Can someone please explain the plant scheduling codes? JohnZ are you listening? I would like a better understanding of how those worked, since my database is now showing some weird fluxuations. Thanks.

Have you seen this? I can't think of anything to add.

From http://www.camaros.org/numbers.shtml#CowlTag :

LOS - Fisher Body body scheduling code

The LOS (Los Angeles/Van Nuys) body scheduling code is a letter followed by one to three digits, e.g., F103. Based on data analysis only (there is no GM documentation yet available that describes this code) - but with consistent application to thousands of datapoints - CRG believes the code was used by LOS Fisher Body (and other plants that built multiple carlines) to aid in scheduling the body build order.

The letter indicates the approximate production day of the month for the start of the assembly of each vehicle body. It began with letter "A" on the first day of the month of the Fisher production calendar, incremented at the start of each additional production day to the next alphabetic letter, and was reset to letter "A" at the start of the next production month. (Note that the Fisher production calendar is known to differ slightly from the calendar month, and we also do not yet know exactly how the Fisher production calendar related to the Chevrolet monthly production reporting calendar.)

The one-to-three digit sequence number that follows the letter was reset to 1 at the start of each production day and was incremented serially with each body built by the factory as the day progressed. Data analysis indicates that the sequence number at the LOS plant was assigned regardless of model or body type. By this we mean that Camaros and full-size passenger cars both incremented the same sequence counter. The unit counter was reset to 1 the next day as the day-of-the-month code letter incremented to the next letter. In the example, F103 would indicate the sixth day of production for a given month and the 103rd body started on that sixth day of production.

Thanks alot Kurt, I knew I saw it somewhere. I even searched here at TC, and forgot to look over at CRG. Is it possible to have a plant scheduling code of 01C and the body have a plant code of a "S105", even some earlier than the actual 01C? I have many in my database that the plant codes don't jive with the build month/week.

I'd have to see the specific examples. Send Daniel or me an email.

The Fisher calendar was floating and not exact since it was just for internal purposes. Some months are consistent, some aren't. :)

Thanks for clearing that up Kurt, I guess that they only counted weekdays and not weekends and holidays, am I right?

My 02B H323 would be second week Thursday February 13 (1. February 1969 was a Saturday and the Wednesday 12th was a holiday)

And my 02C K351 would then by February 18 which was a Tuesday

How many cars were build every day?

You can guestimate the day, but it may be off a day or two. Sometimes the count included Saturdays.
About 250-280/day at LA.

I thought the K351 was the 351st car scheduled on the "K" day, how can that be if only 280 were build daily?

By this we mean that Camaros and full-size passenger cars both incremented the same sequence counter.

I take this to mean all body styles contributed to the count.:beers:

Yes, all the body styles contributed. About half were Camaro and half were full size cars.

I overlooked that info :clonk:

Thanks guys
