There can be found a lot of sources in the literature which dedicate wide space to description of waste created in manufacturing processes. On the other hand there is very little literature dealing with specific logistic wastes. Everybody knows the saying: “You can’t make something out of nothing.” …of course, resources are the key ingredient to create anything – but the key issue is connected with the usage of such ingredients, usually unproductively or using the wrong ones, towards wrong output. In all the cases, waste is present – costs created, man capacity burned, alternative opportunities for value add/creation are lost and customers left unsatisfied. Seeing the scope of logistics, it might be understandable why the wastes in logistics are not that visible as in other functional company areas. Here are the main logistics sources of waste (Goldsby & Martinchenko 2005: 14): Inventory, Transportation, Space&facilities, Time, Packaging, Administration, Knowledge One of the most important decisions regarding waste elimination in running production, as well as in newly planned production, is the part presentation of materials/parts on the line. Part presentation means the way how to supply materials from storage/supplier to the operators on the line. The performance of the production/assembly line as well as other performed activities will be affected by this decision. It is crucial to deal with timing of such decision – what will be part of the objective of this research. This research will analyze deep in detail several modes how to present parts to the production line. Here are some of them: 1. Traditional part presentation with its use of standard containers is the most used one, nevertheless not the leanest one. It causes high WIP size on the line as well as high usage of space. 2. Kitting stands for the system of feeding components and subassemblies on the production line. By proper application, a benefit of space and WIP size can be obtained, on the other hand a disadvantage of additional handling can be observed. 3. Tote boxes & Gravity Flow Racks. Tote box (called also Tote) stands for a small plastic box with a limited amount of parts wrapped already at supplier side. Gravity Flow rack stand for a specific purpose constructed rack at place of use. Flow rack is fed with tote boxes to present the parts to the operator at the cell in the arm’s reach. The benefit of this model is the elimination of additional handling and the presentation of parts at arm’s reach – on the other hand this system is selective seeing the dimension limitations of totes vs. parts, as well as the weight of a tote.
