Abstract

A method of engineering a flexible process line which produces a first set of automotive vehicle assemblies and a materially different second set of automotive vehicle assemblies is provided, the method includes defining standardized task stations, determining at least first and second templates from a defined set of task stations for the first vehicle assemblies, combining templates to form a process line for the first set of vehicle assemblies, defining templates for the second set of vehicle assemblies, combining templates for the second set of automotive assemblies to form a process line for the second set of automotive assemblies, and determining a set of templates common to said first and second process lines and providing the common templates in combination with the templates which are discrete to the process line for at least one of the sets of automotive assemblies.

Claims

1. A method of engineering a flexible process line which produces a first set of different automotive vehicle assemblies and a second set of different automotive vehicle assemblies which are materially different from said first set of different assemblies, said method comprising:

defining a plurality of standardized task stations;

determining at least first and second templates drawn from a defined set of task stations for said first set of assemblies;

combining a plurality of templates comprising at least said first and second templates for said first set of assemblies to form a process line for said first set of assemblies;

defining at least first and second templates of a defined set of task stations for said second set of assemblies;

combining a plurality of templates comprising at least said first and second templates for said second set of assemblies to form a process line for said second set of assemblies;

determining a set of templates common to said process line for said first set of assemblies and said process line for said second set of assemblies and providing said common templates in combination with the templates which are discrete to said process line for at least one of said set of assemblies.

2. A method as described in claim 1 wherein at least one of said task stations presents said second assembly part on a workpiece presenter which has a tooling plate for a first assembly workpiece and a tooling plate for a second assembly workpiece.

3. A method as described in claim 1 wherein said first set of different automotive assemblies are automotive vehicle body weldment assemblies for passenger vehicles and said second set of different automotive vehicle weldment assemblies are for truck/sport utility vehicles.

4. A method as described in claim 1 wherein said first set of different automotive vehicle assemblies comprises front wheel drive assemblies and said second set of different automotive vehicle assemblies comprises rear wheel drive assemblies.

5. A method as described in claim 1 further including providing a combination of templates which are discrete for at least a second set of different assembly parts so that said process line can produce said first set of different automotive vehicle assemblies and said second set of different automotive vehicle assemblies concurrently.
