5. Production concept

Process stability/availability:______%

= total up-time in the body shop

Re-tooling or re-use factor:______%

= [1 – Project investment excluding operational costs / “all new“] x 100

with „all new“ = Value of the total installed investment

Degree of mechanisation:______%

= Automated Work Content* / Total Work Content*

* Work Content refers to the sum of Standardized Work Contents in the Body Shop, calculated according to the Harbour Report system, excluding lay-in operations, handling of parts, logistic operations

Bodyshop-Index BSI______[€ x hour/car unit /WSE]

* as calculated in section 5

No. of production sites:______
namely in: ______

______

Intended production volume:______units/year

Car body production lead time:______.__ minutes
= the time spent by the unit in the body shop, from the start of the first underbody parts to the handing over of the body-in-white to the paint shop, including
car body interim storage**

** More accurate definition (Harbour):

Start counting when work begins at the first station of the underbody (motor compartment or rear floor, whichever station begins first).
The end of the measurement is the beginning of the delivery from body in white to the paint shop. If the vehicle changes skids or pallets, the process ends as soon as the vehicle leaves the original pallet. If the vehicle is going on a lift to transfer to the paint shop, the process ends as soon as the body in white is in final position to begin transfer.

Cycle time (mainline bodyshop):______seconds

Degree of material utilisation: ______%

= 100% - scrap rate

(Sheet only, inhouse parts only, not including laser welded blanks)

Total number of parts in the BIW:______
