Kartläggning och förbättring av internt logistikflöde

Sammanfattning: Globalisation has led to increased competition among companies, operating both locally and internationally. As a result, it has become crucial to stand out on the market by working cost-effectively, meeting customer requirements, offering short delivery times, smart material planning, among other things. New conditions, ranging from technological advancements to environmental demands, have prompted companies to focus on improving their material flow. The concept of logistics, along with lean-production, is now being recognized as a powerful tool. The purpose of this thesis is to gain a deeper understanding of wastes in a company's internal logistics flow and provide improvement suggestions for enhancing efficiency. The goal is to provide a foundation for future enhancements in the logistics flow of a manufacturing operation. To achieve the study's objectives and address the research questions, a case study is performed. The study will consist of a three-step plan. In the first stage, the problem is discussed, a literature study is carried out and suitable methods are identified. The next stage involves gathering information through interviews, observations, and documentation. Data is analysed and evaluated according to lean-principles. In the last phase, improvement proposals are developed based on the analysis. Theoretical approaches include deduction. The study employs both qualitative and quantitative research methods. The improvement suggestions are presented in the results chapter, categorized into general proposals, material handling, mapping, as well as a spaghetti diagram of the future state. The proposals focus on creating a continuous flow in production and minimizing security flaws. In addition, it is justified why a pulling-system and kanban-system should be introduced. The value stream mapping of the future state shows theoretically that the lead time can be halved if the stock size is minimized. The study analysed internal logistics waste and provided a basis for future projects. Using value stream mapping and spaghetti diagram, the authors successfully identified various improvement suggestions. For future research, it is recommended to include areas such as education, economic calculations, PDCA implementation, order and hook analysis, waste reduction, and optimal utilization of production space in the development process.
