Abstract

A mechanical procedure is performed using a sequence of instructions generated from a relational data base. The data base includes at least one unit operation file containing data associated with the performance of a single unit operation, indications of prior operations that must be performed, and any support files that are required by each unit operation file. There is a generic instruction file containing a plurality of generic instructions. A sequence of unit operations to perform the mechanical procedure is first defined, using the information in the unit operation files. After this arranging of the unit operations, a series of task-specific instructions is generated for each of the unit operations by selecting and completing a series of generic instructions using information in each pertinent unit operation file.

Claims

1. A method for performing a mechanical procedure, comprising the steps of:

providing a computer system that includes a relational data base, the data base comprising

at least one unit operation file containing data associated with the performance of a single unit operation including data identifying one or more specific parts and references to generic instructions and a pointer to any prior unit operation and an indication of any subsequent unit operation that must be completed to perform the mechanical procedure, and

a generic instruction file containing a plurality of generic instructions;

arranging a sequence of unit operations that must be performed to complete the mechanical procedure based upon the pointers provided by the at least one unit operation file as to any prior unit operations and any subsequent unit operations; and

generating a series of instructions for performing the mechanical procedure in the sequence of unit operations established by said arranging step, the step of generating including a step of creating a series of task-specific instructions for each of the unit operations by integrating the data provided by each unit operation file including the data relating to one or more specific parts with generic instructions from the generic instruction file.

2. The method of claim 1, wherein the step of providing a computer system including a relational data base includes the step of providing a computer system that includes at least one support file containing data referenced by the at least one unit operation file, and wherein the step of creating a series of task-specific instructions includes the step of integrating data from the at least one support file to complete the generic instruction.

3. The method of claim 1, wherein the step of providing a computer system that includes a relational data base includes the step of providing a computer system that includes a generic instruction file containing at least one generic instruction selected from the group consisting of a caution instruction, a warning instruction, an obtain special tool instruction, a remove instruction, an install instruction, a clean instruction, a reuse instruction, a discard instruction, and an inspect instruction.

4. The method of claim 1, wherein the step of providing a computer system that includes a relational data base includes the step of providing a computer system that includes a representation of a visual image of an article in the unit operation file that is to be displayed during the unit operation.

5. The method of claim 1, wherein the step of providing a computer system that includes a relational data base includes the step of providing a computer system that includes a unit operation file that has at least one data element selected from the group consisting of identifications of at least two parts, a sequence number for each part, and a generic instruction code reference for each part.

6. The method of claim 1, wherein the step of generating a series of instructions includes the step of

generating at least one instruction requiring a response by an entity performing the mechanical procedure.

7. The method of claim 1, including the additional step, after the step of generating, of performing the series of instructions produced in the step of generating.

8. The method of claim 7, wherein the step of generating a series of instructions includes the steps of generating at least one instruction requiring a response by an entity performing the mechanical procedure;

and halting generation of additional instructions until a response is received.

9. The method of claim 7, including the additional step, after the step of performing the series of instructions, of automatically preparing a record of the procedure performed by the entity.

10. The method of claim 2 wherein the step of providing a computer system that includes at least one support file includes the step of providing at least one support file which includes a consumables listing.

11. The method of claim 2 wherein the step of providing a computer system that includes at least one support file includes the step of providing at least one support file which includes a parts required listing.

12. The method of claim 2 wherein the step of providing a computer system that includes at lest one support file includes the step of providing at least one support file which includes a special tools listing.

13. The method of claim 2 wherein the step of providing a computer system that includes at least one support file includes the step of providing at least one support file which includes a records output listing.

14. A method for performing a mechanical procedure comprised of at least one unit operation, the method comprising the steps of:

providing a plurality of generic instructions;

providing a computer system that includes a data base comprising a unit operation file containing data associated with the performance of a single unit operation including data identifying one or more specific parts and references to the generic instructions; and

automatically generating a series of task-specific instructions for performing the unit operation by selecting and completing a series of generic instructions based upon the data provided by the data base including data identifying one or more specific parts.

15. Apparatus for providing instructions during the performance of a mechanical procedure, comprising:

a display screen;

a memory containing a relational data base, the data base comprising

at least one unit operation file containing data associated with the performance of a single unit operation including data identifying one or more specific parts and references to generic instructions and a pointer to any prior unit operation that must be completed to perform the mechanical procedure, and

a generic instruction file containing a plurality of generic instructions;

means for arranging a sequence of unit operations that must be performed to complete the mechanical procedure based upon the pointers provided by the at least one unit operation file as to any prior unit operations that must be completed to perform the mechanical procedure;

means, responsive to said arranging means, for generating a series of instructions for performing the mechanical procedure in the sequence of unit operations established by said arranging means, the means for generating including means for creating a series of task-specific instructions for each of the unit operations by integrating the data provided by each unit operation file including the data relating to one or more specific parts with generic instructions from the generic instruction file; and

means for sequentially displaying the series of task-specific instructions on the display screen.
