity.

5. The product realization method set forth in claim 4 wherein said resource and output monitoring step comprises the step of

receiving status of each activity and of the allocation of the resources.

6. The product realization method set forth in claim 5 wherein said controlling and modifying step comprises the steps of

deriving solutions in response to operation of the activities for enabling reconfiguration of the process and assigning classification codes to each derived solution identifying resulting design and manufacture changes of the product,

selecting ones of the derived solutions in accordance with the assigned classification codes, and

modifying ones of the activities in accordance with the selected solution to maintain optimal design and manufacture of the product.

7. The product realization method set forth in claim 6 wherein said solution deriving step comprises the steps of

detecting messages generated by each activity,

generating causes of an activity failure upon detecting one of said messages identifying a failure occurring in an activity,

identifying ones of the activities that may be sources of the one activity failure,

listing ones of the activities that may be affected by said identified source activities, and

checking for other ones of the activities that may be sources of said one activity failure.

8. The product realization method set forth in claim 7 wherein said solution selecting step comprises the steps of

evaluating solutions for correcting said activities identified as possible sources of said one activity failure,

classifying each of said evaluated solutions,

choosing one of said evaluated solutions, and

appraising classification of said chosen solution.

9. The product realization method set forth in claim 8 wherein said activity modifying step comprises the steps of

accepting said chosen solution, and

reconfiguring said activities in accordance with said accepted solution.

10. The product realization method set forth in claim 8 comprising the step of

enabling a user terminal access to said product managing method.

11. The product realization method set forth in claim 10 wherein said solution selecting step comprises the step of

changing criteria defining said classification codes at various user defined times.

12. A method for managing a process of realizing a product comprising the steps of:

generating directed data flows defining activities interconnected in a precedence relationship to form the product realization process,

simulating operation of the generated activity directed data flows,

allocating resources to and scheduling the defined activities of each activity,

determining status of each activity,

estimating time required to perform each activity,

receiving status of an initiation and completion of activities and of the allocation of the resources,

deriving solutions in response to operation of the activities for enabling reconfiguration of the product realization process and assigning classification codes to each derived solution identifying resulting design and manufacture changes of the product,

selecting ones of the derived solutions in accordance with the assigned classification codes, and

modifying ones of the activities in accordance with the selected solutions to maintain optimal design and manufacture of the product.
