Abstract In this paper quantitative models are developed to assess errors probability and errors correction costs in internal logistics processes used to supply parts to assembly lines. Reference is made to continuous supply methods including line storage and just in time parts delivery. Event trees are adopted to keep track of unwanted events and error correction opportunities during the entire logistic process starting from material picking in the warehouse to containers delivery at the workstation and parts assembly. A numerical case study is included to show the method application and assess the contribution of each potential error to the overall quality cost in continuous parts supply systems.
