Effektivisering av materialhantering vid montering av gruvpumpar : Med en optimerad layout

Sammanfattning: Purpose and question formulations: The purpose of the thesis is to analyze the material flow during assembly of mine pumps and identify the wastes that occur in it. What will also be presented is a more optimal layout that will reduce the waste that exists today and create a more efficient material flow. Based on the purpose of the study, three question formulations were created and answered:   (1)   What wastes occur in internal material handling during assembly?   (2)   How can material handling be improved during assembly?   (3)   How can the layout be optimized?   Method and implementation: A case study has been conducted on a global company in the mining industry that manufactures customer-specific pumps. Data was collected through time studies, observations, semi- and unstructured interviews and through the internal system. A literature study was conducted to be able to link the theory with the empiricism. The theory was obtained from books and scientific articles.   Results: After analysis of the material flow at the fall company, several wastes were identified in the form of waiting, warehouses, unnecessary transport, unused expertise and defective products. There is no clear communication system between planning, warehousing, quality department and assembly which is a reason for the wastes created. Another reason is that there is no connection between the different stations of assembly which creates an inefficient flow of material due to the current layout.   Conclusions: The conclusions that can be drawn from this study are that a non-optimal layout combined with a missing system between the relevant departments for assembly creates an inefficient flow of material. Some lean tools, the 10 principles for efficient material handling and the guidelines for developing an optimal layout create a more efficient material flow.
