Bruce Nelson sent me an article that both he and I find humorous. It's humorous because we have written frequently about part's stock-outs and how to use the Theory of Constraints (TOC) replenishment model to overcome a shortage of parts while reducing the inventory by 40-50%. I guess I expected more from Boeing as parts of this company have been using TOC for years.
Part's shortages many times come from the classic Min/Max replenishment system, so I suspect this is potentially the cause of Boeing's seat shortages on it's Dreamliner aircraft which has been plagued by problems throughout its short history. Any way, here is a link to this article.
