斯堪的纳尔公司致力于碳粉盒的再制造；由于生产过程中的高度不确定性，与普通制造相比，斯堪的纳尔公司和再制造行业一般都从事彩色碳粉盒和黑色碳粉盒的再制造，这些特点可能会限制应用精益生产原则的可能性。这些不确定因素主要是由两个因素造成的：返回芯的数量和质量。总体而言，这些特点使再制造物流更难控制。因此，本文的目的是分析精益生产的物流原则是否可以应用于再制造环境，特别是瑞典再制造企业斯堪的托纳AB。分析表明，精益生产原则可以应用于再制造环境，但有一定的约束条件。例如，对于案例公司，研究表明，根据精益生产原则，车间布局可以得到显着改善。从这一分析中可以得出的一个主要结论是，加工时间可变和回收材料的不确定性的固有特征对实施精益生产过程具有重大的负面影响。反之亦然，如果提供了准确的重组零件供应，精益生产物流的所有适当原则都可以在重组和测试阶段实施。
Scandi-Toner AB works with remanufacturing of toner cartridges; both color cartridges and black cartridges The company Scandi-Toner and the remanufacturing industry in general do, compared to ordinary manufacturing, have some specific characteristics that might limit the possibilities to apply lean production principles, due to the high degree of uncertainty in the production process. These uncertainties are mainly caused by two factors: the quantity and quality of returned cores. Overall, these characteristics make the remanufacturing material flow harder to control. Hence the purpose of this paper is to analyze if lean productions principles for material flow can be applied in a remanufacturing environment, and especially at the Swedish remanufacturer Scandi-Toner AB. The analysis shows that lean production principles can be applied in remanufacturing environments, with some constraints. For the case company the study showed that for example the workshop layout could be improved significantly according to lean production principles. The one major conclusion that can be drawn from this analysis are that the inherent characteristics of variable processing times and uncertainty in materials recovered have the major negative impact for implementing a lean production process. Vice versa, given an accurate supply of parts for reassembly, all the appropriate principles of a lean production material flow can be implemented in the phases of reassembly and testing.
