Abstract [en]

The competitive situation within the process industry has increased due to the global industrialization. Companies operative within the industry are being forced to develop more efficient supply chains in order to sustain their competitive advantage on the market. An efficient supply chain is characterized by a combination of material and information flow where the objective is to reduce costs via reduced throughput times and material that arrives when needed. The purpose of this study is to obtain an understanding concerning factors that characterize an efficient supply chain within the mining industry with focus on reducing costs associated with material handling. Furthermore, this study aims to design a cost-effective supply chain within the mining industry. A case study is conducted at Boliden Mineral AB, where focus has been on the total supply chain from the mines to the concentrator within the Boliden area. Boliden Mineral AB is operative within the mining industry, belonging to the process industry, with their core competence ore mining where the minerals mainly consist of copper, zinc, lead, gold, and silver. The data has been gathered through interviews, observations, and written materials in both literature and from Boliden Mineral ABs intranet. This method has created conditions for the authors of this study to obtain an understanding about affecting factors on an efficient supply chain within the mining industry. The collected data has been summarized in a description of the current situation which has been the main source of information to identify the factors that negatively affect the material flow between mines and concentrator within the studied company. The most important thing for the company to take into account is to reduce the variations in the system in order to increase the availability. In order to reduce the variations this study has resulted in a template for reporting any unforeseen blockages that affects the material flow. Based on a summary of the reported data, target areas for improvement can be identified. Furthermore, a recommendation has been given about changing the shift form of ore transports. This would result in more leveled out material flows that leads to lowered storage levels due to that material is arriving when needed. The recommended shift form concludes that the total amount of trucks needed can be reduced which leads to a safer traffic situation. This recommendation would generate a cost reduction for Boliden Mineral AB because of a reduced amount of material handling and less bound capital in storage. Additionally, an efficient supply chain needs a material flow that is supported by an information flow. Thereby, the authors of this study have developed activities along with responsibilities that are needed in order to achieve efficiency in the information flow. These recommendations would generate an increased control and a capacity to manage the material flow within the company. This will result in shorter throughput times since material is arriving when needed and reduced storage levels, which will lead to a cost reduction.
