Tiivistelmä
The objective of the thesis was to clarify the possibilities of improving the productivity of pre- assembly by using an external service provider to deliver complete assemblies to the assigner company. The study was performed for the assembly of driveline units that were assembled in- house. The research included identification of the reserved resources that were compared with the cost estimates quoted from the supplier candidates.
The research methods used in this study were quantitative and qualitative. The assembly resource data was collected quantitatively from the ERP and PDM systems of the assigner company. Qualitative methods involved observations conducted at the pre-assembly place and the warehouse facilities. The key persons of different departments were interviewed. A request for quotation regarding the assembly process costs was sent to four supplier candidates.
The results showed that the outsourcing of the driveline assembly is not reasonable. The materials management is very complex due to the large number of different assembly unit variants. The current operations model requires high flexibility, since the product specifications are changed at short notice. In addition, the materials management system and the current material structure model do not support the outsourcing. The quotations received from supplier candidates showed that there was no partner available that could perform the assembly process with higher efficiency.
The study was assigned by a Finnish manufacturing company. Organizations looking for possibilities to improve their productivity will benefit from the results of the study. The thesis is relevant for different organizations in the field of manufacturing industry.
