One of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics isâ€˜material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. In this paper the inter-plant traffic analysis issue on the basis of single channel queue model (M/M/1) is analyzed in a carmaker company (IKCO). Through the analysis, the production stop rate and relevant costs are estimated.
