Effektiv lagerstyrning och samordnade transporter ifrån Asien: En fallstudie hos AJ Produkter AB
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Globalization constantly alters the dynamics of competition between countries, companies and industries. Improved communication and increased availability have, through reduced trade barriers, exposed markets on an international level. The competition has thereby drastically increased, where an increased quality constantly is demanded for a decreased price. At the same time, the globalization constantly increases the complexity of supply chains. Consequently, this causes inefficiency, which can be addressed by the consolidation of processes and activities. This study has been conducted in cooperation with AJ Produkter, whom sells furnishing, equipment and accessories for organizations, schools and sports facilities. The headquarter as well as central warehouse of AJ Produkter is located in Halmstad, Sweden. About 5000 articles are stocked here, with about 10 % being procured from Asia. Problems, regarding the purchasing from Asia, has been identified due to the fact that the inventory control is handled partially manually. These problems include overlay, recurring shortage and an uneven flow of supply. The purpose of this study is to investigate whether cost savings are possible for the flow of goods from Asia, through the use of consolidated transports. In order to address the core ussie, the underlying structure of the operational purchasing from Asia has to be investigated too. Thereby, the purpose also includes the optimization of the inventory control for the relevant articles. In this study, cost savings are synonymous with improvements. However, cost savings may have a direct negative impact for the customer. To avoid the occurrence of this negative correlation, cost savings is set in relation to service level. The study has been designed as a comparison in order to reach the stated purpose. The comparison is made between the current state and the result from an optimization model, where the model is built upon several inventory control policies as well as the theory of total cost of ownership. The main aspects that are compared are the total cost and the service level. Further, there’s also comparisons addressing the identified problems. The study establishes that it is possible to obtain cost savings as well as increased service levels, through the use of optimization of inventory control parameters and consolidated transports. According to the theory of total cost of ownership, a monetary savings potential of 8.34 % has been identified, at the same time as the service level increased with 21.64 percentage points. Further, the total transported volume dropped by 8.70 %, together with a decreased spread of incoming deliveries by 44.13 %. Above this, it’s possible to draw conclusions regarding further abstract, as well as monetary, cost savings that might have a positive effect. To be able to take advantage of the potential opportunities of improvement, AJ Produkter is recommended to implement software that is capable of automatically handling the developed optimization algorithm. The algorithm also causes the renegotiating of current framework agreements, due to changes in the shipping conditions. Further on, AJ Produkter is recommended to investigate the possibility of applying the optimization model on additional articles.
