Time Analysis in International Logistics Systems - With the 6Sigma Approach towards an International JIT-System

Time-based supply chain management is already realized to a certain extent – especially on a regional or national level. But in an international context the time focus is only visible in particular supply chain segments as for example the just-in-time delivery. Other areas of the global supply chain are only allowing a continuous parts flow with the help of stocks. For reducing these stock levels a consequent time measurement and structured 6sigma approach are implemented – particularly in the automotive sector due to the competitive cost pressure. Some chain elements like the customs process can only be leveled to a certain sigma degree and therefore bear some risk when calculating the supply lead time. Hence a stock free international supply chain is a vision but in practice a controlled stock level guarantees a smooth local production. The logistical chain is therefore consisting of a pull and push fragment with stocks to be pushed and the local parts supply to be pulled from the foreign plant via a JIT system.
