  1. 1. Improving Visibility Forecasts in Denmark Using Machine Learning Post-processing

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : August Thomasson; [2023]
    Keywords : visibility forecast; fog; machine learning; numerical weather predicition; XGBoost; Random Forest; siktprognos; dimma; maskininlärning; numerisk vädermodell; XGBoost; Random Forest;

    Abstract : Accurate fog prediction is an important task facing forecast centers since low visibility can affect anthropogenic systems, such as aviation. Therefore, this study investigates the use of Machine Learning classification algorithms for post-processing the output of the Danish Meteorological Institute’s operational Numerical Weather Prediction (NWP) model to improve visibility prediction.

  3. 2. Forecasting Inventory Quantities : Time Series Models for Visualizing Fluctuations within Outbound Logistics

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Johan Lagerström; Lisa Sundström; [2022]
    Keywords : Outbound Logistics; Forecasting; Fluctuations; Time Series Analysis; Inventory space; 3PL;

    Abstract : Forecasting demand is one of the processes which greatly influences the decision making within a company, and it is also one of the greatest sources of uncertainty. Inaccurate forecasts force companies to find ways to compensate for the uncertainty, often by building inventories. READ MORE

  4. 3. Root Cause Analysis for In-Transit Time Performance : Time Series Analysis for Inbound Quantity Received into Warehouse

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Raman Ali; [2021]
    Keywords : Logistic; Time Series; Forecast; Inbound logistics; In-Transit;

    Abstract : Cytiva is a global provider of technologies to global pharmaceutical companies and it is critical to ensure that Cytiva’s customers receive deliveries of products on-time. Cytiva’s products are shipped via road transportation within most parts of Europe and for the rest in the world air freight is used. READ MORE

  5. 4. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elin Kindlundh; [2020]
    Keywords : HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

    Abstract : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.

  6. 5. Change of organizational structure and replenishment processes for increased customer service and profitability

    University essay from Linköpings universitet/Logistik- och kvalitetsutveckling

    Author : Linnea Akre; Eva Wiksten; [2016]
    Keywords : ;

    Abstract : This case study is based on Company XY's Paper division and aims to present a new organizational structure and best practices for the processes involved in replenishing. Furthermore, proposals for future actions to be executed by Company XY to increase the customer service and profitability will be proposed. READ MORE
