Reduction of total production cost through the use of safety stock and process improvements
… on the shelves. Using research conducted at the Boeing 737 program as a case study, this thesis proposes the application of a multi-step approach to optimize the total cost of the production system, balancing holding cost (inventory) with the disruption cost of a shortage. The initial pilot shows …
