| Abstract: | This thesis is the closing element of my Bachelor Industrial Engineering and Management at the University of Twente in Enschede. It is performed at company X in the south of the Netherlands. The target is to describe, analyze and improve a specific part of the company X logistics system, i.e., airfreight of inbound logistics. Company X is a car manufacturer with its assembly plants all around the world. Car parts are produced in supplier plants all over the world and are shipped to these plants for final car assembly. This process is called “inbound logistics”. The critical element in Company X’s car manufacturing process is continuity. Assembly line stoppages are very expensive and must be avoided at all times. 2018 will be a critical year for Company X, as it must reach mass production volumes, fulfill the financial market expectations and stay ahead of competition. Therefore, all efforts are focused on timely delivery of parts to the assembly lines. Inbound logistics overseas can be done by boat, in containers or by plane, in ULDs. ULD is short for Unit Loading Devise. A ULD is an aluminum container used to store boxes/pallets during flight. These ULDs have an efficient fit in the aircraft and allow for easy handling. Obviously, container shipments are cheaper, but also slower, requiring longer term planning. For short term needs or unforeseen events, car parts are flown in, using boxes that are packed in ULDs. In order to minimize the high airfreight cost, this study focuses on improving the use of ULDs by designing a more efficient stacking pattern of standard boxes, the so-called IMCs. To improve the load efficiency of the ULDs a cargo layout model has been designed. This model calculates an efficient filling method on the basis of the size of ULD and IMCs used. This limits the cost per volume shipped. The model can be used by the handlers when loading the ULDs or by the freight forwarders in order to create pre-stacked pallets ready for ULD loading. The benefits of pre-stacking pallets for maximum ULD efficiency are less handling, more load stability and therefore less risk for transport damages and unforeseen delays. The benefit for the freight handlers is a higher ULD filling grade, thus decreasing freight cost per m3. In conclusion: using the Cargo Layout Model improves the reliability, predictability and efficiency of the inbound logistics process for Company X, decreasing the risk of faulty deliveries and ultimately line stoppages. It is recommended that the model is implemented as a base for the forwarders and freight handlers used by company X for its products. |
