Tiivistelmä
This thesis was implemented to raw material logistics to from Port of Rauma to the Smelter of Boliden Harjavalta and introducing different phases of the logistic chain. Qualitative research was implemented, and various data sources were applied on defining and measurement phase. The final analysis was interpretative due to the uneven flow of arrived containers that caused overtime.
The research target of the thesis was to evaluate the capacity of the different phases of the logistic chain and investigate what actions are needed to increase the total capacity of throughput when applying normal 40 hours of working per week. The evaluation process was done according to the guidelines and theory base of the Lean philosophy.
The main method of the study was DMAIC and bottle-neck analysis, and both were implemented in action.
During the study, the logistic process was defined and chopped to smaller subprocesses, these phases were measured based on the available existing data and the remaining gaps were filled with the help of professional parties involved. Then the achieved data was analyzed with the bottleneck analysis to find the subprocesses to be focused on. Finally, improvements were applied to certain phases, and controlling was done by following the increased capacity on a weekly basis.
The purpose of the thesis is to optimize container logistics of raw materials. After the proposed improvements, Boliden Harjavalta would be able to increase the volume of raw materials in containers and decrease the operating expenses (OPEX) per received tonnage. According to the study, existing logistic process achieved notifiable improvements in capacity and can be considered to sensitively optimized that before implementation the LEAN philosophy.
