Optimalizace procesu plánování produkce na VAS centru u logistického poskytovatele

This Master´s thesis deals with optimization of the production planning process at the completion centre (= Value Added Service centre) of a logistics provider HOPI. The aim of this thesis was to verify the applicability of DMAIC methods of Lean Six Sigma philosophy to the production planning process in the company HOPI. The next aim was to improve the production planning process on the basis of DMAIC methods with regard to the efficiency of the process. Five phases of the DMAIC cycle were applied in order to achieve the goals. First, using the SIPOC and Voice of the Customer tools, the process was defined. In order to use the tools, data from personal interviews with HOPI employees were drawn. Afterwards the Value Stream Map of the entire process was built based on the process time measurements of the single process activities. 1980 pallets were measured. Measured data were analysed and a main problem of the monitored process, which is delay in the production, was identified. Using the Ishikawa diagram, possible causes of the delay were identified. Based on data analysis, process improvements which led to an increase in the efficiency of the production planning process, have been proposed. Finally, basic control steps were presented. The findings can be used by HOPI to improve the production planning process, increase the process efficiency and improve the company's profitability.
