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:______

< 100 g:______
100 g - 1 kg:______
1 kg - 5 kg:______
> 5 kg:______
(all assemblies broken down into their component parts)
